# Post Process a bitmap image traced with Inkscape's Trace Bitmap tool
|
|
# The output of Trace Bitmap is traversed and each <path> is put into
|
|
# an Inkscape layer whose name is Eggbot friendly. Owing to how the
|
|
# Trace Bitmap tool operates in Inkscape 0.48, all the traced regions
|
|
# of a given "scanned" color are put into a single <path>. This makes
|
|
# it easy to put all the traced regions of a single color into a single
|
|
# layer: just put each <path> into its own layer.
