Method for converting the number of bits of input bit stream |
摘要 |
An image scaling method and apparatus partitions each line of image pel (print element) indicating bits into a number of bit groups equal to the number of bits to be added or deleted from the line to achieve a desired scaling. In each of the bit groups, one pel is added for enlargement or one pel is deleted for reduction. The pel addition or deletion occurs at pairs of like-pel indicating bits. If any bit groups has no pairs of like-pel indicating bits, a pel indicating bit is added for enlargement or deleting for reduction in an arbitrary location in the bit group.
