Posted - Nov 30 2022 : 19:55:49 Hi Nigel, For the CropSel(true) function, I don't need to set the alpha channel. It looks like the CropSel(true) function sets the alpha channel itself. Perhaps it would be more correct for the ClearSel(true) and CropSel(true) functions to work the same way with the alpha channel. Thank you.

You need to ensure the image contains an alpha channel:
ImageEnView1.IEBitmap.AlphaChannel; // Ensure image contains an alpha channel
ImageEnView1.Proc.ClearSel(true);
