I have a background image with linear transparency applied on the top of my image. I would like to replicate the same transparency on the bottom of the image. How can I do this?
Yes, we can do this. Click on the image and then click on interactive transparency tool.
After that, click on edit transparency on the top left corner
I can't answer specifically for Corel Draw, but in other vector software, what I'd usually do is use an object on top that has a gradient.
So, I'd place a square shape on top of the map, and then use a gradient of white->transparent->white
Granted, that only works if you intend to have a white background at some point.
