hakyll-images

A Haskell package containing utilities to deal with images in the context of Hakyll

Hakyll is a static website compiler library. As one of the benefits of static websites is their small size, this repository aims at providing utilities to work with images in the context of Hakyll. Example usage includes:

Re-encoding Jpeg images at a lower quality to make them much smaller;
Re-sizing images to fit within a certain shape;

Usage

hakyll-images is meant to be integrated within a Hakyll program. Here are some examples within a Hakyll program:

import Hakyll
import Hakyll.Images        ( loadImage
                            , compressJpgCompiler
                            , resizeImageCompiler
                            , scaleImageCompiler
                            )

(...)

hakyll $ do

    -- Compress all source Jpegs to a Jpeg quality of 50 (maximum of 100)
    match "images/**.jpg" $ do
        route idRoute
        compile $ loadImage 
            >>= compressJpgCompiler 50

    -- Resize all profile pictures to 64x48
    -- Aspect ratio might be mangled
    match "profiles/**.jpg" $ do
        route idRoute
        compile $ loadImage 
            >>= resizeImageCompiler 64 48
            >>= compressJpgCompiler 50

    -- Scale images to fit within a 600x400 box
    -- Aspect ratio will be preserved
    match "images/**.png" $ do
        route idRoute
        compile $ loadImage
            >>= scaleImageCompiler 600 400

    (...)

Take a look at the documentation for more usage examples.
