Sharpen Deluxe a new Gimp Plugin to sharpen images (by generating a high pass mask)

*download here https://github.com/LinuxBeaver/Gimp_Sharpen_Plugin/releases

This is a Gimp GEGL plugin, it expects the user to use Gimp's built in Blending Options, also known as blend modes. All GEGL filters in Gimp have "blending options" with a long list of all Gimps blend modes. If you don't use that then it will just create a "high pass layer". which is a grayscale-ish layer can be stacked above and manually blended using Gimp's layers.

After you install, restart Gimp and go to GEGL operations and look for "Sharpen Deluxe". If you are using Gimp 2.99.16 you will see this filter under Filters>Enhance.

To explain this filter a bit more technically. The following filters listed.

Median Blur

DCT Denoise

Box Blur

Mean Curvature Blur

Domain Transform Smooth

Noise Reduction

Lens Blur

Gaussian Blur

are all individually being grain extracted to create a high pass. Gimp's grain extract blend mode gives you the high pass layer and you do what you want with the high pass layer from there.

Compiling and Installing

Linux

To compile and install you will need the GEGL header files (libgegl-dev on Debian based distributions or gegl on Arch Linux) and meson (meson on most distributions).

meson setup --buildtype=release build
ninja -C build

Windows

The easiest way to compile this project on Windows is by using msys2. Download and install it from here: https://www.msys2.org/

Open a msys2 terminal with C:\msys64\mingw64.exe. Run the following to install required build dependencies:

pacman --noconfirm -S base-devel mingw-w64-x86_64-toolchain mingw-w64-x86_64-meson mingw-w64-x86_64-gegl

Then build the same way you would on Linux:

meson setup --buildtype=release build
ninja -C build
