* Refactor resize filter to go fasterGravatar caryclark2016-01-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Part of this CL improves the speed by using dynamic arrays more effectively. Part uses SIMD and more concise float expressions for speed. Some unused code was deleted. The latter changes are guarded by: SK_SUPPORT_LEGACY_BITMAP_FILTER until this lands and the corresponding layout changes in chrome can be relanded. With the legacy flag defined, no Skia or Chrome test results change. Without the flag defined in Skia, only 0.01% - 0.02% of the pixels change, and then by (1,1,1) in 8888. codereview.chromium.org/1583533002 adds the guard to Chrome.

* Adding 64 bit checksGravatar sugoi2014-07-03
| | | | | | | | | | | | | Added a few more checks to avoid overflowing 32 bit sizes while computing convolutions. I also changed a dangerously misleading INHERITED typedef.

| | | | | | | | | | | | Last CL accidentally disabled autovectorization on 64-bit builds too. This fixes that. BUG=skia:2575 R=rmistry@google.com, mtklein@google.com Author: mtklein@chromium.org Review URL: https://codereview.chromium.org/353823005
* Support for larger than "signed 32b limit" sized bitmaps in BGRAConvolve2D.Gravatar sugoi2014-06-11
| | | | | | | | | | | The multiplication of 2 signed ints was producing a result larger than what's supported by a single signed int and the memory was accessed out of bounds. Using uint64_t solves the issue. BUG=378491 R=reed@google.com, rmistry@google.com Author: sugoi@chromium.org Review URL: https://codereview.chromium.org/323013005

* Manually set fFilterValues in SkConvolutionFilter1D.Gravatar commit-bot@chromium.org2014-03-06
| | | | | | | | | | | | | | | | Using fFilterValues.reset() or a loop of fFilterValues.push_back() is about 5x slower than calling fFilterValues.resize_back() and then looping using primitive [] and =. This is only going to show up if you apply https://codereview.chromium.org/183763047/, where it yields about 2.5% speedup in the bitmap resize microbenchmarks on a Linux desktop. Ceteris paribus, it should actually improve rasterization time of drawBitmapRectToRect() with a resize by about 5% in Chromium.
