Description

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

Synopsis

- decodeTga :: ByteString -> Either String DynamicImage
- decodeTgaWithMetadata :: ByteString -> Either String (DynamicImage, Metadatas)
- decodeTgaWithPaletteAndMetadata :: ByteString -> Either String (PalettedImage, Metadatas)
- class TgaSaveable a
- encodeTga :: TgaSaveable px => Image px -> ByteString
- writeTga :: TgaSaveable pixel => FilePath -> Image pixel -> IO ()

# Documentation

decodeTga :: ByteString -> Either String DynamicImage Source #

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) Source #

Equivalent to decodeTga but also provide metadata

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

Equivalent to decodeTga but with metdata and palette if any

class TgaSaveable a Source #

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