CAIRO_HAS_XLIB_BACKEND to CAIRO_HAS_XLIB_SURFACE. | |
2003-12-03 Carl Worth <cworth@east.isi.edu> | |
* configure.in: Bumped version to 0.1.14 to indicate dropped | |
cairo-xlib.h and new cairo-config.h. | |
* New support for "./configure --without-x" to compile without the | |
xlib backend. Many thanks to Sasha V. <sasha@aftercode.net>. | |
* configure.in: We do three things here: Make the pkg-config check | |
for xrender conditional, set XLIB_BACKEND_DEFINE to either | |
CAIRO_HAS_XLIB_BACKEND or CAIRO_HAS_NO_XLIB_BACKEND to be | |
substituted into cairo-config.h, and set an AM_CONDITIONAL for | |
HAVE_XLIB_BACKEND to enable conditional compilation of | |
cairo_xlib_surface.c. Perhaps that could be simplified a tad, but | |
it's what we have working now. Also split up various | |
PKG_CHECK_MODULES into separate checks. | |
* src/cairo_gstate.c: Remove errant reference to | |
cairo_gstate_set_drawable. | |
* src/cairo.h: Move xlib-specific calls in from old cairo-xlib.h, | |
now guarded in #ifdef CAIRO_HAS_XLIB_BACKEND. | |
* src/Makefile.am (libcairo_xlib_sources): Make compilation of | |
cairo_xlib_surface.c conditional. | |
(INCLUDES, libcairo_la_LIBADD): Add the new variables from | |
splitting up the PKG_CHECK_MODULES calls. | |
2003-12-03 Carl Worth <cworth@east.isi.edu> | |
* cairo.pc.in (Libs): Add -lz for the compress function used in | |
the PS backend. | |
2003-12-01 Keith Packard <keithp@keithp.com> | |
* TODO: | |
Add note about degenerate path caps being broken | |
2003-11-21 Carl Worth <cworth@east.isi.edu> | |
* src/cairo_polygon.c (_cairo_polygon_add_edge): Use 0 and 1 not | |
False and True, (to avoid false dependency on X headers). | |
* src/cairo_path_stroke.c (_compute_face): Use | |
cairo_point_double_t not XPointDouble, (to avoid false dependency | |
on X headers). Thanks to "Sasha V." <sasha@aftercode.net> for | |
pointing these out. | |
2003-11-18 Carl Worth <cworth@east.isi.edu> | |
* configure.in: Bump version to 0.1.13 for new freetype header | |
compatibility. | |
Fix comments regarding freetype version checking. | |
2003-11-18 James Henstridge <james@daa.com.au> | |
* cairo.pc.in (Cflags): add FREETYPE_CFLAGS/LIBS to Libs/Cflags | |
rather than requiring "freetype2", which doesn't exist in anything | |
but the most recent version of freetype. | |
* configure.in (FREETYPE_LIBS): add freetype cflags/libs | |
substitutions. | |
2003-11-18 Carl Worth <cworth@east.isi.edu> | |
* src/cairo.h: Fix build for new freetype header include | |
mechanism, (thanks to Christof Petig <christof@petig-baender.de>) | |
2003-11-17 Carl Worth <cworth@isi.edu> | |
* Remove infinite looping when stroking with a line width at or | |
close to 0.0. Thanks to Rob Buis <buis@kde.org> and Noah Levitt | |
<nlevitt@columbia.edu> for providing in-the-wild examples of SVG | |
files with stroke-width:0 that demonstrated the problem, | |
(cowboy.svg and albania.svg). | |
* src/cairo_pen.c (_cairo_pen_stroke_spline): Do nothing if the | |
pen is a degenerate, single point. This happens when the line | |
width is a very small, non-zero value. | |
* src/cairo_gstate.c (_cairo_gstate_stroke): Do nothing when asked | |
to stroke a path with a line_width of 0.0. Previously, this would | |
lead to an infinite loop. | |
* src/cairo.c (cairo_set_line_width): Force negative line width | |
to 0.0. | |
* TODO: Updated TODO list. | |
2003-11-10 Carl Worth <cworth@east.isi.edu> | |
* configure.in: Fix typo (thanks to John Ellson | |
<ellson@research.att.com>) | |

* src/cairo.c (cairo_in_stroke): | |
(cairo_in_fill): Added new cairo_in_stroke and cairo_in_fill. | |
* src/cairo_traps.c (_cairo_trap_contains): | |
(_cairo_traps_contain): * src/cairo_gstate.c | |
(_cairo_gstate_in_stroke): | |
(_cairo_gstate_in_fill): New functions to support for | |
cairo_in_stroke and cairo_in_fill. Many thanks to Thomas Hunger | |
<info@teh-web.de> for the initial implementation which | |
demonstrated how easy this would be and pushed me to go and write | |
it already. | |
* src/cairo_gstate.c (_cairo_gstate_clip_and_composite_trapezoids): | |
* src/cairo_traps.c (_line_segs_intersect_ceil): | |
* src/cairo_path.c (_cairo_path_move_to): | |
(_cairo_path_line_to): | |
(_cairo_path_curve_to): Fixed to use _cairo_fixed_from_double | |
instead of XDoubleToFixed. | |
2003-11-06 Carl Worth <cworth@east.isi.edu> | |
* src/cairo.c (cairo_current_font): Move declaration to beginning | |
of function to avoid requiring a C99-compatible compiler. | |
* src/cairo.h: Add comment pondering memory management semantics | |
of cairo_current_target_surface. | |
* src/cairo_pen.c (_cairo_pen_fini): NULL out pen->vertices after | |
free. | |
* src/cairo_image_surface.c | |
(_cairo_image_abstract_surface_destroy): NULL out durface->data | |
after free. | |
2003-11-04 Carl Worth <cworth@east.isi.edu> | |
* src/cairo_gstate.c (_cairo_gstate_set_target_surface): Enable | |
cairo_set_target_surface (cr, NULL) to work. This can be useful to | |
force the current target surface to be finalized. | |
* configure.in: | |
* cairo.pc.in (Requires): Add explicit fontconfig and freetype2 | |
dependencies that were implicitly dropped along with Xft. | |
2003-11-04 Carl Worth <cworth@isi.edu> | |
* TODO: Note that cairo_show_page, cairo_copy_page, PostScript | |
backend, "real" text API, and text support for the image backend | |
have now all been implemented. | |
2003-11-04 Carl Worth <cworth@east.isi.edu> | |
* configure.in: | |
* cairo.pc.in (Requires): cairo doesn't depend on Xft after the | |
recent text work. | |
2003-11-03 Carl Worth <cworth@isi.edu> | |
