ITPEC IP October 2019 — Question 25 of 100
Raster graphics store an image as pixels, so the color and brightness can be adjusted independently for each pixel. This representation is well suited to photographs and painting effects with detailed local color variation.
Answer (b)
Why not others:
- CAD commonly relies on vector graphics for precise scalable geometry
- raster file size generally grows with resolution and color depth before compression
- enlarging a raster image exposes pixels and can produce jagged or blocky edges
Key rule: Raster images are resolution-dependent pixel grids; vector images describe geometric shapes and scale more cleanly.
