# Types

## Image types

data Image a #

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.

data MutableImage s a #

Image or pixel buffer, the coordinates are assumed to start from the upper-left corner of the image, with the horizontal position first, then the vertical one. The image can be transformed in place.

Constructors

MutableImage |
Fields mutableImageWidth :: !Int Width of the image in pixels mutableImageHeight :: !Int Height of the image in pixels. mutableImageData :: STVector s (PixelBaseComponent a) The real image, to extract pixels at some position you should use the helpers functions.

## Image functions

createMutableImage #

Arguments

:: (Pixel px, PrimMonad m) |
=> Int | Width
-> Int | Height
-> px | Background color
-> m (MutableImage (PrimState m) px) |

Create a mutable image, filled with the given background color.

newMutableImage #

Arguments

:: (Pixel px, PrimMonad m) |
=> Int | Width
-> Int | Height
-> m (MutableImage (PrimState m) px) |

Create a mutable image with garbage as content. All data is uninitialized.

freezeImage :: (Storable (PixelBaseComponent px), PrimMonad m) => MutableImage (PrimState m) px -> m (Image px) #

`O(n)` Yield an immutable copy of an image by making a copy of it

unsafeFreezeImage :: (Storable (PixelBaseComponent a), PrimMonad m) => MutableImage (PrimState m) a -> m (Image a) #

`O(1)` Unsafe convert a mutable image to an immutable one without copying. The mutable image may not be used after this operation.

thawImage :: (Storable (PixelBaseComponent px), PrimMonad m) => Image px -> m (MutableImage (PrimState m) px) #

`O(n)` Yield a mutable copy of an image by making a copy of it.

unsafeThawImage :: (Storable (PixelBaseComponent px), PrimMonad m) => Image px -> m (MutableImage (PrimState m) px) #

`O(1)` Unsafe convert an imutable image to an mutable one without copying. The source image shouldn't be used after this operation.

## Image Lenses

type Traversal s t a b = forall (f :: Type -> Type). Applicative f => (a -> f b) -> s -> f t #

Traversal type matching the definition in the Lens package.

imagePixels :: (Pixel pxa, Pixel pxb) => Traversal (Image pxa) (Image pxb) pxa pxb #

Traversal in "raster" order, from left to right the top to bottom. This traversal is matching pixelMap in spirit.

Since 3.2.4

imageIPixels :: (Pixel pxa, Pixel pxb) => Traversal (Image pxa) (Image pxb) (Int, Int, pxa) pxb #

Traversal providing the pixel position with it's value. The traversal in raster order, from lef to right, then top to bottom. The traversal match pixelMapXY in spirit.

Since 3.2.4

## Pixel types

type Pixel8 = Word8 #

Type alias for 8bit greyscale pixels. For simplicity, greyscale pixels use plain numbers instead of a separate type.

type Pixel16 = Word16 #

Type alias for 16bit greyscale pixels.

type Pixel32 = Word32 #

Type alias for 32bit greyscale pixels.

type PixelF = Float #

Type alias for 32bit floating point greyscale pixels. The standard bounded value range is mapped to the closed interval [0,1] i.e.

    map promotePixel [0, 1 .. 255 :: Pixel8] == [0/255, 1/255 .. 1.0 :: PixelF]

data PixelYA8 #

Pixel type storing 8bit Luminance (Y) and alpha (A) information. Values are stored in the following order:

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

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 #

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 #

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 #

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 #

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 #

Return the number of components of the pixel

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

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 #

Calculate the index for the begining of the pixel

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

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

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

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 #

Same as pixelAt but for mutable images.

