You can set the background color alpha to transparent for your display layer using
IDirectFBDisplayLayer-> SetBackgroundColor<http://www.directfb.org/docs/DirectFB_Reference_1_4/IDirectFBDisplayLayer_SetBackgroundColor.html>(r, g, b, a) From: directfb-users-boun...@directfb.org [mailto:directfb-users-boun...@directfb.org] On Behalf Of Wejdene SMIDA Sent: Friday, October 08, 2010 6:48 AM To: directfb-users@directfb.org Subject: [directfb-users] changing background opacity Hi everybody, I'm too new with directFB, I'm using the 1.4.3 version cross-compiled for the STB5202 platform. This is the scenario: I'm displaying a video using ST application on the first layer, and my purpose it to show a small browser window over the video so that we can see both of the video and the browser. The problem I'm facing is the transparency: when the global alpha value is set to be full opaque, the video can not be displayed anymore (it's hidden), and when I decrease the alpha value I can see both the video and the browser but the browser window is not opaque (it takes naturally in consideration the global alpha value) My question: Is there any way to change the background opacity so that it can be transparent (in order to display the video)? Thanks in advance, -- Wejden
