IDLgrView question [message #83793]

Hi gang,

I've been developing this GUI to display/process images and I'm using the object-oriented graphics. Everything is going great, but I'd like to set the background of the View to be a repeating image or pattern. I know I can set it to a flat color (I'm using [192,192,192] so it blends in with the standard IDL GUI background), but I'd like to do something like a series of diagonal lines (so it's more obvious where the image boundary is). I'm imagining something like polyfill with /line_fill set, but obviously it must be integrated into the OOGs. I know about the IDLgrPattern object which I could set to an IDLgrPolygon, but then every time I pan/zoom the image I'd have to reset the position/size of the polygon. That seems pretty tedious, and I was hoping there was a better way...

Any ideas on how to do this?

Thanks!
Russell
