Enumeration Type Documentation

SkColorType

enum SkColorType : int

Describes how pixel bits encode color. A pixel may be an alpha mask, a grayscale, RGB, or ARGB.

kN32_SkColorType selects the native 32-bit ARGB format for the current configuration. This can lead to inconsistent results across platforms, so use with caution.
