Image cut out

[Bthnt]

Dearest Forum:

 

I use paint.net as a tabletop RPG platform.  When I add images to my scenes, I often find myself LABORIOUSLY erasing away the background they came with.  I know there is an algorithmical way of doing this... what am I missing? 

 

Thanks,

Try AlphaSpace if the background is a uniform white or black.

 

Alternatively (if the background is non-uniform, and composed similar shades), Magic wand & the delete key.

 

Remember to save the file in a format that supports transparency (like PNG). JPGs in particular often interpret transparency as a solid black or white.

Depending on what the foreground & background image is, I find that https://www.remove.bg/ or https://photoscissors.com/ generally does an accurate and very fast job.
