When tops + coincide, full ordering test is performed (with breaking), + rather than just comparing b from line eq. Also, had a test + for x >= backwards in art_svp_intersect_add_point. Thanks + to Bruce Q. Hammond for test cases. + +2001-11-21 Raph Levien <raph@pixel.artofcode.com> + + * art_svp_intersect.c (art_svp_intersect_break): Changed break + logic systematically so that new breaks are always in order, + rather than allowing them to become out of order, then try to fix + them up later. It's no doubt possible to come up with cases in + which this reduces precision, but it simplifies life nicely, so I + did it. + + * (art_svp_intersect_horiz): Initialize (a, b, c) values of hs to + avoid UMR's when they are tested later. + + * art_svp_ops.c (print_ps_vpath): Changed the coordinate + transform so that it's done in the PostScript rather than + the C code that outputs the coordinates. This makes it easier + to reconstruct the vector path from the debug output. + +2001-11-16 Alex Larsson <alexl@redhat.com> + + * art_rect.c (art_drect_svp_union, art_drect_svp): + Don't call art_drect_union() in these functions, since + it considers zero-width or zero-height svg segments to + be empty. This causes it to think i.e. rectangular svps + are empty. + +2001-11-07 Raph Levien <raph@pixel.artofcode.com> + + * art_svp_intersect.c (art_svp_intersect_horiz): Fixed important + logic bug, failing to test crossings of neighbors when inserting + horizontal lines. Also changed printf to art_dprint. + + * art_misc.c (art_dprint): Added function for debug printing, + so verbose intersector output doesn't have to go through printf. + + * art_misc.h (ART_USE_NEW_INTERSECTOR): I've turned this on + now, as the new intersector certainly seems to be performing + better than the old one now. + +2001-10-31 Anders Carlsson <andersca@gnu.org> + + * Release 2.3.7 + +2001-10-15 Raph Levien <raph@pixel.artofcode.com> + + * art_svp_intersect.c (art_svp_intersect_horiz): Minor + logic fix so that horiz segments successfully cross + zero length segments in the active list. + + (art_svp_intersect_test_cross): Flags indicating whether to + do add_point (potentially breaking neighbors) to left and + to right. + + (art_svp_intersect_insert_cross): Provide ART_BREAK_LEFT and + ART_BREAK_RIGHT flags to art_svp_intersect_test_cross, + depending on direction of search. + + (art_svp_intersect_advance_cursor): Provide flags (allow + both left and right breaking) to test_cross. + +2001-10-15 Raph Levien <raph@pixel.artofcode.com> + + * art_svp_intersect.c (CHEAP_SANITYCHECK): Added an inexpensive + sanitycheck to detect multiple insertions of a segment into the + horiz list. + + (art_svp_writer_rewind_add_point): Avoid breaking lines below + their bottom point. + + (art_svp_intersect_test_cross): Handle cases correctly where + intersection point matches y0 of left or right segment. These _do_ + happen in real world examples. Also, do add_point on newly + inserted intersection point. + +2001-10-14 Raph Levien <raph@pixel.artofcode.com> + + * 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 <raph@pixel.artofcode.com> + + * 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. Hammond for the original version of this patch. + +2001-10-09 Raph Levien <raph@pixel.artofcode.com> + + * art_svp_intersect.c (art_svp_intersect_test_cross): Breaks + bottom part of line segments in "too close" cases. + +2001-10-09 Raph Levien <raph@pixel.artofcode.com> + + * art_svp_intersect.c (art_svp_writer_rewind_add_point): Fixed + bbox computation. + (art_svp_intersector): Handle degenerate case where input + SVP has 0 segments. + + * art_svp_intersect.h: Moved definition of art_svp_intersector + inside #ifdef __cplusplus, so it links properly against C++ + +2001-10-09 Raph Levien <raph@pixel.artofcode.com> + + * art_svp_intersect.c (art_svp_intersect_break): Handle + case when break y equals sweep line correctly. Also adds + first try at winding number sanitychecker, but that makes + too many false positives. + +2001-10-07 Raph Levien <raph@pixel.artofcode.com> + + * art_svp.c (EPSILON): Set to zero if new intersector is + in use - we want svp's to be in strict sorted order. + + * art_svp_intersect.c (art_svp_intersect_test_cross): Explicitly + check that top points are equal, and swap immediately if b is out + of order. + (art_svp_intersect_horiz): Break segments that intersect + horizontal lines. Now passes "two squares with offset" test. + +2001-10-05 Raph Levien <raph@pixel.artofcode.com> + + * art_svp_intersect.c: Major changes to accommodate + horizontal lines. Intersections of horizontal lines + aren't fully processed, but should work a lot better + than before. + + * testart.c: Minor tweaks. testpat now frees memory + so it can be run under memprof to detect leaks. + +2001-10-03 Raph Levien <raph@pixel.artofcode.com> + + * art_svp_intersect.c (art_svp_intersect_advance_cursor): + Made test_cross for inserted segments common between + intersection processing and cursor advance, and also took + care of a case that hadn't been handled before. Also added + invariant sanitychecker for debugging purposes. + +2001-10-02 Raph Levien <raph@pixel.artofcode.com> + + * art_svp_ops.c: ART_USE_NEW_INTERSECTOR variants of svp + ops changed to do shallow free of merged svp. + +2001-10-01 Raph Levien <raph@acm.org> + + * art_svp_intersect.c: + * art_svp_intersect.h: + * Makefile.am: + * art_misc.h: + * art_svp_wind.h: First commit of new intersector code.

Thanks to Leonard Rosenthol for spotting + the bug. + +Fri Jun 30 22:56:58 2000 Raph Levien <raph@acm.org> + + * art_render.c (art_render_composite): Fixed a bug that caused + it to ignore the alpha setting.

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.
