Does anyone in here know if there is a way to let new POLYGON function
(or similar) in IDL8 produce polygons overlays filled with texture
patterns. Or more precisely, filled with warped images like the old
POLYFILL procedure.
I have started to transfer my GUI routines from direct graphics to the
new Graphics system, and suddenly my whole application lost that
authentic 1994 look and feel. And I guess, by the time I finish, the
user friendlyness should have increased by an order of magnitude. :)
Please tell me that I do not have to teach my self the "old" object
graphics stuff, and write everything from scratch.
Best Regards,
Stian Solbø

The solution to this problem is found, thanks to Jim Pendelton and his
insight into object graphics and UNDOCUMENTED features of the new
graphics system.
The following example will produce a texture filled polygon:
p = plot([0, 1], [0, 1])
poly = polygon([0.1, 0.9, 0.8, 0], [0.2, 0.1, 0.9, 0.7], color = [255,
255, 255], style =2, /data)
poly.texture_coord =[[0,0],[1,0],[1,1],[0,1],[0,0]]
poly.texture_map = IDLgrImage(bytscl(dist(256)))
I hope this information can be helpful to others.
