How do I implement very fast image producing?
From: "Soohyung Cho" ####@####.#### Date: 4 Jan 2001 03:05:06 -0000 Message-Id: <NMEMKMPHBABAPAABEBDECEAJCAAA.xfree@mail.hitel.net> Hi, I work on iPaq with microwindows. My application needs very fast image producing on display screen. Currently, I send my image by calling GrArea function. I want more fast method. Is it possible to draw image directly on display screen buffer? Please help me. bye. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

If it is possible for you to maintain a double buffer, then you should use a offscreen pixmap and just GrCopyArea the pixmap to the main window when you need to display (kind of like how nxBill works). However, if you are just trying to display a series of images (like Doom, for example), then right now GrArea is your best bet. Greg Haerr is currently working on implementing client side screen buffers, so stay tuned. Happy hacking!

My next big project is to write blitting routines for copy, color-key, and alpha-blending for each bpp screen driver, as well as conversion routines between bpps. Currently, Microwindows has a special-cased 16bpp driver for GrArea, you might look into that. You can draw directly to the display buffer currently only if you link your application to the server, thus getting memory-mapped access. I hope to add client-side memory-mapping as well in the next major cut. Regards, Greg | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
