Sample-based
(raster, paint)
Pros and Cons
•Pros
–Photographic realism
–Variations of colors within area
–Able to (somewhat) simulate
many traditional media (paints, markers, etc.)
–Supports actions like “smudging”, blurring etc.
•Cons
–Objects have no memory/definitions—can’t select them and move them around (at least not easily, and a moved object leaves a hole in the image)
–Large file size
–Filtering and other operations computationally intensive—can be slow
–Fixed scale (pixel dimensions of image)
