There's no other way. I didn't want to have two functions for that when I added the location setting. But thinking about that again would anyone mind an additional 'SetPixelLocation' function? > 2) How can I switch Bes layer on and off - means to be visible and not > (I want to keep the layer while is off) You can the layer opacity to '0'.

It's not possible to put the BES under the primary layer. However the BES supports color keying based on pixels within the primary layer, like destination color keying. DirectFB supports color keying for layers using the 'source color keying' like version. The destination based color keying has to be added to the API. > 5) This more theoretic - could be possible to set second framebuffer as > source for BES (eg.

You can choose the device with the "--fbdev=<device>" option. Using several devices simultaneously by one DirectFB session requires many internal changes that are already planned. Once done it should be possible to use the card like one with two outputs by utilizing both framebuffer devices. We are still thinking about the external API for multi head support. -- 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-users" as subject.
