Documentation
decodeTiff :: ByteString -> Either String DynamicImage #
Decode a tiff encoded image while preserving the underlying pixel type (except for Y32 which is truncated to 16 bits).
This function can output the following images:
decodeTiffWithMetadata :: ByteString -> Either String (DynamicImage, Metadatas) #
Like decodeTiff but also provides some metdata present
in the Tiff file.
The metadata extracted are the DpiX &
DpiY information alongside the EXIF informations.
decodeTiffWithPaletteAndMetadata :: ByteString -> Either String (PalettedImage, Metadatas) #
Decode TIFF and provide separated palette and metadata
class Pixel px => TiffSaveable px #
Class defining which pixel types can be serialized in a Tiff file.
Minimal complete definition

encodeTiff :: forall px. TiffSaveable px => Image px -> ByteString #
Transform an image into a Tiff encoded bytestring, ready to be written as a file.
