Main module for image import/export into various image formats.

To use the library without thinking about it, look after decodeImage and readImage.

Generally, the read* functions read the images from a file and try to decode it, and the decode* functions try to decode a bytestring.

For an easy image writing use the saveBmpImage, saveJpgImage & savePngImage functions

Generic functions

readImage :: FilePath -> IO (Either String DynamicImage)

Load an image file without even thinking about it, it does everything as decodeImage

readImageWithMetadata :: FilePath -> IO (Either String (DynamicImage, Metadatas))

Equivalent to readImage but also providing metadatas.

decodeImage :: ByteString -> Either String DynamicImage

If you want to decode an image in a bytestring without even thinking in term of format or whatever, this is the function to use. It will try to decode in each known format and if one decoding succeeds, it will return the decoded image in it's own colorspace.

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

Equivalent to decodeImage, but also provide potential metadatas present in the given file.

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

Equivalent to decodeImage, but also provide potential metadatas present in the given file and the palettes if the format provides them.

pixelMap :: forall a b. (Pixel a, Pixel b) => (a -> b) -> Image a -> Image b

map equivalent for an image, working at the pixel level. Little example : a brightness function for an rgb image

brightnessRGB8 :: Int -> Image PixelRGB8 -> Image PixelRGB8
brightnessRGB8 add = pixelMap brightFunction
     where up v = fromIntegral (fromIntegral v + add)
           brightFunction (PixelRGB8 r g b) =
                   PixelRGB8 (up r) (up g) (up b)

generateImage

Arguments

:: Pixel px

=> (Int -> Int -> px)

Generating function, with x and y params.

-> Int

Width in pixels

-> Int

Height in pixels

-> Image px

for example, to create a small gradient image:

imageCreator :: String -> IO ()
imageCreator path = writePng path $ generateImage pixelRenderer 250 300
   where pixelRenderer x y = PixelRGB8 (fromIntegral x) (fromIntegral y) 128

generateFoldImage

the acc parameter is a user defined one.

The function is called for each pixel in the line from left to right (0 to width - 1) and for each line (0 to height - 1).

withImage

Arguments

:: (Pixel pixel, PrimMonad m)

=> Int

Image width

-> Int

Image height

-> (Int -> Int -> m pixel)

Generating functions
