In order to be able to view images in GHCi an external image viewer is used. You
can use any viewer that accepts a filename as an argument, and by default, image
viewer specified by the OS is used.
Changes
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.
