Android plans to use 16-bit png to encode higher precision assets. This CL should not change any behavior or cause diffs on Gold. It simply moves the 16-bit -> 8-bit strip from libpng to SkSwizzler. As a follow-up, I plan to add support for 16-bit input to SkColorSpaceXform. This will require a new swizzler function that just samples or subsets 16-bit values (but does not strip to 8-bit). An alternative implementation could avoid the additional swizzler functions by deciding whether or not to call png_set_strip() at decode time (we would still need the swizzler fn to sample/subset 16-bit values). I find this strategy to be cleaner than that. I would rather handle 16-bit rgb(a) all the time than *some* of the time. And this is implementation is also more efficient than libpng. Though it is also more skia code. Gray and gray alpha are left alone until I know whether anyone wants high precision gray support. b/32984164 Change-Id: I44e307473526de3f4bba06879c5fffa25d480f56 Reviewed-on: https://skia-review.googlesource.com/6020 Reviewed-by: Leon Scroggins <scroggo@google.com> Commit-Queue: Matt Sarett <msarett@google.com> |
