fbarchard@google.com 4e78b8dc2e scale to 3/4 or 3/8 with odd width destinations efficiently. previously if width was not multiple of what the simd loop would do (24), scaling would fall back on slower C code. This change allows SIMD to be used for most of the scaling and C for the remainder, improving efficiency.

unit_test make box filter upsampler consider a pixel width of less than 1 to be 1. This makes it behave as a point sampler. 2015-04-16 21:02:16 +00:00
util clangcl build fix for __cpuid in psnr util. Since clangcl provides the intrinsic thru its Visual C emulation, don't duplicately define the function with an inline version, which is normally needed for gcc/clang. 2015-03-16 19:56:41 +00:00
