Documentation

data BitmapImageString

Container for a string that represents a sequence of raw pixels lacking the alpha component and that is stored upside down

Constructors

forall s . StringCells s => BitmapImageString

Fields

_polyval_bitmapImageString :: s

Instances

Eq BitmapImageString

data BitmapStringRGB24A4VR

A bitmap represented as a string

This is essentially the format of pixels in the BMP format in which each row is aligned to a four-byte boundry and each row contains a series of RGB pixels.

This type is most efficient for programs interacting heavily with BMP files.