* configure.in (CAIRO_VERSION): Bump version to 0.1.11 for new | |
cairo_copy_page. | |
* src/cairo_ps_surface.c (cairo_ps_surface_create): Now print | |
header at time of surface_create rather than in show_page. | |
(_cairo_ps_surface_destroy): Print document footer at time of | |
surface_destroy rather than in show_page. | |
(_cairo_ps_surface_erase): New function for sharing. | |
(_cairo_ps_surface_copy_page): Now keep proper page count. | |
(_cairo_ps_surface_show_page): Real work is now done in | |
copy_page. show_page is only distinct in that it erases the | |
surface afterwards. | |
* src/cairo.h: | |
* src/cairo.c (cairo_copy_page): | |
* src/cairo_gstate.c (_cairo_gstate_copy_page): | |
* src/cairo_surface.c (_cairo_surface_copy_page): | |
* src/cairo_image_surface.c (_cairo_image_surface_copy_page): | |
* src/cairo_xlib_surface.c (_cairo_xlib_surface_copy_page): Add | |
support for new cairo_copy_page function. | |
2003-11-03 Carl Worth <cworth@isi.edu> | |
* src/cairo_ps_surface.c (cairo_set_target_ps): Add missing check | |
for out of memory. | |
* src/cairo_image_surface.c | |
(_cairo_image_surface_create_with_masks): | |
(_cairo_image_surface_create_with_masks): | |
(cairo_image_surface_create): | |
(cairo_image_surface_create): | |
(cairo_image_surface_create_for_data): | |
(cairo_image_surface_create_for_data): Add several missing checks | |
for out of memory. | |
2003-11-03 Carl Worth <cworth@east.isi.edu> | |
* src/cairo.h: Added __external_linkage to a few functions that | |
were missing it. | |
2003-11-01 Carl Worth <cworth@isi.edu> | |
* src/cairo_ps_surface.c (_cairo_ps_surface_show_page): Fix | |
misplacement of PS origin, (was translating vertically by width | |
instead of height). | |
* configure.in (CAIRO_VERSION): Bumped version to 0.1.10 for new | |
functions cairo_set_target_ps, cairo_ps_surface_create, and | |
cairo_show_page. | |
* src/cairo_ps_surface.c: New file with preliminary support for | |
drawing to a PostScript file. Most of the ps_surface backend | |
functions are just tiny wrappers, deferring to image_surface | |
functions to do the real work. Then, in show_page, the image is | |
compressed and spit out into the file. Crude and effective. | |
* src/cairo.c (cairo_show_page): | |
* src/cairo_gstate.c (_cairo_gstate_show_page): | |
* src/cairo_image_surface (_cairo_image_surface_show_page): | |
* src/cairo_xlib_surface.c (_cairo_xlib_surface_show_page): | |
* src/cairo_surface.c (_cairo_surface_show_page): Implement new | |
support for cairo_show_page -- just a stub in the non-PS surfaces. | |
* src/cairo_image_surface.c (_cairo_image_surface_set_filter): | |
Export this function for internal use. | |
* src/cairo.h: Added cairo_set_target_ps, cairo_ps_surface_create, | |
and cairo_show_page. Noted plans for new cairo_surface_clip_begin, | |
perhaps moving some cairo_surface functions to cairo_set_pattern, | |
and possibly renaming cairo_matrix_t to cairo_transform_t. | |
* src/Makefile.am (libcairo_la_SOURCES): Added cairo_ps_surface.c. | |
2003-10-31 Carl Worth <cworth@isi.edu> | |
* src/cairo_gstate.c (_cairo_gstate_arc): | |
(_cairo_gstate_arc_negative): Do nothing when radius <= 0.0, | |
(which is much better than the current infinite loop). | |
2003-10-31 Carl Worth <cworth@isi.edu> | |
* Moved all libic-related drawing into cairo_image_surface.c. | |
Details below: | |
* src/cairo_xlib_surface.c: Add width, height, format to | |
cairo_xlib_surface_t. | |
(_cairo_xlib_surface_get_image): | |
(_cairo_xlib_surface_set_image): Implement new get_image/set_image | |
interface instead of pull_image/push_image. | |
(_cairo_xlib_surface_get_image): Fix memory leak that showed up | |
with non-Render servers. | |
(_cairo_xlib_surface_set_matrix): Implement set_matrix with new | |
interface. | |
(_render_operator): Translate from cairo_operator_t to | |
Render-defined operator values rather than assuming they are the | |
same. | |
* src/cairo_surface.c: Move all libic-related code into | |
cairo_image_surface.c. cairo_surface is now a thin wrapper around | |
concrete surface types, (with fallback code to cairo_image_surface | |
whenever a backend does not provide support for a particular | |
function). Remove checks for NULL backend functions. | |
(_cairo_surface_get_image): | |
(_cairo_surface_set_image): New interface to replace | |
pull_image/push_image. Now uses a cairo_image_surface rather than | |
an IcImage and now also passes it externally rather than storing | |
it in the surface. | |
* src/cairo_gstate.c (_cairo_gstate_fini): | |
(_cairo_gstate_set_target_surface): | |
(_cairo_gstate_set_rgb_color): Avoid useless calls to | |
cairo_surface_destroy for NULL surfaces. | |
(_cairo_gstate_show_surface): | |
(_cairo_gstate_clip): | |
(_cairo_gstate_clip_and_composite_trapezoids): | |
(_cairo_gstate_begin_group): Add status checking for calls to | |
surface_create_similar, surface_fill_rectangles, | |
surface_composite, and surface_composite_trapezoids. | |
* src/cairo_ft_font.c (_cairo_ft_font_show_glyphs): Remove one | |
gratuitous level of nesting. | |
(_cairo_ft_font_show_glyphs): Bubble up NULL_MEMORY status. | |
* src/cairo.h: Portability improvements: Remove include of | |
X11/extensions/Xrender.h. Move include down near the freetype | |
include. | |
cairo_format_t: Eliminate Render-based values for this enum. | |
cairo_operator_t: Eliminate Render-based values. Drop | |
disjoint/conjoint operators. | |
cairo_filter_t: Eliminate libic-based values for this enum. | |
Add cairo_image_surface_create and cairo_image_surface_create_for_data. | |
* src/cairo.c (cairo_status_string): Add new CAIRO_STATUS_NULL_POINTER. | |
