Module documentation for 1.3.0.0

Haskell Image Processing Library

Haskell Image Processing (HIP) Library

Documentation is on Hackage, and Stackage.

Build Status Hackage

Installation

Install HIP using cabal:

  • $ cabal update && cabal install hip

and using stack:

  • $ stack install hip

In order to be able to view images in GHCi and external image viewer is used. On Linux I recommend GPicView, but you can use any viewer that accepts a filename as an argument, so by default OS specific image viewer is used.

Changes

1.3.0.0

  • Significantly simplified interface:
    • Removed ManifestArray, SequentialArray and MutableArray classes in favor of MArray.
  • Rewrite of Repa image representations. Removed RD representation.
  • Introduced function canvasSize.

1.2.0.0

  • Changed Interpolation in a way that border resolution is supplied separatly from the method.
  • Introduced function translate.
  • Added a better test suite. Improved coverage.
  • Fixed a bug with border resolution strategy Continue.
  • Added better error messaging for border checks.

1.1.0.0

  • GHC 8 support.
  • Improved IO:
    • OS default image viewer is used for displaying images with ability to use a custom one.
    • Histogram plotting is done using diagrams instead of cairo backend, significantly simplifying installation

1.0.2.0

  • Changed the way image displaying works. Now displayImage function will try to automatically detect the default external viewer program.
  • Renamed module Graphics.Image.IO.External to Graphics.Image.IO.Formats, so it reflects the purpose slightly better.
