This is designed to post-process the SVG output from the brilliant free Paint by Number Generator at paint-by-number.com
Given the SVG file, it separates the different kinds of shapes (number labels, region outlines, and colours for regions) into different layers
It also produces an output that doesn't contain the region colours, so is more suitable for printing.
It outputs in SVG and PNG, with the names having a suffix of Layers
or Outlines
accordingly.
