A friendly fork of StippleGen_2 from Evil Mad Scientist Laboratories.
This script takes an image, provided as a JPEG, a PNG or a TIFF (generated by Processing) and outputs both an SVG for a plotter as well as a approximation as a JPEG, PNG or TIFF.
There have also been features added to do the following:
- Custom output SVG scale
- Custom canvas size
- Option to fill in circles with hatch lines
stipple_gen is designed to be configured and run from the command line, rather than the GUI provided in the original sketch.
By creating a config.txt file in your sketch directory OR providing command line arguments to your sketch you can set all of the variables accessible to the GUI in the original StippleGen_2 sketch and then some.
An example using the helpful
stipple_gen.sh script provided by this project.
bash stipple_gen.sh --display true --inputImage myImage.jpg --outputImage myStippledImage.jpg --outputSVG myStippledDrawing.svg
This will take your original image
myImage.jpg and run it through the stippling process using the default variables for everything and output two files for you:
myStippledDrawing.svg, the latter of which you can use on your plotter.
--display true arguments will show the progress of the script in the main window, which the default. Run it headless with
public int canvasWidth = 800; public int canvasHeight = 600; public float canvasScalar = 1.0; public boolean display = true; public int windowWidth = 800; public int windowHeight = 600; public boolean invert = false; public boolean selectInput = false; public String inputImage; public String outputImage; public String outputSVG; public int centroidsPerPass = 500; public int testsPerFrame = 90000; public int maxGenerations = 5; //number of generations public float minDotSize = 1.25; public float maxDotSize; public float dotSizeFactor = 4; public int maxParticles = 2000; // Max value is normally 10000. public float cutoff = 0; // White cutoff value public boolean gammaCorrection = false; public float gamma = 1.0; public boolean fill = false; public boolean dot = false; public float line = 1.0;
This sketch can also be run from the Processing IDE, though it is best to provide arguments with a local
config.txt file when doing so.
There isn't a consistent way to provide command line arguments to the IDE on all platforms.
