In Corel® PHOTO-PAINTTM, select any object (other than the background) and copy it to the clipboard by pressing Ctrl+C. Right-click the same object and click Create Clip Mask > From Object Transparency.

With the clip mask selected (active state is indicated by a red border in the Objects docker), click Edit > Paste > Paste as New Selection. Now you have the darker areas of the object transparent and the lighter areas opaque. By the way, this is also a useful method for creating your own brush nibs.
