Please see http://micha.elmueller.net/2014/04/scratches/ for a description of this project.
In chronological order:
- Cropping original Matlab PNGs, so that no border around the image is left (using Gimp Autocrop or manullay adjusting the canvas size in cases where that didn't work).
- Using Inkscape as a mean to transform the PNG into SVG (via "Path > Trace Bitmap", using the "Colors" mode, 100 scans, no smoothing, stack scans enabled and no background removal).
- Scaling those SVGs into a common format (DIN A3 proportions). See the
resizesvgscommand in the
And then optionally:
- Transforming those SVGs back into a PNG. See the command
renderpngsin the Makefile.
