Just a question, not a request and sorry if this is not related to this mailling list:
Just wanna know if this card will support Video Blitter.(ie. put some cropped images of original ones with aritrary scaling ratio to any position of the screen. If you use nvidia graphics card, type 'xvinfo' in an Xwindow terminal and you will know what I mean. However, this feature of nvidia only functions on traditional video ram and that makes somehow inconvinient). If this card can support Video Overlay with video blitter function in the off-screen, then it can really overlay off-screen images to real screen. And we can make good use of the colorkey. So far there is no graphics card support this kind of function. It is useful when developing digital security monitoring known as DVR. With several scaled videos on the screen, each video has its own osd and each video has its own scaled ratio. This cannot be happened if you use today's Video Overlay function without extra memory copy and even without software scaling. As in realtime monitoring, today's graphics cards are insufficient. Thanks for reading my stupid question. _______________________________________________ Open-graphics mailing list [email protected] http://lists.duskglow.com/mailman/listinfo/open-graphics List service provided by Duskglow Consulting, LLC (www.duskglow.com)
