AndyColmes	Posted - Nov 03 2011 : 08:17:13 I know I can adjust the transparency for a layer, but can I restrict it only to a selection if a selection exists?

AndyColmes	Posted - Nov 08 2011 : 08:45:40 Thanks Fabrizio. I will give it a try.
fab	Posted - Nov 08 2011 : 00:49:03 The demo at ImageEditing\Layers shows several layer related features (included layer mask). About the way nr.2, just execute the code shown.
AndyColmes	Posted - Nov 07 2011 : 12:01:09 Thanks Fabrizio. Do you have a demo project on how this is done? I am not sure how to create a layer mask using the bitmap.
fab	Posted - Nov 04 2011 : 07:24:48 There are two ways: 1 - create a layer mask (a 8 bit gray scale bitmap which specifies the upper layer transparency, pixel by pixel) 2 - change the alpha channel of the bitmap For example (2): // set transparency of selected area = 50 ImageEnView1.SetSelectedAreaAlpha(50);
