Synopsis

Functions

valuewriteBitmap :: BmpEncodable pixel => FilePath -> Image pixel -> IO ()

Write an image in a file use the bitmap format.

valueencodeBitmap :: BmpEncodable pixel => Image pixel -> ByteString

Encode an image into a bytestring in .bmp format ready to be written on disk.

valueencodeBitmapWithMetadata

Equivalent to encodeBitmap but also store the following metadatas:

valuedecodeBitmap :: ByteString -> Either String DynamicImage

Try to decode a bitmap image. Right now this function can output the following image:

valuedecodeBitmapWithMetadata

Same as decodeBitmap but also extracts metadata.

valuedecodeBitmapWithPaletteAndMetadata

Same as decodeBitmap but also extracts metadata and provide separated palette.

valueencodeDynamicBitmap :: DynamicImage -> Either String ByteString

Encode a dynamic image in BMP if possible, supported images are:

valueencodeBitmapWithPaletteAndMetadata

Equivalent to encodeBitmapWithPalette but also store the following metadatas:

valuewriteDynamicBitmap :: FilePath -> DynamicImage -> IO (Either String Bool)

Write a dynamic image in a .bmp image file if possible. The same restriction as encodeDynamicBitmap apply.

classclass BmpEncodable pixel where

All the instance of this class can be written as a bitmap file using this library.
