Codec.Picture.Bitmap
Description
Modules used for Bitmap file (.bmp) file loading and writing
- writeBitmap :: BmpEncodable pixel => FilePath -> Image pixel -> IO ()
- encodeBitmap :: forall pixel. BmpEncodable pixel => Image pixel -> ByteString
- encodeBitmapWithMetadata :: forall pixel. BmpEncodable pixel => Metadatas -> Image pixel -> ByteString
- decodeBitmap :: ByteString -> Either String DynamicImage
- decodeBitmapWithMetadata :: ByteString -> Either String (DynamicImage, Metadatas)
- encodeDynamicBitmap :: DynamicImage -> Either String ByteString
- encodeBitmapWithPaletteAndMetadata :: forall pixel. BmpEncodable pixel => Metadatas -> BmpPalette -> Image pixel -> ByteString
- writeDynamicBitmap :: FilePath -> DynamicImage -> IO (Either String Bool)
- class BmpEncodable pixel
Functions
writeBitmap :: BmpEncodable pixel => FilePath -> Image pixel -> IO () Source #
Write an image in a file use the bitmap format.
encodeBitmap :: forall pixel. BmpEncodable pixel => Image pixel -> ByteString Source #
Encode an image into a bytestring in .bmp format ready to be written on disk.
encodeBitmapWithMetadata :: forall pixel. BmpEncodable pixel => Metadatas -> Image pixel -> ByteString Source #
Equivalent to encodeBitmap but also store
the following metadatas:
decodeBitmap :: ByteString -> Either String DynamicImage Source #
Try to decode a bitmap image. Right now this function can output the following image:
decodeBitmapWithMetadata :: ByteString -> Either String (DynamicImage, Metadatas) Source #
Same as decodeBitmap but also extracts metadata.
encodeDynamicBitmap :: DynamicImage -> Either String ByteString Source #
Encode a dynamic image in BMP if possible, supported images are:
encodeBitmapWithPaletteAndMetadata :: forall pixel. BmpEncodable pixel => Metadatas -> BmpPalette -> Image pixel -> ByteString Source #
writeDynamicBitmap :: FilePath -> DynamicImage -> IO (Either String Bool) Source #
Write a dynamic image in a .bmp image file if possible.
The same restriction as encodeDynamicBitmap apply.
Accepted format in output
class BmpEncodable pixel Source #
All the instance of this class can be written as a bitmap file using this library.
