bsz-gimp-plugins

Plugins for GIMP 2.99.18+

Installation

Either

• Download the release and unpack it into your already existing plugins folder
• Or, for cleanliness, unpack the release to its own folder and add that folder as a plug-in directory in Gimp's folder settings

Building

Needs the bszgw.py file from https://github.com/Beinsezii/BSZGW at the root. Will be bundled with releases.

Compiling any shared libraries needs rustc and the rustup toolchain for the target platform. Small build scripts provided for Linux.

Current Plugins

Dual Bloom

Provides light and dark bloom using thresholds. Based on my own custom bloom methods.

Before	After

Dual Bloom 2

Produces both a light and dark bloom, based on gimp/gegl's existing bloom.

Before	After

Filmic Chroma

Reduces/increases chroma based on intensity. Inspired by Blender's new 'Filmic' tonemapper.

Before	After

Lightgrain

LCH Noise masked to Lightness

Before	After

Pixel Math

Enter custom Python algorithms for pixel math.

Pixelbuster

Enter basic operations to perform pixel math. More limited, but processes well over 20x faster than Pixel Math in the worst scenarios.

bsz_gimp_lib

Shared library for plugins. Notably contains a complete plugin auto-builder. Similar to the old python-fu, but (imo) significantly more customizable at a mild complexity cost. Features include

• Semi-live previews using gegl buffers.
• UI that isn't just a bunch of widgets smashed into a column (but it can be if that's what you want)
  • Chains
  • Logarithmic scales courtesy of BSZGW
• Extensible using the Param abstract class. Plugins can make their own widgets/parameters.
  • Has built-in Param derivatives for most common data input fields.
• Somewhat documented mostly in nice words. Check out bsz-dualbloom.py for a decent GEGL filter example, and bsz-filmic-chroma.py for a decent custom math/FFI example. This obviously can't cover every plugin use scenario, but I'd say covering 95% of use cases is good enough.

Other non-plugin-builder bits include:

• Premade dictionary of Gegl compositors
  • Ripped from the gegl site's html.
  • Only includes operations that use pads input, aux, output.
• PDB quick function. WIP, many datatypes not supported.
