Codec.Picture.Tga

Module implementing function to read and write Targa (*.tga) files.

Documentation

decodeTga :: ByteString -> Either String DynamicImage

Transform a raw tga image to an image, without modifying the underlying pixel type.

This function can output the following images:

• ImageY8
• ImageRGB8
• ImageRGBA8

decodeTgaWithMetadata :: ByteString -> Either String (DynamicImage, Metadatas)

Equivalent to decodeTga but also provide metadata

decodeTgaWithPaletteAndMetadata :: ByteString -> Either String (PalettedImage, Metadatas)

Equivalent to decodeTga but with metdata and palette if any

class TgaSaveable a

This typeclass determine if a pixel can be saved in the TGA format.
