1.5.6.0

• Addition of Bicubic interpolation (Thanks to @kirisaki)

1.5.5.0

• Ability to encode animated gifs

1.5.4.0

• Addition of disable-chart flag
• Bunch of semi-functional stuff from GSoC 2018

1.5.3.0

• Fixed FFT performace issue
• Reduced JuicyPixels module compile time and introduced conversion functions.
• Created Filter and implemented few filters: gaussianBlur
• Indroduced Seq format wrapper for sequence of images (eg. animated GIFs)

1.5.2.0

• Fixed Storable instance for some Pixel types.
• Fixed reading/writing animated GIFs. Added a detailed example to documentation.
• Improved encoding/decoding of images.
• Improved coversion between ColorSpaces.

1.5.1.0

• Significantly improved convolution performance.
• Improved exchanging representation between images, by removing Exchangable class, but keeping exchange function usage unchaged, thus it should be backwards compatible up to a type signature.
• Created general fromVector to toVector functions
• Brought back fromRepaArrayS and fromRepaArrayP functions [#6]

1.5.0.0

• Refactored Gray color space to be X, in order to reflect it's generality

• Renamed few core functions:

  • mapPx -> liftPx,
  • zipWithPx -> liftPx2,
  • broadcastC -> promote,
  • singleton -> scalar.

• upsample/downsample functions are now a lot more general.

1.4.0.1

• Fixed the ability to construct complex images by installing Complex into Elevator
• Made it possible to write complex images by concatenating real and imaginary part together.
• Fixed writing images in other representation than VS.

1.4.0.0

Major rewrite, with most of functionality is still backwards compatible, but with a some extra features.

• Storable Repa and Vector representations through generic implementations
• ColorSpace is more general allowing for non polymorphic Pixel types
• Elevator works on base types rather than on pixels
• Conversions from JuicyPixels and NetPbm is done through casting a Vector rather than through an explicit conversion.

Major API changes:

• Renaming RS and RP Repa representations into RSU and RPU.
• Addition VS Storable Vector representationas well as RSS and RPS Storable Repa representations.

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.

1.1.0.1

• Backwards compatibility with GHC 7.8

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.

1.0.1.2

• Added support of "vector>=0.11.0.0"

1.0.1.1

• Added rotate function.
• Fixed writing RGBA files with writeImage (#2).

1.0.1

• Made it compatible with GHC >= 7.4 (#1)
• Added histogram plotting using Charts