This can be returned only if the user passes a NULL object in to a | |
cairo function. | |
* src/cairoint.h: Move include of <X11/extensions/Xrender.h> from | |
cairo.h to here. | |
* src/Makefile.am (libcairo_la_SOURCES): Add | |
cairo_image_surface.c. Reformat line continuation characters. | |
* src/cairoint.h: Remove prototypes for obsolete functions: | |
_cairo_gstate_set_visual and _cairo_gstate_set_format. | |
2003-10-30 Carl Worth <cworth@isi.edu> | |
* src/cairo_xlib_surface.c (_cairo_xlib_surface_destroy): Fix | |
memory leaks of surface->gc and surface->ximage. | |
(_cairo_xlib_surface_composite): | |
(_cairo_xlib_surface_composite_trapezoids): Fix memory leaks of | |
cloned surfaces. | |
2003-10-30 Carl Worth <cworth@isi.edu> | |
* configure.in (CAIRO_VERSION): Bumped version to 0.1.9 for change | |
in argument list of cairo_ft_font_create. | |
* src/cairo_ft_font.c: A set of changes to eliminate the static | |
FT_Library field, (which could introduce nasty problems with | |
respect to threading). With the new code, each font created with | |
the toy API will own its own FT_Library. Meanwhile, | |
cairo_ft_font_create now accepts an FT_Library parameter. | |
* src/cairo_ft_font.c: Add ft_library field so that fonts that own | |
their own FT_Library can also clean it up. Eliminate static | |
FT_Library and _init_cairo_ft_lib. | |
(cairo_ft_font_create): Now accepts an FT_Library argument. | |
(_cairo_ft_font_create): Create an FT_Library owned by this font, | |
(this only happens as part of the "toy API") | |
(_cairo_ft_font_destroy): Clean up ft_font->ft_library if | |
necessary. | |
(cairo_ft_font_create_for_ft_face): Initialize ft_library and | |
owns_ft_library. | |
* src/cairo.h: Add FT_Library parameter to cairo_ft_font_create. | |
2003-10-30 Carl Worth <cworth@isi.edu> | |
* cairo_font: A few cleanups to eliminate a memory leak. | |
* src/cairo_gstate.c (_cairo_gstate_init_copy): | |
(_cairo_gstate_fini): | |
(_cairo_gstate_select_font): | |
(_cairo_gstate_set_font): Replace calls to _cairo_font_fini with | |
cairo_font_destroy. | |
* src/cairo_ft_font.c (_cairo_ft_font_destroy): Rename | |
_cairo_ft_font_close to _cairo_ft_font_destroy. | |
* src/cairo_font.c: Eliminate unnecessary cairo_font_fini | |
function. | |
(cairo_font_destroy): Put reference decerement here where it | |
belongs. | |
* src/cairoint.h: Eliminate unnecessart family, slant, and weight | |
fields from cairo_font_t. | |
Rname font backend->close to backend->destroy. | |
2003-10-28 Carl Worth <cworth@isi.edu> | |
* README: Updated to match latest text from web page. Fixed stale | |
references to Xc and xrtest. | |
2003-10-28 Carl Worth <cworth@isi.edu> | |
* src/cairo_xlib_surface.c (_cairo_xlib_surface_pixels_per_inch): | |
Implement new backend function. | |
* src/cairo_surface.c (_cairo_surface_pixels_per_inch): Add new | |
function to query surface pixels_per_inch. | |
* src/cairo_gstate.c (_cairo_gstate_init): Rename gstate->ppm to | |
gstate->pixels_per_inch. Swithc from default 3780 pixels per meter | |
to 96.0 pixels per inch which is slightly different. | |
2003-10-28 Carl Worth <cworth@isi.edu> | |
* src/cairo_gstate.c (_cairo_gstate_ensure_source): | |
(_cairo_gstate_clip_and_composite_trapezoids): | |
(_cairo_gstate_clip): | |
(_cairo_gstate_show_surface): Track changes to | |
_cairo_surface_create_similar_solid. | |
* src/cairo_surface.c (_cairo_surface_create_similar_solid): Now | |
that this function is internal, it can accept a cairo_color_t | |
which makes the interface much cleaner. | |
* src/cairo.h: Remove problematic function | |
cairo_surface_create_similar_solid from the public API. | |
2003-10-28 Carl Worth <cworth@isi.edu> | |
* src/cairo_surface.c (_cairo_surface_composite): | |
(_cairo_surface_fill_rectangles): | |
(_cairo_surface_composite_trapezoids): Fix bug introduced in last | |
commit: must check for NULL backend function before calling | |
through it. | |
2003-10-27 Carl Worth <cworth@isi.edu> | |
* src/cairo_surface.c (_cairo_surface_composite): | |
(_cairo_surface_fill_rectangles): | |

be NULL. Track new cairo_int_status_t return value for backend | |
drawing functions. | |
* src/cairo_xlib_surface.c: Remove casts when initializing | |
cairo_xlib_surface_backend. Rename cairo_xlib_surface as | |
cairo_xlib_surface_t. | |
(_cairo_xlib_surface_create_similar): | |

cairo_surface_backend API. | |
* src/cairoint.h: cairo_surface_backend now accepts a void * for | |
the virtual surface. | |
2003-10-27 Carl Worth <cworth@isi.edu> | |
* src/cairo_ft_font.c (_cairo_ft_font_create): Default to normal | |
slant/weight on out-of-range values. | |
Add missing include of fontconfig/fcfreetype.h. | |
2003-10-24 Keith Packard <keithp@keithp.com> | |
* src/cairo_ft_font.c: (_cairo_ft_font_show_glyphs): | |
A HORRIBLE KLUDGE to repad glyph images from freetype to | |
meet libic requirements. | |
2003-10-24 Carl Worth <cworth@east.isi.edu> | |
* src/cairo_ft_font.c (_init_cairo_ft_lib): Fix missing void from | |
function prototype. | |

* src/cairo.c (cairo_current_font): Fix missing return value. | |
* src/cairoint.h: No need for CAIRO_INT_STATUS_NULL_POINTER | |
(CAIRO_FONT_BACKEND_DEFAULT): Move declaration of default font | |
backend up into cairoint.h | |
* src/cairo_gstate.c (_cairo_gstate_init): Create a default font, | |
don't leave it NULL. | |
(_cairo_gstate_current_font): gstate->font must never be NULL. | |
(_cairo_gstate_current_font_extents): Can never be called with a | |
NULL gstate. | |
* src/cairo_font.c (_cairo_font_create): Rename | |
