摘要

PURPOSE: To mix text data and image data displayed by a graphics command by rasterizing text character data by using a stored raster font by a printer and rasterizing graphic image data from a formed and stored raster image. CONSTITUTION: The data related to a printed page 21 is shown by conceptionally bonding a zone line to the rasterized bit map memory of a page printer. In a zone line structure, the zone lines of all of bit maps showing the page 21 are not present in a bit map memory of course at the same time. The command of the plotter arranging a line 24 on the page 21 at the proper position of the bit map memory is received by the printer mixed with text data and interpreted in a text environment to be rasterized.
