Hi, sorry for the late answer. Currently there's no display rotation support in DirectFB as it requires some important changes. The main problem is to keep everything accelerated. I haven't seen a chip yet supporting realtime rotation, so it would be necessary to rotate the data ourselves. At least with a texture mapping unit we could accelerate it ;) Maybe there are some normal blitters supporting it. Blitters that have direction settings for both the source and the destination should be useful. We are planning support for rotation during flips. So it should work in windowed mode and full screen double buffered. -- Best regards, Denis Oliver Kropp .------------------------------------------. | DirectFB - Hardware accelerated graphics | | http://www.directfb.org/ | "------------------------------------------" convergence integrated media GmbH -- Info: To unsubscribe send a mail to [EMAIL PROTECTED] with "unsubscribe directfb-dev" as subject.
