serves SVG files, hit-test on click, extracts the pattern, feeds tttool
requires the Inkscape-based workflow as outlined below
Workflow
Use Inkscape to create your TipToi Sheets as SVG
(opposed to the GIMP-based raster image approach).
You may load a raster image in a background layer.
For the OIDs, draw a path and fill it with a pattern created by tttool.
use tttool as usual to work on your GME file.
export the oid table as SVG (use --image-format SVG for the oid-table command).
use the inject-patterns.py to inject the patterns from the oid-table SVG into your target SVG.
(this can be done over and over again, which allows to work on the YAML and SVG in parallel.)
use ttsim.py to fire up a local web server to try out your TipToi Sheet in a browser
(there you can click onto the image instead of hacking numbers into tttool play).
