About
A frame that allows you to display an image or even a PDF file semi-transparently. It makes it easy to copy, trace, or compare drawings, images, and documents because the frame can be locked to resist mouse gestures.
This is a transparent overlay of an image or document on the screen that you can click on - like a transparent sticker on the screen.
Overlay is especially useful for artists, designers, and students to create their own artwork or design based on or referenced from photos and screenshots.
