Hello, Patch in attach add SIMD for the 5 shuffle_bytes func for rgb2rgb The new SIMD are write using external ASM.
Also add checkasm test for theses func Restricted to x86_64, because the scalar part doesn't compile on x86_32 I consider for the scalar part that the src_size value is a multiple of 4 (because the shuffle is for 4 bytes) Pass fate test on X86_64 and X86_32 (os 10.12) Martin
