Tools/Directories.py: Get rid of "fallback" in resolveFilename
[openblackhole/openblackhole-enigma2.git] / tools / svg2skin.py
1 #!/usr/bin/python
2 # don't expect too much.
3 # this is a really simple&stupid svg parser, which will use rectangles
4 # and text fields to produce <widget> snippets for a skin.
5 # use object "id" fields for source names if you want.
6 # extracting font information is buggy.
7 # if you want text fields, please use flow text regions, instead of simple
8 # text. otherwise, width and height are unknown.
9 #
10 # tested only with a single inkscape-generated SVG.
