* Updating the repo to use Directory.Build.props/targets files
* Adding an InternalsVisibleTo for DynamicProxyGenAssembly2, PublicKeyToken=null
* Removing duplicate includes from the ImageSharp.csproj
* Updating the .gitattributes file to explicitly list the line endings
* Removing the ImageSharp.ruleset file, as the one from standards should be used instead
* Updating the package version management to use `PackageReference Update`
* temporarily disable target frameworks
* drop DelegateProcessor
* drop IImageProcessingContext<TPixel>
* drop NamedColors<T>
* drop ColorBuilder<T>
* drop the *Base postfix for clean class hierarchies
* re-enable target frameworks
* use MathF in gradient brushes
* Move PngFilterMethod to the correct namespace.
* first version of sliding window adaptive histogram equalization
* going now from top to bottom of the image, added more comments
* using memory allocator to create the histogram and the cdf
* mirroring rows which exceeds the borders
* mirroring also left and right borders
* gridsize and cliplimit are now parameters of the constructor
* using Parallel.For
* only applying clipping once, effect applying it multiple times is neglectable
* added abstract base class for histogram equalization, added option to enable / disable clipping
* small improvements
* clipLimit now in percent of the total number of pixels in the grid
* optimization: only calculating the cdf until the maximum histogram index
* fix: using configuration from the parameter instead of the default
* removed unnecessary loops in CalculateCdf, fixed typo in method name AddPixelsToHistogram
* added different approach for ahe: image is split up in tiles, cdf is computed for each tile. Grey value will be determined by interpolating between 4 tiles
* simplified interpolation between the tiles
* number of tiles is now fixed and depended on the width and height of the image
* moved calculating LUT's into separate method
* number of tiles is now part of the options and will be used with the sliding window approach also, so both methods are comparable
* removed no longer valid xml comment
* attempt fixing the borders
* refactoring to improve readability
* linear interpolation in the border tiles
* refactored processing the borders into separate methods
* fixing corner tiles
* fixed build errors
* fixing mistake during merge from upstream: setting test images to "update Resize reference output because of improved ResizeKernelMap calculations"
* using Parallel.ForEach for all inner tile calculations
* using Parallel.ForEach to calculate the lookup tables
* re-using pre allocated pixel row in GetPixelRow
* fixed issue with the border tiles, when tile width != tile height
* changed default value for ClipHistogram to false again
* alpha channel from the original image is now preserved
* added unit tests for adaptive histogram equalization
* Update External
* 2x faster adaptive tiled processor
* Remove double indexing and bounds checks
* Begin optimizing the global histogram
* Parallelize GlobalHistogramEqualizationProcessor
* Moving sliding window from left to right instead of from top to bottom
* The tile width and height is again depended on the image width: image.Width / Tiles
* Removed keeping track of the maximum histogram position
* Updated reference image for sliding window AHE for moving the sliding window from left to right
* Removed unnecessary call to Span.Clear(), all values are overwritten anyway
* Revert "Moving sliding window from left to right instead of from top to bottom"
This reverts commit 8f19e5edd2.
# Conflicts:
# src/ImageSharp/Processing/Processors/Normalization/AdaptiveHistEqualizationSWProcessor.cs
* Split GetPixelRow in two version: one which mirrors the edges (only needed in the borders of the images) and one which does not
* Refactoring and cleanup sliding window processor
* Added an upper limit of 100 tiles
* Performance tweaks
* Update External
* Read from underlying stream less often
* Update benchmark dependencies
* Experimental mango port
Currently broken
* Populate table, 64byte buffer
Still broken.
* Baseline, non RST works
* 15/19 baseline tests pass now.
* Optimize position change.
* 18/19 pass
* 19/19 baseline decoded
* Can now decode all images.
* Now faster and much cleaner.
* Cleanup
* Fix reader, update benchmarks
* Update dependencies
* Remove unused method
* No need to clean initial buffer
* Remove bounds check on ReadByte()
* Refactor from feedback
* Remove multiple premultiplication.
* Use in DenseMatrix everywhere.
* Make private
* Dont convert vector row on first pass
* Remove incorrectly assigned alpha.
* Remove boxing.
* Use correct min row.
* Reorder parameters
* Correctly handle alpha component.
* Update tests
* Use dedicated methods over branching.
