Abstract
Conventionally, pixel data are converted into the tile sequence. According to this invention, span information or run-length information during conversion into pixel data from vector data such as a display list converted from a page description language is converted into the tile sequence before rendering into pixel data. This can greatly reduce the amount of data temporarily stored for conversion into the tile sequence.
