[PD] using graphics tablet for input

[Thomas Grill]

Hi all,
has anyone worked out a general scheme to use a graphics tablet for
triggering events in the sense that one has a map sticked to its surface
where several zones can be defined and recognized in a PD patch?

I was thinking of a very general system which includes drawing the map,
printing it and stuffing the (metafile graphics format of the) map into an
object to get out the zones triggered by the tablet coordinates. This
procedure shouldn't be too time-consuming to quickly sketch new setups.
Which portable graphics format could be used for that? The only usable one
that i know is DXF but that doesn't seem to be common apart from the CAD
world....

greetings,
Thomas
