now trying to understand images as Mask for transparency.
I set background style as iebsChessboard to see transparency.
loading a png image and psd file as mask. imageen displays correctly but when I save with/without mergeall(true) saved png file does not preserve transparency. what should I do ?
note: I used ImageEnView1.IO.Params.PSD_LoadLayers := False; to not to lose the main image layer before loading psd file as mask
I detected the problem, therefore solved. maybe this may help someone.
problem occurs because of I compiled as 64bit executable. and I forgot to put ielib64.dll in same directory. (without ielib64.dll, problem still exists.) now all worked. thanks sir