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

Write a pixel in a mutable image at position x y

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

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 #

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 () #

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)

# Helper functions

pixelMap :: (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)

pixelMapXY :: (Pixel a, Pixel b) => (Int -> Int -> a -> b) -> Image a -> Image b #

Just like `pixelMap` only the function takes the pixel coordinates as additional parameters.

pixelFold :: forall acc pixel. Pixel pixel => (acc -> Int -> Int -> pixel -> acc) -> acc -> Image pixel -> acc #

Fold over the pixel of an image with a raster scan order: from top to bottom, left to right

pixelFoldM #

Arguments

:: (Pixel pixel, Monad m) |
=> (acc -> Int -> Int -> pixel -> m acc) | monadic mapping function
-> acc | Initial state
-> Image pixel | Image to fold over
-> m acc |

Fold over the pixel of an image with a raster scan order: from top to bottom, left to right, carrying out a state

pixelFoldMap :: forall m px. (Pixel px, Monoid m) => (px -> m) -> Image px -> m #

Fold over the pixel of an image with a raster scan order: from top to bottom, left to right. This functions is analog to the foldMap from the `Foldable` typeclass, but due to the Pixel constraint, Image cannot be made an instance of it.

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

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 #

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)

palettedToTrueColor :: PalettedImage -> DynamicImage #

Flatten a PalettedImage to a DynamicImage

palettedAsImage :: Palette' px -> Image px #

Convert a palette to an image. Used mainly for backward compatibility.

dropAlphaLayer :: TransparentPixel a b => Image a -> Image b #

For any image with an alpha component (transparency), drop it, returning a pure opaque image.

withImage #

Arguments

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

Create an image using a monadic initializer function. 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 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).

zipPixelComponent3 :: Storable (PixelBaseComponent px) => (PixelBaseComponent px -> PixelBaseComponent px -> PixelBaseComponent px -> PixelBaseComponent px) -> Image px -> Image px -> Image px -> Image px #

Combine, pixel by pixel and component by component the values of 3 different images. Usage example:

    averageBrightNess c1 c2 c3 = clamp $ toInt c1 + toInt c2 + toInt c3
      where clamp = fromIntegral . min 0 . max 255
            toInt :: a -> Int
            toInt = fromIntegral
    ziPixelComponent3 averageBrightNess img1 img2 img3

generateImage #

Arguments

:: 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 #

Arguments

:: 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).

gammaCorrection #

Arguments

:: PixelF | Gamma value, should be between 0.5 and 3.0
-> Image PixelRGBF | Image to treat.
-> Image PixelRGBF |

Perform a gamma correction for an image with HDR pixels.

toneMapping #

Arguments

:: PixelF | Exposure parameter
-> Image PixelRGBF | Image to treat.
-> Image PixelRGBF |

Perform a tone mapping operation on an High dynamic range image.

extractComponent :: (Pixel px, Pixel (PixelBaseComponent px), PixelBaseComponent (PixelBaseComponent px) ~ PixelBaseComponent px, ColorPlane px plane) => plane -> Image px -> Image (PixelBaseComponent px) #

Extract a color plane from an image given a present plane in the image examples:

     extractRedPlane :: Image PixelRGB8 -> Image Pixel8
     extractRedPlane = extractComponent PlaneRed

unsafeExtractComponent #

Arguments

:: (Pixel a, Pixel (PixelBaseComponent a), PixelBaseComponent (PixelBaseComponent a) ~ PixelBaseComponent a) |
=> Int | The component index, beginning at 0 ending at (componentCount - 1)
-> Image a | Source image
-> Image (PixelBaseComponent a) |

Extract a plane of an image. Returns the requested color component as a greyscale image.

If you ask for a component out of bound, the `error` function will be called.

# Packeable writing (unsafe but faster)

class PackeablePixel a where #

This typeclass exist for performance reason, it allow to pack a pixel value to a simpler "primitive" data type to allow faster writing to moemory.

Associated Types

type PackedRepresentation a #

Primitive type asociated to the current pixel It's Word32 for PixelRGBA8 for instance

Methods

packPixel :: a -> PackedRepresentation a #

The packing function, allowing to transform to a primitive.

unpackPixel :: PackedRepresentation a -> a #

Inverse transformation, to speed up reading
