I have one image on a RGB24 (DSPF_RGB24) surface and a separate alpha mask in an 8-bit alpha surface (DSPF_A8). I am trying to blit the image onto a second RGB24 surface using the 8 bit alpha as the mask for the blit, in other words I want the source pixels to replace destination pixels where alpha = 0xff, otherwise the destination pixels should stay the same. Note that the alpha is stored separately in an 8 bit surface for historical / code porting reasons, but the only possible value for each alpha pixel in this case will be either 0 or 0xff.
What is the best / most efficient way to do this with the DirectFB api, given the constraints above? - Mark _______________________________________________ directfb-users mailing list directfb-users@directfb.org http://mail.directfb.org/cgi-bin/mailman/listinfo/directfb-users
