Another problem is the memory allocation. If you have five layers, each of them can be configured up to 1280x768 at 16 bit you have to allocate at least 1966080 (~2M) for each of them. You divide your total amount of available memory into five static partitions instead of managing one big chunk much more intelligently, with allocations only if the layer is really used, giving room for offscreen images etc. -- Best regards, Denis Oliver Kropp .------------------------------------------. | DirectFB - Hardware accelerated graphics | | http://www.directfb.org/ | "------------------------------------------" _______________________________________________ directfb-dev mailing list [email protected] http://mail.directfb.org/cgi-bin/mailman/listinfo/directfb-dev
