This module defines two Hakyll compilers. The first one, resizeImageCompiler
,
is used to resize images to specific dimensions. The aspect ratio might not be the same.
The other compiler, scaleImageCompiler
, scales images to fit within a specified
box while preserving aspect ratio.
import Hakyll import Hakyll.Images ( loadImage , resizeImageCompiler , scaleImageCompiler ) hakyll $ do -- Resize all profile pictures with .png extensions to 64x48 match "profiles/**.png" $ do route idRoute compile $ loadImage >>= resizeImageCompiler 64 48 -- Scale images to fit within a 600x400 box match "images/**" $ do route idRoute compile $ loadImage >>= scaleImageCompiler 600 400 (... omitted ...)

Documentation
resize :: Width -> Height -> DynamicImage -> DynamicImage Source #
Resize an image to specified width and height using the bilinear transform. The aspect ratio may not be respected.
In the process, an image is converted to RGBA8. Therefore, some information loss may occur.
resizeImageCompiler :: Width -> Height -> Item Image -> Compiler (Item Image) Source #
Compiler that resizes images to a specific dimensions. Aspect ratio may not be preserved.
match "*.png" $ do route idRoute compile $ loadImage >>= resizeImageCompiler 48 64
scale :: Width -> Height -> DynamicImage -> DynamicImage Source #
Scale an image to a size that will fit in the specified width and height, while preserving aspect ratio.
In the process, an image is converted to RGBA8. Therefore, some information loss may occur.
