blockSize

Used to assist with allocating memory for pixel formats that don’t have an integer value for bytes per pixel. Block width/height is essentially the width/height in pixels of the smallest “byte addressable” group of pixels. This works in close conjunction with Bitsperblock. Examples: 8-bit luminance only, blockSize.width would be 1, bitsPerBlock would be 8 16-bit 1555 RGB, blockSize.width would be 1, bitsPerBlock would be 16 32-bit 8888 ARGB, blockSize.width would be 1, bitsPerBlock would be 32 2vuy (CbYCrY), blockSize.width would be 2, bitsPerBlock would be 32 1-bit bitmap, blockSize.width would be 8, bitsPerBlock would be 8 v210, blockSize.width would be 6, bitsPerBlock would be 128
