ofxPlotProcessors

Composable stroke pipeline for pen plotters: merge, sort, filter, transform, layout, and clip on ofPath strokes before G-code export.

Works with ofxPlotFinders (image → strokes) and ofxPlotter (ECS, UI, export).

Quick start

#include "ofxPlotProcessors.h"

plotproc::StrokeDocument doc = / from layer or finders /;
plotproc::PlotPipeline pipe = plotproc::PlotPipeline::loadPreset("bin/data/plot_pipeline_default.json");
pipe.run(doc);

Default pipeline

bin/data/plot_pipeline_default.json — line_merge → line_sort (squiggles/filter optional).

Credits

Many processors in this addon follow ideas from vpype by Antoine Beyeler (MIT)—a brilliant toolchain for pen-plot workflows. Thank you, Antoine.

ofxPlotProcessors is a native openFrameworks library for in-app pipelines; it is not a port of vpype.
