Detailed Description

Describes pixel dimensions and encoding.

SkBitmap, SkImage, PixMap, and SkSurface can be created from SkImageInfo. SkImageInfo can be retrieved from SkBitmap and SkPixmap, but not from SkImage and SkSurface. For example, SkImage and SkSurface implementations may defer pixel depth, so may not completely specify SkImageInfo.

SkImageInfo contains dimensions, the pixel integral width and height. It encodes how pixel bits describe alpha, transparency; color components red, blue, and green; and SkColorSpace, the range and linearity of colors.
