Description

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) Source #

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

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

Equivalent to `readImage` but also providing metadatas.

decodeImage :: ByteString -> Either String DynamicImage Source #

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) Source #

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

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

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 Source #

`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)

dynamicMap :: (forall pixel. Pixel pixel => Image pixel -> a) -> DynamicImage -> a Source #

Helper function to help extract information from dynamic image. To get the width of a dynamic image, you can use the following snippet:

    dynWidth :: DynamicImage -> Int
    dynWidth img = dynamicMap imageWidth img

dynamicPixelMap :: (forall pixel. Pixel pixel => Image pixel -> Image pixel) -> DynamicImage -> DynamicImage Source #

Equivalent of the `pixelMap` function for the dynamic images. You can perform pixel colorspace independant operations with this function.

For instance, if you want to extract a square crop of any image, without caring about colorspace, you can use the following snippet.

    dynSquare :: DynamicImage -> DynamicImage
    dynSquare = dynamicPixelMap squareImage

    squareImage :: Pixel a => Image a -> Image a
    squareImage img = generateImage (\x y -> pixelAt img x y) edge edge
       where edge = min (imageWidth img) (imageHeight img)

generateImage Source #

Arguments

:: forall px. Pixel px |
=> (Int -> Int -> px) | Generating function, with `x` and `y` params.
-> Int | Width in pixels
-> Int | Height in pixels
-> Image px |

Create an image given a function to generate pixels. The function will receive values from 0 to width-1 for the x parameter and 0 to height-1 for the y parameter. The coordinates 0,0 are the upper left corner of the image, and (width-1, height-1) the lower right corner.

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 Source #

Arguments

:: forall a acc. Pixel a |
=> (acc -> Int -> Int -> (acc, a)) | Function taking the state, x and y
-> acc | Initial state
-> Int | Width in pixels
-> Int | Height in pixels
-> (acc, Image a) |

Create an image given a function to generate pixels. The function will receive values from 0 to width-1 for the x parameter and 0 to height-1 for the y parameter. The coordinates 0,0 are the upper left corner of the image, and (width-1, height-1) the lower right corner.

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 Source #

Arguments

:: forall m pixel. (Pixel pixel, PrimMonad m) |
=> Int | Image width
-> Int | Image height
-> (Int -> Int -> m pixel) | Generating functions
-> m (Image pixel) |

Uniform | Very fast algorithm (one pass), doesn't provide good looking results.

data PaletteOptions Source #

To specify how the palette will be created.

Constructors

PaletteOptions |

Fields

- paletteCreationMethod :: PaletteCreationMethod

  Algorithm used to find the palette

- enableImageDithering :: Bool

  Do we want to apply the dithering to the image. Enabling it often reduce compression ratio but enhance the perceived quality of the final image.

- paletteColorCount :: Int

  Maximum number of color we want in the palette

palettize :: PaletteOptions -> Image PixelRGB8 -> (Image Pixel8, Palette) Source #

Reduces an image to a color palette according to `PaletteOptions` and returns the indices image along with its `Palette`.

# Image types and pixel types

## Image

data Image a Source #

The main type of this package, one that most functions work on, is Image.

Parameterized by the underlying pixel format it forms a rigid type. If you wish to store images of different or unknown pixel formats use `DynamicImage`.

Image is essentially a rectangular pixel buffer of specified width and height. The coordinates are assumed to start from the upper-left corner of the image, with the horizontal position first and vertical second.

Constructors

Image |

Fields

- imageWidth :: !Int

  Width of the image in pixels

- imageHeight :: !Int

  Height of the image in pixels.

- imageData :: Vector (PixelBaseComponent a)

  Image pixel data. To extract pixels at a given position you should use the helper functions.

  Internally pixel data is stored as consecutively packed lines from top to bottom, scanned from left to right within individual lines, from first to last color component within each pixel.

## Pixels

class (Storable (PixelBaseComponent a), Num (PixelBaseComponent a), Eq a) => Pixel a where Source #

Definition of pixels used in images. Each pixel has a color space, and a representative component (Word8 or Float).

Minimal complete definition

mixWith, pixelOpacity, componentCount, colorMap, pixelAt, readPixel, writePixel, unsafePixelAt, unsafeReadPixel, unsafeWritePixel

Associated Types

type PixelBaseComponent a :: * Source #

Type of the pixel component, "classical" images would have Word8 type as their PixelBaseComponent, HDR image would have Float for instance

Methods

mixWith :: (Int -> PixelBaseComponent a -> PixelBaseComponent a -> PixelBaseComponent a) -> a -> a -> a Source #

Call the function for every component of the pixels. For example for RGB pixels mixWith is declared like this:

    mixWith f (PixelRGB8 ra ga ba) (PixelRGB8 rb gb bb) =
       PixelRGB8 (f 0 ra rb) (f 1 ga gb) (f 2 ba bb)

mixWithAlpha Source #

Arguments

:: (Int -> PixelBaseComponent a -> PixelBaseComponent a -> PixelBaseComponent a) | Function for color component
-> (PixelBaseComponent a -> PixelBaseComponent a -> PixelBaseComponent a) | Function for alpha component
-> a |
-> a |
-> a |

Extension of the `mixWith` which separate the treatment of the color components of the alpha value (transparency component). For pixel without alpha components, it is equivalent to mixWith.

    mixWithAlpha f fa (PixelRGBA8 ra ga ba aa) (PixelRGB8 rb gb bb ab) =
       PixelRGBA8 (f 0 ra rb) (f 1 ga gb) (f 2 ba bb) (fa aa ab)

pixelOpacity :: a -> PixelBaseComponent a Source #

Return the opacity of a pixel, if the pixel has an alpha layer, return the alpha value. If the pixel doesn't have an alpha value, return a value representing the opaqueness.

componentCount :: a -> Int Source #

Return the number of components of the pixel

colorMap :: (PixelBaseComponent a -> PixelBaseComponent a) -> a -> a Source #

Apply a function to each component of a pixel. If the color type possess an alpha (transparency channel), it is treated like the other color components.

pixelBaseIndex :: Image a -> Int -> Int -> Int Source #

Calculate the index for the begining of the pixel

mutablePixelBaseIndex :: MutableImage s a -> Int -> Int -> Int Source #

Calculate theindex for the begining of the pixel at position x y

pixelAt :: Image a -> Int -> Int -> a Source #

Extract a pixel at a given position, (x, y), the origin is assumed to be at the corner top left, positive y to the bottom of the image

readPixel :: PrimMonad m => MutableImage (PrimState m) a -> Int -> Int -> m a Source #

Same as pixelAt but for mutable images.

writePixel :: PrimMonad m => MutableImage (PrimState m) a -> Int -> Int -> a -> m () Source #

Write a pixel in a mutable image at position x y

unsafePixelAt :: Vector (PixelBaseComponent a) -> Int -> a Source #

Unsafe version of pixelAt, read a pixel at the given index without bound checking (if possible). The index is expressed in number (PixelBaseComponent a)

unsafeReadPixel :: PrimMonad m => STVector (PrimState m) (PixelBaseComponent a) -> Int -> m a Source #

Unsafe version of readPixel, read a pixel at the given position without bound checking (if possible). The index is expressed in number (PixelBaseComponent a)

unsafeWritePixel :: PrimMonad m => STVector (PrimState m) (PixelBaseComponent a) -> Int -> a -> m () Source #

Unsafe version of writePixel, write a pixel at the given position without bound checking. This can be _really_ unsafe. The index is expressed in number (PixelBaseComponent a)
