[FilterScript] Preserve EXIF data
Blend image with itself
When both arguments point to the same Bitmap object in PerPixelBlendBase, an exception is thrown (System.InvalidOperationException : Bitmap region is already locked.) because we try to lock the same Bitmap twice. An easy fix would be to detect this and do a clone.
Normalization for grayscale filter parameters
Color for vignette filter
Vignette filter is currently just black, but an arbitrary color could easily be given
Port other filters
- ConvertToPolarFilter.cs
- ConvolutionFilter.cs
- EquirectangularToStereographicFilter.cs
-
RedEyeRemovalFilter.cs -
TvScanLinesFilter.cs - WavesFilter.cs
Use MathF instead of Math and float casts
[FilterScript] Proper parsing of command line arguments
Validation, -- flags, ...
Radius for median filter

Port mosaic filters
- CrystallizeFilter.cs
- LegoFilter.cs
- PixelerateFilter.cs
Custom logic for lego filter
... that doesn't use Graphics.
Tests for blend modes
Currently there are no separate unit tests for blend modes, they are only indirectly tested through filters that use them.
[FilterScript] Dispose intermediate results in batch
[FilterScript] Add integration tests
Port dither filters
- BayerDitherFilter.cs
- FloydSteinbergDitherFilter.cs
- JarvisJudiceNinkeDitherFilter.cs
- RandomDitherColorFilter.cs
- RandomDitherGrayscaleFilter.cs

Implement Burkes dither
. . * 4 2
1 2 4 2 1
Implement Shiau-Fan dither
. . * 4
1 1 2 .
Box downscaling
Create a downscale-only resize that averages pixels to get the new one.
Custom crop filter
... that does not rely on Graphics
Add tests for dither using grayscale input

- PosterizeFilter.cs
- SepiaFilter.cs
- TresholdFilter.cs
- VintageFilter.cs
Common base class for Prewitt and Sobel filters
Port sharpen filters
- MeanRemovalFilter.cs
- SharpenFilter.cs
Do not ignore image edges in convolution filter
Edges of the image (top,right,bottom,left 1px) are currently ignored. Would be better to e.g. duplicate pixels.
[FilterScript] Generate documentation
It would be nice to automatically generate some documentation with the available filters, their parameters and some examples.
[FilterScript] Support batch execution on folder
Relative/absolute parameter
Filters (such as resize, border, crop, ...) would need a type, which can express parameters both relative (%) and absolute (px).
Add test for blending images with different size