_cairo_font_create_font and move to top of file. | |
(_cairo_font_init, _cairo_font_scale, _cairo_font_transform) | |
(_cairo_font_text_extents, _cairo_font_glyph_extents) | |

* Many files: Fixed Copyright statements to read "University of | |
Southern California" rather than "USC, Information Sciences | |
Institute" as the university is the actual corporation. | |
2003-10-11 Carl Worth <cworth@isi.edu> | |
* src/cairo-xlib.h: Add extern "C" stuff. (Thanks to Soory Kuloor | |
for the reminder). | |
2003-10-09 Carl Worth <cworth@isi.edu> | |
* src/cairo_font.c: Stub out NULL_POINTER errors as | |
CAIRO_STATUS_SUCCESS so that drawing to off-screen images still | |
works even though text does not yet. | |
2003-10-04 Carl Worth <cworth@isi.edu> | |
* src/cairo_hull.c (_cairo_hull_compute): Add cairo_hull.c to | |
compute a convex hull, (using Graham scan algorithm). | |
* src/cairo_pen.c (_cairo_pen_add_points): Generate convex hull of | |
pen after adding new points. | |
* src/cairoint.h: Rename pen->vertex to pen->vertices | |
* Replaced "pt" with "point" in about a zillion places. | |
* src/cairo.c (cairo_destroy): Fix to continue with destroy even | |
in the face of non-zero status. | |

exposed cairo_path_t and related functions. | |
* src/cairo_path.c (cairo_path_create): | |

state out of cairo_gstate and into cairo_path. | |
(_cairo_gstate_copy): Renamed _cairo_gstate_clone to | |
_cairo_gstate_copy for consitency with other functions, (though I | |
may reconsider and rename all of them to _clone). | |
(_cairo_gstate_current_path): | |
(_cairo_gstate_set_path): New functions for "user path" support. | |
* src/cairo.h: Expose new opaque cairo_path_t object along with | |

2003-09-15 Carl Worth <cworth@east.isi.edu> | |
* configure.in: Require xrender >= 0.6.0 | |
* src/cairo_surface.c (_cairo_x11_surface_put_image): Make static. | |
2003-09-15 Carl Worth <cworth@isi.edu> | |
* src/cairo.c (cairo_restore): Fix to catch invalid restore rather | |
than just catching the second invalid restore. Fix from Keith | |
Packard <keithp@keithp.com>. | |
2003-09-12 Carl Worth <cworth@east.isi.edu> | |
* src/cairo_surface.c (cairo_surface_create_similar_solid): Don't | |

cairo_x11_surface_put_image. | |
(_cairo_surface_pull_image): | |
(_cairo_surface_push_image): First real implementation of | |
push/pull_image, (thanks for help from Graydon Hoare | |
<graydon@redhat.com>). This provides support for running Cairo on | |
X servers that do not have the RENDER extension. (Note: This is | |
still woefully slow). | |
* src/cairo_path_stroke.c (_cairo_stroker_join): Switch to | |
_cairo_fixed functions. | |
* src/cairo_path_bounds.c (_cairo_path_bounds): Use cairo_fixed | |
rather than X macros. | |

explicitly set, current point is (0,0) in user space. | |
(_cairo_gstate_show_text): Fix to place text at user-space origin | |
if there is no current point. | |
(_cairo_gstate_show_surface): Optimize to pass NULL mask if alpha | |

2003-09-05 Keith Packard <keithp@keithp.com> | |
* src/cairo_path_stroke.c: comment face computations, check for | |
reflecting transformation to select correct face orientations | |
* src/cairo_pen.c: check for reflecting transform when computing | |
pen to ensure consistent pen orientation | |
2003-09-05 Carl Worth <cworth@east.isi.edu> | |
* configure.in: Bumped version to 0.1.2 for new cairo_copy | |
function. | |
* src/cairo_gstate.c (_cairo_gstate_init): Fixed uninitialized | |
current_pt values. | |
(_cairo_gstate_clone): Force gstate->next to NULL after cloning, | |
to prevent the clone from trashing the former stack. | |
* src/cairo.c (cairo_create): Folded _cairo_init into cairo_create. | |
(cairo_destroy): Folded _cairo_fini into cairo_dstroy. | |
(cairo_copy): Added new cairo_copy function. | |
2003-09-05 Carl Worth <cworth@isi.edu> | |
* src/cairo_gstate.c (_cairo_gstate_show_text): Fix crash due to | |
missing call to ensure_source. | |
2003-09-04 Carl Worth <cworth@east.isi.edu> | |
* src/cairoint.h (DEPRECATE): Changed DEPRECATE mechanism to | |
preseve binary compatibility, but break source-level | |
compatibility. | |
2003-09-04 Carl Worth <cworth@isi.edu> | |
* src/cairo_gstate.c (_cairo_gstate_init): Combine gstate->pattern | |
and gstate->solid into a single gstate->source. | |
(_cairo_gstate_set_rgb_color): Defer creation of gstate->source | |
until the stroke or fill. | |
(_cairo_gstate_ensure_source): New function to combine duplicated | |
code. | |
(_cairo_gstate_stroke): | |
(_cairo_gstate_fill): Now must ensure that gstate->source has been | |
created. | |
* src/cairo.c (cairo_set_target_surface): | |
(cairo_set_target_drawable): | |
(cairo_set_target_image): These functions can now clear | |
status==CAIRO_STATUS_NO_TARGET_SURFACE. This is a clean solution | |
to the bug of a SEGV if cairo_stroke/cairo_fill are called before | |
cairo_set_target. | |
* BUGS: Removed two fixed bugs, (SEGV if cairo_set_rgb_color | |
called before cairo_set_target and SEGV if cairo_fill called | |
before cairo_set_rgb_color) | |
2003-09-04 Keith Packard <keithp@keithp.com> | |
* src/cairo_path_stroke.c: added comments describing miter | |
join code and miter limit computation. Replace XFoo with cairo_foo | |
for double and fixed | |
* src/cairoint.h: add cairo_fixed_to_double and cairo_double_to_fixed | |
Carl says he's got similar code, so he'll have to fix things if I | |
get this committed quickly enough. | |
2003-09-04 Carl Worth <cworth@isi.edu> | |
* util/cairo-api-update: Added script to update source code using | |
Cairo to the latest API. | |
* configure.in (CAIRO_VERSION): Bumped version to 0.1.1 | |
