I am taking several bitmaps and drawing them onto a picturebox with a low opacity so that all of the bitmaps can be seen together as one picture.
My problem is that any time I need to re-draw this "final combined image", I have to put all of the pictures on top of each other again, which is slow when you're dealing with 100+ bitmaps.
How might I be able to draw each bitmap (with opacity) onto a new "final bitmap" rather than onto the picture box so that I can just paste in the final result quickly?
