raster2svg

A tool that use the contour_tracing library

Features

Support RGB colors + alpha channel (fully transparent colors are not traced)
Sort the colors from the most used to the less used
Input format: a raster image file
Output format: an SVG file

Features from the contour_tracing library: - Trace contours using the Theo Pavlidis' algorithm (connectivity: 4-connected) - Trace outlines in clockwise direction - Trace holes in counterclockwise direction

Options

``` -s, --size Add the width, height and viewBox attributes -d, --ids Add the RGB colors and opacity values as id attributes -k, --inkscape Add some Inkscape attributes (transparent background, pixel units, grid, snapping, ...) -r, --rendering Set the shape-rendering attribute at crispEdges -c, --closepaths Close the paths with the SVG Path Z command

-z, --zoom Multiply the width and height attributes by a given percent (e.g. 250) -i, --input Input raster image filename (e.g. input.png) -o, --output Output SVG filename (e.g. output.svg) ```

An example with some transparent colors

C:\>raster2svg.exe -s -d -k -r -i rust_input.png -o rust_output.svg - rustinput.png:

Informations

Be careful with the size and complexity of your input image because the SVG file size grows rapidly...
