I have some images stored in ARGB (32-bit) format. While setting up "SkColorType" in "SkImageInfo" I do not see a corresponding 32-bit ARGB format there. Converting this buffer is going to be very expensive considering these images can be huge. Is there a way to avoid having to do this on the CPU on client side and can be handled within skia?

kBGRA_8888_SkColorType


This is ARGB in little-endian. Is that sufficient? If not, you may need to convert up-front, or use something like a SkColorMatrixFilter to swizzle when the image is sampled at runtime.
