ACQUISITION METHOD FOR DIVISION AREA SIZE OF DRAWING DATA, AND ACQUISITION DEVICE FOR DIVISION AREA SIZE OF DRAWING DATA

摘要

PROBLEM TO BE SOLVED: To provide a method of acquiring a block size not exceeding a memory capacity of a buffer memory.;SOLUTION: This acquisition method for a division area size of a drawing data is provided with a process (S202) for inputting the drawing data, a process (S208) for dividing a drawing area into a plurality of block areas having the block size, a process (S216) for storing a data volume of a pattern in a cell into a corresponding element of a quad tree, in every cell, a process (S220) for distributing the data volume of the pattern to a corresponding block area, a process (S222) for accumulation-adding the distributed data volume of the pattern in every area, a process (S226) for determining whether an accumulation-added data volume is within the memory capacity or not, a process (S228) for reducing the block size, when not within the memory capacity as a determination result, to feed back a new block size, and a process (S230) for outputting the block size of which the block size is the memory capacity or less.;COPYRIGHT: (C)2010,JPO&INPIT
