2010-06-03draw.Draw fast paths for the Over operator.Nigel Tao1-34/+93
Time (us) to draw a 200x200 src onto an image.RGBA dst with the Over operator. Each case was measured three separate times, and the sorted times are reported. Fill case (where src is an image.ColorImage): Before: 7438, 7511, 7526 After: 3073, 3087, 3102 Copy case (where src is an image.RGBA): Before: 9506, 9510, 9563 After: 5262, 5300, 5344 R=rsc CC=golang-dev http://codereview.appspot.com/1532041

2010-05-20Fast-ish path for drawing onto an image.RGBA destination.Nigel Tao2-13/+121
Time to draw.Draw a 200x200 image fell from 18.4ms (and 1 malloc) to 5.6ms (and 0 mallocs). It's still relatively slow since it assumes nothing about the src or mask images, but it does remove the malloc. There are existing faster, more specialized paths for copies, fills and image glyph masks. Also added a "compare to a slow but obviously correct implementation" check to draw_test.go.

2010-02-06draw.Draw fast paths for a nil mask (and RGBA dst).Nigel Tao1-0/+50
Averaged times (in microseconds) for drawing an 800x600 rectangle are listed below. The summary is: around a 100x improvement. draw.Draw call times were typically linear in the number of pixels touched (i.e. drawing an 800x600 rectangle took 100x as much time as drawing an 80x60 rectangle). Before this change, there was only the general-but-slow code path. When drawing any src with a 50%-opaque mask: 237300 us When drawing any src with a nil mask: 50100 us After this change, the 50%-opaque mask case is unchanged. For an *image.RGBA dst and nil mask and... ...a uniform color (i.e. an image.ColorImage) src: 282 us ...another *image.RGBA src: 615 us. For the curious, an intermediate implementation detected the special cases but used simple nested for loops instead of the built-in copy function. The respective times (compared to 282 and 615 for the final implementation, or 50100 for the original) were 3110 and 3573. Times were measured with 8g/8l on my laptop. I haven't tried gccgo or other architectures. R=r, rsc CC=golang-dev http://codereview.appspot.com/201048
