Wichura) Newsgroups: comp.sys.amiga.programmer Subject: help with struct Image Message-ID: Date: 21 Apr 91 04:52:44 GMT Lines: 17 I'm working on a project in which I have a struct Image of depth one. I've got a need to render it in normal video and reverse video. Is there an easy way to draw an XOR of the image without 1) modifying the original image, 2) boating a second, XORed, copy of the image around in my code or 3) having to allocate a temporary buffer into which to XOR it? I'm thinking I could just DrawImage() it and then use one of the graphics library blitter functions to do the XOR for me. However, I'm no blitter champ. Hell, I've hardly done anything with graphics.library before so this is new ground for me here. Thanks, -=> CAW Christopher A. Wichura Multitasking. Just DO it. caw@miroc.chi.il.us (my amiga) ...the Amiga way... u12401@uicvm.uic.edu (school account)
