If vector system block sequence conversion processing is applied to page image data with a large number of drawing objects, then the conversion processing can be performed, but the memory size of the work buffer is significantly increased
Solution Approach 1:
The patent segments the work buffer into multiple regions: a first work buffer for storing line sequence data, a second work buffer for storing block sequence data, and a third work buffer for storing converted block data. This segmentation allows the system to process data in smaller chunks rather than loading all data into a single large buffer, thereby reducing the peak memory requirement while maintaining processing capability for pages with many drawing objects
Solution Approach 2:
The patent performs preliminary conversion of line sequence data to block sequence data in the first and second work buffers before final rendering. By pre-converting data to the block sequence format needed for efficient parallel processing, the system avoids needing to hold all original line sequence data in memory during the conversion process, thus reducing the required work buffer size
