Question

What is the purpose of anti-aliasing in bitmap displays?

a.

To increase the number of colors that can be displayed

b.

To increase the brightness of the display

c.

To soften the edges of line segments and make the rough edges caused by pixel approximation less obvious

d.

To decrease the resolution of the display

Posted under Human Computer Interaction

Answer: (c).To soften the edges of line segments and make the rough edges caused by pixel approximation less obvious Explanation:Anti-aliasing is a technique used in bitmap displays to reduce the problem of 'jaggies', or rough edges, caused by the attempt to approximate lines and curves with pixels. Anti-aliasing works by softening the edges of line segments, effectively blurring the discontinuity and making the jaggies less noticeable.
