These components -- are also referred as \"channels\"; for example a color image could be made out -- of three channels, the red, green and blue one. The components can be unsigned -- bytes, words, dwords, or floats. The pixels are stored in horizontal order, -- and the channels are interleaved: That is, the structure of an RGB image is -- @R0 G0 B0 R1 G1 B1 ...@. -- Most of the library is indifferent to the meaning of different channels. -- -- \"Padding\" refers to unused bytes at the end of each row. This is sometimes -- necessary because other software components want the rows aligned to machine -- word boundary, for example. -- -- The library should be relatively fast (except where noted), but -- performance is not the primary goal (thus there is no inline assembly, -- no SSE, etc.; but the critical functions are coded in C). -- -- There are both pure and IO versions of the API; you shouldn't mix -- the two without taking special care. -- This module re-exports the pure interface; if you want the IO one, -- import 'Data.Bitmap.IO' instead. -- {-# LANGUAGE CPP, ForeignFunctionInterface, ScopedTypeVariables #-} module Data.Bitmap ( module Data.Bitmap.Pure ) where -------------------------------------------------------------------------------- import Data.Bitmap.Pure --------------------------------------------------------------------------------
