Abstract
For image parts in an image with large circumscribed quadrilaterals, one-dimensional data development is executed where intersection point data on a scanning line are accumulated for plural image parts and one-dimensional raster data of the scanning line is produced based on the intersection point data. For image parts with small circumscribed quadrilaterals, two-dimensional data development is executed where intersection point data in an image part are obtained and two-dimensional raster data of the image part is produced. While the one-dimensional data development requires only a small memory capacity for raster data creation even for relatively large image parts, the two-dimensional data development allows high-speed raster data creation for relatively small image parts.
