Question

How does run-length encoding compress bitmaps?

a.

By giving short codes to frequent words

b.

By representing long runs of the same value with length value pairs

c.

By computing the difference between successive frames

d.

By storing only the differences between successive frames

Posted under Human Computer Interaction

Answer: (b).By representing long runs of the same value with length value pairs Explanation:Run-length encoding compresses bitmaps by representing long runs of the same value with length value pairs. For example, a sequence of repeated white pixels could be represented as "10 white pixels" instead of storing each individual white pixel separately.
