## Overview

Resynthesizer is a GIMP plugin suite backed by a reusable C texture-synthesis engine. The principal result is synthesized or transformed image content: GIMP-facing code adapts drawable data and parameters for the engine, which performs synthesis. An expert control panel separately invokes the engine plugin through GIMP’s procedure database (PDB). The README names a broader plugin suite, but sampled plugin excerpts do not establish their individual runtime calls; those links are therefore omitted. The graph shows documented capabilities and only evidenced control-flow relationships.

Main entry points: [`lib/engine.c`](https://github.com/bootchk/resynthesizer/blob/master/lib/engine.c) (Synthesis engine), [`src/resynthesizer/resynthesizer.c`](https://github.com/bootchk/resynthesizer/blob/master/src/resynthesizer/resynthesizer.c) (Engine plugin), [`src/resynthesizer-gui/resynth-gui.c`](https://github.com/bootchk/resynthesizer/blob/master/src/resynthesizer-gui/resynth-gui.c) (Control panel), [`src/resynth-parameters.h`](https://github.com/bootchk/resynthesizer/blob/master/src/resynth-parameters.h) (Plugin parameters)
