the hardware limitation that I know of is the graphics card memory (that limits the max size any textures can be) - the way I've got around that in a more general way is splitting long images into separate 4x3 files and using an abstraction with two gemheads, alternating between the smaller files - I could also post that if you wanted. simon _______________________________________________ PD-list@iem.at mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list