* src/cairoint.h (DEPRECATE): Added magic DEPRECATE macro which | |
provides an asm-based alias for old function names. This works on | |
ELF systems with gcc version >= 2. | |
* src/cairo.h (cairo_get_status_string): Deprecated all | |
cairo_get_* names in favor of cairo_current_*. The deprecated | |
function names will trigger either a warning or a link error, but | |
in both cases with a useful message giving both the old and new | |
name of the function. Three of the function name changes are | |
different than the single word substituion: | |
cairo_get_current_color -> cairo_current_color | |
cairo_get_status -> cairo_status | |
cairo_get_status_string -> cairo_status_string | |
2003-09-03 Carl Worth <cworth@east.isi.edu> | |
* src/cairo.h: Change cairo_get_matrix interface to accept a | |
cairo_matrix_t* rather than 6 double*. | |
* src/cairo.c (cairo_get_matrix): Add implementation of cairo_get_matrix. | |
2003-08-29 Carl Worth <cworth@isi.edu> | |
* src/cairo_surface.c (_cairo_surface_composite): Optimized case | |
where src is in memory, dst is on server, and mask is NULL. Will | |
now do a single XPutImage rather than the painful | |
GetImage/PutImage dance of the general code. | |
2003-08-28 Carl Worth <cworth at east.isi.edu> | |
* src/cairo_traps.c (_line_segs_intersect_ceil): One more | |
increment, (that still won't fix the bug). Added comment point to | |
Hobby's paper, (that will fix it). | |
* src/cairo_font.c (_cairo_font_resolve_xft_font): Fixed to use | |
fabs instead of abs when correcting for negative area expansion. | |
2003-08-28 Keith Packard <keithp@keithp.com | |
* src/cairo_font.c: font pixel size is always non-negative | |
2003-08-26 Carl Worth <cworth@isi.edu> | |

pattern at current point instead of the origin. | |
(_cairo_gstate_stroke): Fixed to properly transform pattern. | |
(_cairo_gstate_fill): Fixed to properly transform pattern. | |
2003-07-31 Richard Henderson <rth@twiddle.net> | |
* src/cairo_color.c (CAIRO_COLOR_DEFAULT): Mark const. | |
* src/cairo_matrix.c (CAIRO_MATRIX_IDENTITY): Likewise. | |
* src/cairo_path.c (num_args): Likewise. | |
* src/cairo_path_bounds.c (_cairo_path_bounds): Likewise for cb. | |
2003-07-31 Richard Henderson <rth@twiddle.net> | |
* cairo.pc.in: Depend on slim. | |
* configure.in: Check for slim. | |
* src/cairo.h: Include slim_{export,import}.h as needed; mark all | |
symbols __external_linkage. | |
* src/cairoint.h: Include slim_internal.h; mark all symbols | |
__internal_linkage. Provide slim_hidden_proto symbols as needed. | |
* src/cairo.c, src/cairo_matrix.c, src/cairo_surface.c, | |
Provide slim_hidden_def symbols as needed. | |
* src/cairo_traps.c (cairo_traps_add_trap): Mark static. | |
(cairo_traps_add_trap_from_points): Likewise. | |
2003-07-30 Carl Worth <cworth@isi.edu> | |
* configure.in (LIBIC_REQUIRED): Fixed some typos in the libic | |
PKG_CHECK. | |
* src/cairoint.h: | |
* src/cairo.c: Fixed a disagreement over whether some internal | |
cairo_gstate_t functions had an '_' prefix or not. | |
* src/cairo_traps.c (_line_segs_intersect_ceil): Add one more | |
conditional intersect to push past some fill bugs. | |
* src/cairo_surface.c (cairo_surface_create_for_drawable): | |
(cairo_surface_create_for_image): | |
(cairo_surface_put_image): | |
(_cairo_surface_pull_image): | |
(_cairo_surface_push_image): | |
(cairo_surface_set_matrix): | |
(cairo_surface_get_matrix): | |
(cairo_surface_set_repeat): | |
(_cairo_surface_composite): | |
(_cairo_surface_fill_rectangle): | |
(_cairo_surface_fill_rectangles): | |
(_cairo_surface_composite_trapezoids): Absorb all functionality | |
previously in the Xc library. | |
* src/cairo_pen.c (_cairo_pen_init): Don't store floating point | |
theta in the pen. Instead, sort vertices by fixed point slope | |
comparisons. | |
(_cairo_pen_add_points): Fixed to remove duplicate pen vertices | |
appearing at beginning and end of vertex array. | |
(_pen_vertex_compare): New fixed-point "angle" comparison for pen | |
vertices. A bit trickier than before, but much more accurate. | |
* src/cairo_path_stroke.c (_cairo_stroker_face_clockwise): Share | |
clockwise calculation with other modules. | |
* src/cairo_path_bounds.c: | |
* src/cairo_path_fill.c: | |
* src/cairo_path_stroke.c: | |
* src/cairo_pen.c: | |
* src/cairo_polygon.c: | |
* src/cairo_spline.c: | |
* src/cairo_traps.c: | |
* src/cairo_path.c: Replaced all references to | |
XFixed, XPointFixed, XLineFixed, and XTrapezoid with new | |
cairo_fixed_t, cairo_point_t, cairo_line_t, and cairo_trapezoid_t. | |
* src/cairo_path.c: (_cairo_path_interpret): Made the path | |
interpreter callback names consistent, (eg. add_edge rather than | |
AddEdge). | |
* src/cairo_gstate.c (_cairo_gstate_text_extents): Now silently | |
exits for a non X surface, (avoids a crash until we can implement | |
the libic text backend). | |
* src/cairo_gstate.c (_cairo_gstate_end_group): | |
(_cairo_gstate_clip_and_composite_trapezoids): | |
(_cairo_gstate_show_surface): Replaced all XcCalls with | |
corresponding cairo_surface_calls. | |
* src/cairo_gstate.c (_cairo_gstate_transform_point): | |
(_cairo_gstate_transform_font): | |
(_cairo_gstate_text_extents): Renamed from the garbled names | |
(eg. cairo_gstateransform_point) leftover from the great renaming. | |
* src/cairo_color.c (_cairo_color_set_rgb): Reworked cairo_color_t | |
to eliminate reference to an XcColor object. | |
* src/cairo.h: Dropped include of <Xc.h>, added | |
<X11/extensions/Xrender.h>, <fontconfig/fontconfig.h>, and <ic.h> | |
* src/cairo.c (cairo_get_fill_rule): Added missing cairo_get_fill_rule. | |
