Also, do add_point on newly - inserted intersection point. - -2001-10-14 Raph Levien - - * art_svp_intersect.c (art_svp_intersect_add_point): Fixed - rather subtle logic bug that misplaced insertion point - when seg argument was NULL. - -2001-10-11 Raph Levien - - * art_svp_render_aa.c (art_svp_render_aa_iter_step): Got rid - of qsort of steps, and now keep the step list in sorted order. - Further, we combine duplicate steps with the same x value, - which bounds the size of the step list to x1 - x0, so we - don't need to dynamically resize it. Thanks greatly to - Bruce Q.

Quite a bit of the code - feels like "reference code" now, in that it is (hopefully) - correct, but not necessarily very fast. In addition, there remain - a few things not done, including the use of SVP's as non-driver - mask sources. AlphaGamma and filter level also remain - unimplemented.

Thanks to Morten Welinder for spotting both of these - problems. - -2000-04-05 Raph Levien - - * art_svp_wind.c: Make "colinear" warnings go to stderr instead - of stdout.

(raph: i think flags is more generic - than free_pixels, so we can reuse that field if further demands popup - in the future). - - * art_pixbuf.c: - (art_pixbuf_new_const_rgba): - (art_pixbuf_new_const_rgb): new functions that prevent the pixels - member from being freed upon art_pixbuf_free (). - (art_pixbuf_free): only free the pixels member if it is non-NULL and - the PIXBUF_FLAG_DESTROY_PIXELS is set. - -1999-07-02 Raph Levien - - * art_vpath_bpath.c (art_vpath_render_bez): Bad bad uninitialized - variables. - - * configure.in: added compile warnings.

Thanks lewing! - -Wed Jun 23 11:16:42 1999 Raph Levien - - * art_rgb_svp.c: Made these routines so they won't segfault even - if alpha is out of range.

I somehow missed the fact that - a clockwise path should be given a winding number of zero; - last night's commit tried to make it -1 (which worked for the - test cases I was using). - -Sun Jun 13 01:23:14 1999 Raph Levien - - * art_svp_wind.c (art_svp_rewind_uncrossed): Change to winding - rule logic so that it correctly handles the case where the - leftmost segment is negative. - - * Makefile.am (libart_lgplinc_HEADERS): made art_svp_wind.h - a public headerfile.

It is now - consistent with the other header files. - -Wed Jun 9 20:24:45 1999 Raph Levien - - * art_svp_vpath_stroke.c: Added all remaining line join and cap - types, including round, which takes flatness into account. Several - new internal functions (art_svp_vpath_stroke_arc) and added - flatness argument to a few internal functions. I might want to - change the BEVEL join type to MITER for very small turn angles - (i.e. within a flatness threshold) for efficiency. - - * art_misc.h: Added M_SQRT2 constant. - -Wed Jun 2 21:56:30 1999 Raph Levien - - * art_svp_vpath_stroke.c (art_svp_vpath_stroke_raw): Made the - closed path detection capable of PostScript semantics (i.e. it - now senses the difference between ART_MOVETO and ART_MOVETO_OPEN). - - * art_svp_vpath_stroke.c (art_svp_vpath_stroke_raw): it now - filters out successive points that are (nearly) coincident. This - fixes some of the crashes and hangs, including Tim Janik's - singularity (trying to stroke MOVETO 50, 50; LINETO 50, 50; END). - - * art_svp_wind.c (art_svp_rewind_uncrossed): added a test to - correctly handle empty input svp's. - - * art_svp_wind.c (art_svp_uncross): added a test to correctly - handle empty input svp's. - -Sun Jan 17 20:53:40 1999 Jeff Garzik - - * art_affine.c: - Include string.h for memcpy. - - * art_svp_vpath.c: - Remove conflicting static func definition. - - * art_uta_svp.c: - Include art_vpath_svp.h for func definition. - -Mon Jan 4 12:47:47 1999 Raph Levien - - * art_bpath.c (art_bpath_affine_transform): Stupid misnaming - of this function (forgot the "art_"). - -Thu Dec 31 09:04:23 1998 Raph Levien - - * art_affine.c (art_affine_rectilinear): Added this function. - - * art_rect.c (art_drect_affine_transform): Corrected the name (it - was right in the .h).

