Answer 1

Explanation:

difference between raster graphics and vector graphics :

Raster graphics:

• they are composed of pixels .
• In raster graphics, refresh process is independent of the complexity of the image .
• graphic primitives are specified in terms of end points and must be scan converted into corresponding pixels .
• Raster graphics can draw mathematical curves , polygons Saint boundaries of curved primitives only by pixel approximation.
• raster graphics cost less .
• they occupy more space which depends on image quality.

vector graphics:

• they are composed of paths.
• vector displys flicker when the number of primitives in the image becomes too large.
• Scan conversion is not required.
• vectors graphics draw continues And smooth lines.
• vector graphics cost more as compared to raster graphics
• they occupy less space.
