Subject: Re: Transparent Layer to draw
In reply to: Holger 's message, "Transparent Layer to draw" on 04:19:03 03/25/02 Mon


Hi Holger,

There is no easy solution for this. I am currently working on something similar for annotations. You need to create a TCanvas on the drawing surface, and keep those "data structures" , ie layers, independent of the graphic. This is a what the TRubberbandMouseHandler does; in draws on a display canvas, not on the image itself.

Best regards,

Michel
