That's called a transparent gif or transparent png. I'm sure you can make it with Corel.
Usually when I export an image, the whole background gets exported too, which is usually fine except in some cases like mine right now: I'm trying to slap the logo onto a slideshow movie and each slide already has their background image.
I don't want to place a bland white square on anywhere of the screen to make the slideshow look messy.
Anybody got an excellent idea?
BTW. The slideshow is created by Corel VS.
