Hello.
I am uploading a jpg image.
I use 
IEV_Load.Proc.ClearSel(true);

The function does not make the background transparent.
But.
I am uploading a jpg image.
First I apply 
IEV_Load.Proc.CropSel(true);

and then 
IEV_Load.Proc.ClearSel(true);
the background will be transparent.

You can do 
IEV_Load.Proc.ClearSel(true);
made the background blank from the first application.
Thank you.

Hi Rudolf

You need to ensure the image contains an alpha channel:

ImageEnView1.IEBitmap.AlphaChannel; // Ensure image contains an alpha channel
ImageEnView1.Proc.ClearSel(true);

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.

Hi Rudolf

Yes, that is true. We will implement that.
