Answer:
A vectorizing represent an image using lines to construct the outlines of objects.
Explanation:
Vectorization or tracing is the process of taking a bitmap image and re-drawing it as a vector image. The shapes in vector images allow computers to do things that cannot be done with bitmap images, like scale them to any size without loss of quality and using them to e.g. cut, sew, paint, and laser engrave.
It is the border that is around the original art piece itself. So the artwork is either placed on a board that is then cut 1/2 an inch around the artwork itself. Or in other cases the canvas, paper, etc is masked off 1/2 an inch around the edge of the paper.
Hope this helps!