* configure.in (PKG_CHECK_MODULES): Drops xc, add libic | |
* cairo.pc.in (Requires): Drop xc, add libic. | |
2003-07-25 Carl Worth <cworth@isi.edu> | |
* src/cairo_traps.c (_line_segs_intersect_ceil): We don't need a | |
loop here, (just a conditional increment). This time, we've | |
actually done the error analysis to back this up. | |
2003-07-24 Carl Worth <cworth@isi.edu> | |
* src/cairo_traps.c (cairo_traps_tessellate_polygon): Massive | |
cleanup of polygon tessellation, (it might actually be correct | |
now). | |
2003-07-23 Carl Worth <cworth@isi.edu> | |
* src/cairoint.h: Introduced some cairo_fixed_*_t types. This is | |
the first baby step toward ripping X dependencies out of the Cairo | |
headers. | |
* src/cairo_traps.c (_compute_x): Converted from floating point to | |
fixed point. | |
(_line_seg_intersection_ceil): Now increments y value once if the | |
initial y value computed is less than the actual intersection | |
point. | |
* src/cairo_traps.c (_compare_cairo_edge_by_slope): Converted from | |
floating point to fixed point. | |
* src/cairo_pen.c (_slope_clockwise): Converted from floating | |
point to fixed point. | |
2003-07-19 Carl Worth <cworth@isi.edu> | |
* src/cairo_traps.c (cairo_traps_tessellate_polygon): Fixed some | |
sorting problems with two intersections very near the same | |
vertical position. (There are still some reamining problems | |
though). | |
(cairo_traps_tessellate_polygon): Better fix for the same | |
bug. Should cover all cases, (and it's moe efficient too). | |
2003-07-18 Carl Worth <cworth@east.isi.edu> | |
* src/cairo.h: Fixed some inconsistent tag/typedef names that were | |
missed in the great renaming. | |
2003-07-18 Carl Worth <cworth@isi.edu> | |
* src/cairo.h: Renamed everything from Xr* to cairo_*. | |
* util/xr2cairo: Added utility script xr2cairo to help users fix | |
their source code. | |
2003-07-03 Carl Worth <cworth@isi.edu> | |
* src/xrmatrix.c (XrMatrixGetAffine): Added XrMatrixGetAffine | |
(from Soorya Kuloor) | |
* src/xr.c (XrGetAlpha): Added XrGetAlpha | |
(XrGetRGBColor): Added XrGetRGBColor | |
2003-06-12 Carl Worth <cworth@isi.edu> | |
* src/xrgstate.c (_XrGStateScale): Scale by 0 now causes an | |
InvalidMatrix error. | |
2003-05-28 Carl Worth <cworth@isi.edu> | |
* src/xrmatrix.c (XrMatrixMultiply): Eliminated | |
_XrMatrixMultiplyIntoRight and _XrMatrixMultiplyIntoLeft. | |
* src/xrgstate.c (_XrGStateClipAndCompositeTrapezoids): Fixed | |
missing translation of clip surface. | |
* src/Xr.h: Added XrSurfacePutImage | |
2003-05-16 Carl Worth <cworth@isi.edu> | |
* src/xrint.h: Added ppm filed (pixels per meter) to both | |
XrSurface and XrGState. | |
* src/xrgstate.c (_XrGStateSetTargetSurface): Fixup CTM according | |
to change in surface->ppm. | |
(_XrGStateDefaultMatrix): Default matrix is no longer an identity | |
matrix, but rather a matrix that provides some relates user space | |
units to real-world dimensions in a meaningful way, (default 3780 | |
user space units per meter). This conversion is not exact, but is | |
rather as close as possible while also guaranteeing that one user | |
space unit maps to an integer number of device pixels. | |
2003-05-15 Carl Worth <cworth@isi.edu> | |
* src/xr.c (XrSetTargetDrawable): Moved implementation up from | |
_XrGStateSetTargetDrawable, (eg. all convenience functions should | |
be taken care of at the xr.c level ratehr than xrgstate.c) | |
* src/Xr.h: Added convenience function XrSetTargetImage | |
2003-05-14 Carl Worth <cworth@isi.edu> | |
* src/xrfont.c (_XrFontResolveXftFont): Fixed fonts to pull | |
pixelsize out of the transformation matrix. Fonts are now properly | |
hinted regardless of scaling. | |
* src/Xr.h: Three new functions for manipulating surfaces: | |
XrSurfaceSetMatrix, XrSurfaceGetMatrix, XrSurfaceSetFilter. | |
* src/Xr.h: Removed broken XrShowImage* functions. Changed | |
XrShowSurface to not require X/Y but instead depend on the CTM for | |
translation, (or the surface transformation matrix). I'd like to | |
get rid of width/height as well but it turns out an XrSurface is | |
not aware of its dimensions. | |
* src/Xr.h: Added convenience function for building rectangular | |
paths: XrRectangle. | |
* src/Xr.h: Added functions for performing transformations with | |
the CTM and its inverse: XrTransformPoint, XrTransformDistance, | |
XrInverseTransformPoint, XrInverseTransformDistance. | |
* src/Xr.h: XrConcatMatrix and XrSetMatrix now accept a pointer to | |
an XrMatrix rather than 6 doubles. | |
* src/Xr.h: Now exporting opaque XrMatrix object with several | |
functions: XrMatrixCreate, XrMatrixDestroy, XrMatrixCopy, | |
XrMatrixSetIdentity, XrMatrixSetAffine, XrMatrixTranslate, | |
XrMatrixScale, XrMatrixRotate, XrMatrixInvert, XrMatrixMultiply, | |
XrMatrixTransformDistance, XrMatrixTransformPoint. | |
2003-05-12 Carl Worth <cworth@isi.edu> | |
* src/Xr.h: Added XrSetPattern. See also XrSurfaceSetRepeat. | |
* src/xrpathbounds.c (_XrPathBounds): Moved path bound computation | |
to its own file. | |
* src/xrpathstroke.c (_XrPathStrokeToTraps): Moved path stroking | |
to its own file. | |
* src/xrpathfill.c (_XrPathFillToTraps): Moved path fililng to its | |
own file. | |
* src/xrgstate.c (_XrGStateStroke): | |
(_XrGStateFill): | |
(_XrGStateClipAndCompositeTrapezoids): Reorganized stroke and fill | |
code to go through the same path for clipping. | |
2003-05-02 Carl Worth <cworth@east.isi.edu> | |
* src/Xr.h: Changed XrFormatRGB32 to XrFormatRGB24 | |
* src/xrsurface.c (_XrFormatBPP, XrSurfaceCreateForImage) | |
(_XrFormatDepth): Fixed for change of XrFormatRGB32 to | |
