##

Describes how to interpret the alpha component of a pixel.

#Const kUnknown_SkAlphaType 0
##
#Const kOpaque_SkAlphaType 1
All pixels are stored as opaque.
##
#Const kPremul_SkAlphaType 2
All pixels have their alpha premultiplied in their color components.
This is the natural format for the rendering target pixels.
##
#Const kUnpremul_SkAlphaType 3
All pixels have their color components stored without any regard to the
alpha. e.g. this is the default configuration for PNG images.
kUnpremul_SkAlphaType is supported only for input images. Rendering cannot
generate this on output.

Describes how to interpret the components of a pixel.

kN32_SkColorType selects the native 32-bit Color_ARGB format. On Little_Endian
processors, pixels containing 8-bit Color_ARGB components pack into 32-bit
kBGRA_8888_SkColorType. On Big_Endian processors, pixels pack into 32-bit
kRGBA_8888_SkColorType.
