If you have a "round look", you must have a circle/oval shaped bitmap (square of course, but objects are not)?
The quickest way I do is click "Edit Bitmap" which opens Photo Paint. Ctrl+A to select all, then menu Mask --> Mask Outline --> Feather, and feather an appropriate amount. Click X to close PP, yes to save, and it's feathered/faded in Corel Draw.
If it's a bitmap consisting of circle OR odd-shaped objects, I would just add a mask to the outer objects in PhotoPaint, which is pretty simple, then do the same thing.