XrFormatRGB24 | |
2003-05-01 Carl Worth <cworth@isi.edu> | |
* src/xrpath.c (_XrPathBounderInit): | |
(_XrPathBounderDeinit): | |
(_XrPathBounderAddPoint): | |
(_XrPathBounderAddEdge): | |
(_XrPathBounderAddSpline): | |
(_XrPathBounderDoneSubPath): | |
(_XrPathBounderDonePath): | |
(_XrPathBounds): New support for computing the bounding box of a | |
path. Currently used internally, (for computing the size of the | |
clip surface), and not exported publically. | |
* src/xrgstate.c (_XrGStateStroke): Implemented clip support for | |
strokes. | |
(_XrGStateClip): New _XrGStateClip function fills the current path | |
onto the gstate->clip surface. | |
* src/xr.c (XrClip): Added preliminary/experimental clip | |
functionality. The current implementation only clips stroked | |
elements, (not fills, images, or text). It's alway quite | |
inefficeient. | |
* src/xr.c (XrGetOperator): | |
(XrGetTolerance): | |
(XrGetLineWidth): | |
(XrGetLineCap): | |
(XrGetLineJoin): | |
(XrGetMiterLimit): | |
(XrGetCurrentPoint): Added several new query functions. | |
2003-04-26 Carl Worth <cworth@isi.edu> | |
* src/xrsurface.c (XrSurfaceDestroy): Fix memory leak of | |
surface->image_data. | |
2003-04-25 Carl Worth <cworth@east.isi.edu> | |
* configure.in: Fixed libtool versioning | |
2003-04-17 Carl Worth <cworth@isi.edu> | |
* Switched from imake to autotools. | |
* src/xrint.h: XrSurface structure is now greatly simplified, | |
(details now handled by XcSurface). | |
* src/Xr.h: Eliminated Display * parameter so Xr can be used for | |
non-X drawing. | |
Removed XrPushGroup/XrPopGroup. | |
Replaced XrSetDrawable/XrSetVisual with XrSetTargetDrawable. | |
Added XrSetTargetSurface and several new XrSurfaceCreate | |
functions. | |
Added XrShowSurface, (functionality overlaps with XrShowImage -- | |
need to fix this) | |
2003-02-14 Carl Worth <cworth@east.isi.edu> | |
* xrgstate.c (_XrGStateShowImageTransform): Fixed transformed | |
images which were sometimes 1 pixel too tall/wide. | |
2003-02-06 Carl Worth <cworth@isi.edu> | |
* xrpen.c (_XrPenVerticesNeeded): Fixed to use determinant rather | |
than eigenvalues to compute maximal scaling of radius. Now avoids | |
embarrassing segfaults due to NaN from the eigenvalue computation. | |
2003-01-28 Carl Worth <cworth@isi.edu> | |
* xrtraps.c (_XrTrapsTessellateTriangle): Fixed to not re-order | |
the array provided as an argument. (Note: the rectangle and | |
polyghon tessellators still perform reordering). | |
* xrstroker.c (_XrStrokerJoin): | |
(_XrStrokerCap): Implemented round caps and joins. | |
(_XrStrokerDoneSubPath): Fixed initial cap, (was always being | |
drawn on the inside previously). | |
* xrpen.c (_XrPenInit): Fixed to keep pen vertex theta values all | |
in device space. | |
(_XrPenAddPoints): Removed the silly flags from the pen vertices, | |
(in favor of just using the FindActiveVertex functions) | |
(_XrPenFindActiveCWVertexIndex): | |
(_XrPenFindActiveCCWVertexIndex): Added functions needed for round | |
caps/joins. | |
* xrgstate.c (_XrGStateSetDash): Fixed to accept a NULL dash array | |
to revert to no dashing. | |
2003-01-28 Carl Worth <cworth@east.isi.edu> | |
* xrtraps.c (_XrTrapsTessellateTriangle): Restored triangle | |
tessellation functionality, (I think it's correct this time). | |
* xrstroker.c (_XrStrokerJoin): Bevel joins now use triangle | |
tessellation rather than polygon tessellation. | |
2003-01-24 Carl Worth <cworth@east.isi.edu> | |
* xrpolygon.c (_XrPolygonAddEdge): Fixed to handle multiple | |
sub-polygons. | |
* xrstroker.c (_XrStrokerJoin): Fixed handling of miter limit. | |
* local.def: Added local.def for building outside the xc tree. | |
2002-12-03 Carl Worth <cworth@isi.edu> | |
* xrstroker.c (_XrStrokerJoin): | |
(_XrStrokerCap): Fixed to track change in winding rule parameter | |
to XrTrapsTessellatePolygon, (otherwise self-intersecting splines | |
suddenly had holes). | |
* xrpen.c (_XrPenStrokeSpline): Fixed to track change in winding | |
rule parameter to XrTrapsTessellatePolygon. | |
2002-11-11 Carl Worth <cworth@isi.edu> | |
* xrtransform.c (_XrTransformBoundingBox): Added support for | |
transforming a bounding box, (an axis-aligned rectangle prior to | |
transformation). The ShowImage support needs this. | |
(_XrTransformComputeInverse): Now catches error case for | |
non-invertible matrix. | |
* xrsurface.c (_XrSurfaceSetTransform): Fixed ordering of matrix | |
for call to RenderSetPictureTransform | |
* xrgstate.c (_XrGStateSetMatrix): | |
(_XrGStateIdentityMatrix): Support for new Xr matrix functions. | |
(_XrGStateShowImage): | |
(_XrGStateShowImageTransform): Fixed transformation of images. | |
* xr.c (XrSetMatrix): | |
(XrDefaultMatrix): | |
(XrIdentityMatrix): Added 3 matrix manipulation functions. | |
2002-11-04 Carl Worth <cworth@isi.edu> | |
* xrsurface.c (_XrSurfaceDereference): | |
(_XrSurfaceDereferenceDestroy): Fixed bug in reference counting | |
logic. | |
(_XrSurfaceSetDrawableWH): XrSurface now keeps track of its width/height. | |
(_XrSurfaceGetDrawable): | |
(_XrSurfaceGetWidth): | |
(_XrSurfaceGetHeight): | |
(_XrSurfaceGetDepth): New accessor functions. | |
* xrgstate.c (_XrGStateBeginGroup): | |
(_XrGStateEndGroup): Preliminary group support. Not too efficient | |
since it always composite's a full-size picture from child group | |
to parent picture, (even if only a small portion has | |
non-transparent pixels). | |
(_XrGStateShowImageTransform): Fixed show image to use current | |
alpha value. | |
* xrfont.c (_XrFontResolveXftFont): Fixed memory leak | |
(FcPatternDestroy). There's still some meory | |
