The major adverse side effects of scan conversion are ;-

A. Staircase appearance

B. Unequal brightness of slanted lines

C. Picket fence problem

D. Rasterization

E. Pre-filtering and Post-filtering

Choose the correct answer from the options given below:

The correct answer is Option 2.

Key Points

• The major adverse side effects of scan conversion are:
  • Staircase appearance: This is a visual artifact that occurs when diagonal or curved lines are rendered as a series of small steps, rather than smooth lines.
  • Unequal brightness of slanted lines: This effect happens when the brightness of slanted lines is not consistent, often due to the way pixels are illuminated on the screen.
  • Picket fence problem: This is an issue where alternating lines or patterns are not displayed correctly, resembling a picket fence.

Additional Information

• Rasterization: The process of converting vector graphics into a raster image (pixels or dots).
• Pre-filtering and Post-filtering: Techniques used to improve image quality before and after scan conversion.
