# 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:

- `ImageY8`
- `ImageY16`
- `ImageYA8`
- `ImageYA16`
- `ImageRGB8`
- `ImageRGB16`
- `ImageRGBA8`
- `ImageRGBA16`
- `ImageCMYK8`
- `ImageCMYK16`

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.
