Straight line control point radius, if this is greater than zero, small circles will be drawn in the SVG. 1f is on, 0f is off.Įnable or disable SVG descriptions. 1f means rounded to 1 decimal place like 7.3 3f means rounded to 3 places, like 7.356Įnable or disable SVG viewBox. Rounding coordinates to a given decimal place. RGBA delta treshold for selective Gaussian blur preprocessing.Įvery coordinate will be multiplied with this, to scale the SVG. Set this to 1f.5f for selective Gaussian blur preprocessing. Number of colors to use on palette if pal object is not defined.Ĭolor quantization will randomize a color if fewer pixels than (total pixels*mincolorratio) has it.Ĭolor quantization will be repeated this many times.

There are more functions for advanced users, read the source if you are interested.

Options HashMap options = new HashMap() Warning: if the outfilename parameter is not specified, then this will overwrite. background field is removed from the results of color quantization.colorquantization() needs now only imgd, palette and options as parameters.getsvgstring() needs now only IndexedImage (tracedata) and options as parameters.

This can filter noise and improve quality.

new options.blurradius : setting this to 1.5 will preprocess the image with a selective Gaussian blur with options.blurdelta treshold.

new lorsampling : color quantization will sample the colors now by default, can be turned off.

new options.viewbox : setting this to true will use viewBox instead of exact width and height.

new sc : setting this to false will turn off path descriptions, reducing SVG length.

This can reduce SVG length significantly (>20%) with minor loss of precision.

new options.roundcoords : rounding coordinates to a given decimal place.

transparency support: alpha is not discarded now, it is given more weight in color quantization.

Bugfix: CSS3 RGBA output in SVG was technically incorrect (however supported by major browsers), so this is changed.

This is a port of imagetracer.js: Check this out for a refactored version with better color quantization algorithm: Check this out for a C++ port: 1.1.2 Simple raster image tracer and vectorizer written in Java for desktop.
