How to obtain the transparent area under the bent part of the page?
Fig.1
Note! The backdrop that is used in the plug-in has NO relation to the type of the active layer, because is used ONLY for
indicating the transparency under the curled (folded) parts in the Main Preview area of the plug-in
(See Fig.2).
The transparent area under the bent (curled and/or folded) part of the page is generated automatically, just be sure that the active layer is not
the background layer or the layer with the protected transparency (See Fig.1).

If you need to keep the obtained image for further usage, then you should use the saving options of the host and save the obtained document as PSD, PNG, or
any other file formats, which let you keep the transparency.

You may ask - what will happen, if the active layer is the background layer or the layer with the protected transparency?
The answer is simple - in this case the area under the bent part will be filled with a background color that is specified in your host (See Fig.3).
