Title: Samsung Enterprise Portal mySingle
Hi Jack,
Even i was looking for the same sometime ago and could not find any direct
API to do this. If some body knows, pls. help. I managed to achieve it by some
workaround.
Get the pixel data for every pixel surface by using surface's Lock API and
modify the alpha content as required ( eg. for 32 bit, color format ARGB, modify
the 4th byte as required ).
Hope it helps.
Thanks,
Sumit Panwar

Title : Re: [directfb-dev] Applying different alpha values for different
regions in the same window
Hi Niels,
I am a beginner to DFB. Could you let me how to set the value of a specified on a surface? For example, can I set the 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

You cannot. Either make multiple windows, or use a per-
pixel-
alpha-value.