Especially check the functions that generate - concise PostScript strings for affine transforms. - - * art_filterlevel.h: A simple enum for selecting filtering - style. - - * art_rgb_affine.h: - * art_rgb_affine.c (art_rgb_affine): Added. This function - composites an (opaque) rgb image over an rgb pixel buffer. At - present, it's slow and only nearest neighbor filtering is enabled. - - * art_rgb_rgba_affine.h: - * art_rgb_rgba_affine.c: Analogous, but for compositing rgba - images. - - * art_rgb_bitmap_affine.h: - * art_rgb_bitmap_affine.c: Analogous, but for compositing bitmap - images. - - * art_rgb_affine_private.c (art_rgb_affine_run): Added. This is - a common function used by all the rgb_affine modules to move - testing for source image bbox out of the inner loop. - - * Makefile.am: added the new files - - * testart.c: exercise the image compositors - -Wed Dec 9 23:36:35 1998 Raph Levien - - * art_vpath.c (art_vpath_perturb): Made it deal correctly - with closed paths (the MOVETO and closing LINETO have to - agree). - - * art_svp_wind.c: Made the bbox calculations for the resulting - svp's correct. - - * art_svp.h: - * art_svp.c: The art_svp_seg_compare function moved here, because - it's required in art_svp_ops. - - * art_svp.c (art_svp_add_segment): It now does bbox calculations. - - * art_svp_ops.h: - * art_svp_ops.c: Added. Populated with basic union, intersection, - and diff functions. - - * art_vpath_svp.h: - * art_vpath_svp.c: Added. Populated with a function to convert - from sorted to unsorted vector paths - - * Makefile.am: added the new files - - * testart.c: exercise the stroke outline and vector path - operations. - -1998-12-08 Herbert Valerio Riedel - - * art_svp_wind.c: added #include for memcpy() - -Sun Dec 6 22:15:12 1998 Raph Levien - - * art_svp_wind.[ch], art_svp_vpath_stroke.[ch]: Added, but it - doesn't work yet. These will do stroke outline and basic - vector ops like union, intersect, etc. - - * art_svp_render_aa.c: Added a simple speedup based on bbox - culling. I will want to do more speedups, but none of this is - necessary for the freeze. - - * art_svp_vpath.c: Fixed some bugs in the art_svp_from_vpath in - cases where there is more than one subpath. - - * art_vpath.h: - * art_vpath.c (art_vpath_perturb): Added this function. This will - help cheat as long as the basic vector ops have numerical - stability problems. - -Fri Dec 4 18:00:38 1998 Raph Levien - - * art_svp_render_aa.c (art_svp_render_aa): Changed the api - slightly, to guarantee that the steps are all within the range - from x0 (inclusive) to x1 (exclusive). - - * art_gray_svp.c, art_gray_svp.h: Added. Populated with functions - to render into a simple graymap. - - * art_rgb.c, art_rgb.c: Added. Populated with fill_run and - run_alpha methods. - - * art_rgb_svp.c, art_rgb_svp.h: Added. Populated with functions to - render into an RGB buffer, and to composite over an RGB buffer. - - * Makefile.am: added art_gray_svp, art_rgb, and art_rgb_svp. - - * testart.c: test the color and layered rendering. - -Mon Nov 30 01:30:25 1998 Raph Levien - - * testart.c: added vector path rendering stuff. Some of it needs - to go out of the test framework and into the module, but the - api hasn't settled down entirely yet (in the real code, all - x's in the step field are within bounds). - - * art_svp_render_aa.c, art_svp_render_aa.c.h: added. - - * art_svp_vpath.c, art_svp_vpath.h: added. - - * art_pathcode.h: added ART_MOVETO_OPEN (libart uses an - ART_MOVETO_OPEN code at the beginning to indicate an open path, - while PostScript uses the lack of a closepath at the end). - - * art_vpath_bpath.c, art_vpath_bpath.h: fixed it up, added - flatness arg to api. - - * Makefile.am: added new source files. - -Wed Nov 25 17:19:44 1998 Raph Levien - - * art_svp.h, art_svp.c: added, basic constructors for sorted - vector paths. - -Sun Nov 22 23:21:09 1998 Raph Levien - - * Makefile.am (libart_lgplincdir): Fixed stupid bug in naming of - the variable. - -Sun Nov 22 21:41:13 1998 Raph Levien - - * art_uta_vpath.c: moved art_uta_union into art_uta_ops. - - * art_uta_ops.[ch]: added, populated with art_uta_union. - -Thu Nov 19 00:19:40 1998 Raph Levien - - * libartConf.sh.in: added - - * Makefile.am: added creation of libartConf.sh, added -version-info - * configure.in: added LIBART_VERSION_INFO, support for libartConf.sh - - * libart.m4: updated version history :) - -Wed Nov 18 18:15:20 1998 Raph Levien - - * configure.in (LIBART_VERSION): set this, so that libart-config - --version now works. - -Wed Nov 18 16:50:58 1998 Raph Levien - - * libart.m4: added (just copied from esound) - * configure.in, Makefile.am: added support for libart-config - * libart-config.in: added (mostly copied from esound) - -Tue Nov 10 12:43:30 1998 Raph Levien - - * Getting the library in shape for initial checkin to CVS. - -