leaking/left-reachable in Xft/fontconfig that I need to track | |
down. | |
* xr.c (XrPushGroup): | |
(XrPopGroup): Added preliminary group support. I think I like | |
having this in the API as it takes several burdens away from the | |
user, (plus it matches the PDF model). Things to do still: think | |
about the names of these functions. Re-read the PDF semantics to | |
see if we're missing anything. | |
2002-11-02 Carl Worth <cworth@isi.edu> | |
* xrsurface.c (_XrSurfaceSetImage): Fixed leak of the image | |
pixmap. | |
2002-11-01 Carl Worth <cworth@east.isi.edu> | |
* xrsurface.c (_XrSurfaceSetImage): Prelimary image | |
support. Really only works with ARGB32. I still need to think | |
about what formats will be supported. | |
(_XrSurfaceSetTransform): Partial support for transformed | |
surfaces. | |
(_XrSurfaceGetXcSurface): Moved all creation/destruction of the | |
XcSurface into this function so that it is only lazily created | |
when needed. | |
* xrgstate.c (_XrGStateSetCurrentPt): gstate now can throw errors | |
when an operation needs current point, but it doesn't exist yet. | |
(_XrGStateShowImage, _XrGStateShowImageTransform): Preliminary | |
image support, (currently it only scales according to the CTM. The | |
matrix passed with the image doesn't do anything yet.) | |
* xrfont.c (_XrFontInitCopy): Removed bogus out of memory errors. | |
* xr.c (XrShowImage, XrShowImageTransform): Added very preliminary | |
image support. Things don't work completely yet and all the | |
interfaces are likely to change. | |
(XrGetStatusString): Added function to map status values to strings. | |
2002-10-31 Carl Worth <cworth@isi.edu> | |
* xrfont.c (_XrFontInit): | |
(_XrFontInitCopy): | |
(_XrFontDeinit): | |
(_XrFontSelect): | |
(_XrFontResolveXftFont): Updated by ripping all font support from | |
Xc and just putting a couple of calls to Xft and fontconfig right | |
here in xrfont. | |
* xr.c (XrTextExtents): Added XrTextExtents. | |
2002-10-29 Carl Worth <cworth@east.isi.edu> | |
* xrgstate.c (_XrGStateSelectFont, _XrGStateScaleFont) | |
(_XrGStateTransformFont, _XrGStateShowText): Added basic font | |
support. | |
* xr.c (XrSelectFont, XrScaleFont, XrTransformFont): Added basic | |
font support. | |
2002-10-28 Carl Worth <cworth@east.isi.edu> | |
* xrstate.c (_XrStatePop): Added error case for XrRestore without | |
matching XrSave. | |
* xrsurface.c (_XrSurfaceInit, _XrSurfaceReference) | |
(_XrSurfaceDereference): Added reference counting to XrSurface to | |
patch a memory leak. | |
2002-10-26 Carl Worth <cworth@isi.edu> | |
* xrtransform.c (_XrTransformDistance): | |
(_XrTransformPoint): changed to use individual X/Y arguments | |
rather tha an XPointDouble. This improves readability since | |
_XrTransformDistance is now always called with arguments of dx/dy | |
rather than pt.x/pt.y. | |
* xrpath.c (_XrPathMoveTo): | |
(_XrPathLineTo): | |
(_XrPathCurveTo): | |
(_XrPathClosePath): replaced public _XrPathAdd with explicit named | |
functions. This cleans up the implementation since _XrPathAdd, | |
which is unsafe with respect to argument consistency, is now | |
private. Also, since the _XrGState now maintains the current | |
point, I dropped all relative path operators from the XrPath data | |
structures. | |
* xrgstate.c (_XrGStateMoveTo): | |
(_XrGStateLineTo): | |
(_XrGStateCurveTo): | |
(_XrGStateRelMoveTo): | |
(_XrGStateRelLineTo): | |
(_XrGStateRelCurveTo): Replaces _XrGStateAddPathOp and | |
_XrGStateAddUnaryPathOp with explicit named functions for each | |
operator type. This change introduces the current point state into | |
the XrGState structure rather than postponing its calculation | |
until path interpretation. | |
* xrgstate.c (_XrGStateSetDrawable): | |
(_XrGStateSetVisual): | |
(_XrGStateSetFormat): | |
(_XrGStateSetOperator): | |
(_XrGStateSetRGBColor): | |
(_XrGStateSetTolerance): | |
(_XrGStateSetAlpha): | |
(_XrGStateSetFillRule): | |
(_XrGStateSetLineWidth): | |
(_XrGStateSetLineCap): | |
(_XrGStateSetLineJoin): | |
(_XrGStateSetMiterLimit): | |
(_XrGStateTranslate): | |
(_XrGStateScale): | |
(_XrGStateRotate): | |
(_XrGStateConcatMatrix): | |
(_XrGStateNewPath): : Added XrStatus return values to many | |
functions -- just for consistency, these functions can not return | |
errors in any case. | |
* xr.c (XrShowText): Started to ass XrShowText, (still not functional) | |
2002-10-24 Carl Worth <cworth@isi.edu> | |
* xr.c (XrSetFillRule): Added support to set fill rule. | |
2002-10-23 Carl Worth <cworth@isi.edu> | |
* xrtraps.c (_XrTrapsTessellatePolygon): Fix for polygon with | |
multiple sub-polygons that are disjoint in Y. | |
2002-07-16 Carl Worth <cworth@isi.edu> | |
* Xr.h: Renamed xrpicture.c to xrsurface.c as part of the move. | |
Added XrSetFormat, XrSetOperator, XrSetLineCap, XrSetLineJoin, and | |
XrSetMiterLimit, (although the line style drawing code is not all | |
in place yet). | |
* xrpath.c (XrPathLineTo): Changed LineTo semantics to be the same | |
as MoveTo if there was no previous MoveTo. | |
* xrtraps.c: Added tessellation code, (lifted from | |
XRenderCompositeDoublePoly which can now disappear). | |
* xrgstate.c: Changed stroke code to incrementally build a list of | |
trapezoids rather than forming one giant polygonal outline and | |
rendering that. This should be more efficient. | |
(_XrGStateFillPath): Now uses Xr's own tessellation along with | |
XcCompositeTrapezoids. | |
* Xr.h: Moved all of Xr away from Xrender to the new Xc library. | |
* xrsurface.c: Renamed from xrpicture.c, (part of the move from | |
XRender to Xc). | |
* Started keeping a ChangeLog ;-) | |
