http://msdn.microsoft.com/en-us/library/ee719797(v=vs.85).aspx Efficient pixel formats are 32 bits wide. rgb is for directx http://msdn.microsoft.com/en-us/library/aa753543(v=vs.85).aspx I am not sure what bgr is for. I have a vague memory of it being used in .bmp files, but when I looke them up, wikipedia says they are rgb (wikipedia is inaccurate often enough but I still would hope that for something this narrow and specific someone would have noticed and fixed it if it was wrong) -- Raul ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
