Previously, non-AA quad edges only have an accuracy about 1/2 pixel (while the AA quad edges have an accuracy about 1/8 pixel). Now, we increase non-AA quad edges' accuracy to 1/8 pixel as well. The difference is very significant for rotating non-AA filled circles. For example, run `./out/Debug/SampleApp --slide GM:fillcircle` with AA turned off (by pressing b). The benchmark added reveals that increasing quad accuracy from 1/2 to 1/8 doesn't affect the performance significantly. The following is the 1/2-accuracy performance versus 1/8-accuracy performance: curr/maxrss loops min median mean max stddev samples config bench 7/17 MB 19 2.43µs 2.57µs 2.81µs 10.5µs 22% 16119 8888 path_fill_big_nonaacircle 7/17 MB 17 1.38µs 1.42µs 1.52µs 13µs 20% 21409 8888 path_fill_small_nonaacircle curr/maxrss loops min median mean max stddev samples config bench 7/17 MB 71 2.52µs 2.59µs 2.79µs 7.67µs 19% 7557 8888 path_fill_big_nonaacircle 7/17 MB 64 1.45µs 1.49µs 1.51µs 2.39µs 5% 12704 8888 path_fill_small_nonaacircle BUG=skia: Change-Id: I3482098aeafcc6f2ec9aa3382977c0dc1b650964 Reviewed-on: https://skia-review.googlesource.com/6699 Reviewed-by: Mike Reed <reed@google.com> Commit-Queue: Yuqian Li <liyuqian@google.com> |
