Hi Niels, I am a beginner to DFB. Could you let me how to set the alpha value of a specified pixel on a surface? For example, can I set the alpha to 50% transparent of all the pixel in the top half of a image surface?
I tried SetSourceMask to get a semi-transparent image by using an alpha png file on a normal jpg image. But it did not work. My previous post described my problem. I read the DirectFB demo df_dok. But still cannot figure it out. Thank you very much for any help! -Jack --- On Thu, 11/12/09, Niels Roest <[email protected]> wrote: From: Niels Roest <[email protected]> Subject: Re: [directfb-dev] Applying different alpha values for different regions in the same window To: "Rajesh k" <[email protected]> Cc: [email protected] Date: Thursday, November 12, 2009, 7:13 AM You cannot. Either make multiple windows, or use a per-pixel-alpha-value.
