Hi, I want to transfer a block of image data from source offset in off_screen to a specified rectangular area in on_screen area. If the source image is saved with rectangular trajectory, I can set some registers such as SRC_Y_X, DR_MIX, DP_CNTL,DST_Y_X and DST_HEIGHT_WIDTH to transfer pixels from SRC_Y_X to DST_Y_X. However, in order to save memory space, I want to save the image data in frame buffer with lineal trajectory instead of a rectangular area. Can I still transfer the image pixels by just setting some registers?
If I can, which register is for src offset? If cannot, a possible value of register DP_SRC_SOURCE is "hostdata,lineal trajectory", and I guess it means that I can set some register value to source address, in which image data is saved in continuous address in host memory. But what is this register? I had a tough time to find it. :( Thank you so~~~ much, jing _______________________________________________ Devel mailing list [EMAIL PROTECTED] http://XFree86.Org/mailman/listinfo/devel
