I think the 'mask' value might help.... var mask = 0x00FF0000; bmd.threshold(bmd,bmd.rect,new Point(),">",0x00000000,mono_color,mask); this code is not tested, but something like this , It worked for me when I was trying something very similar, and whatever it was , I gave up around the time that I was trying to make something just like this function that finds the first non transparent pixel ! wow thanx great help for this!

bmd.threshold(bmd,bmd.rect,new Point(),”>”,0×00000000,mono_color,mask);
