发明名称 ELECTRONIC DATA COMPRESSION DEVICE, ELECTRONIC DATA COMPRESSION METHOD, PROGRAM AND STORAGE MEDIUM
摘要 <P>PROBLEM TO BE SOLVED: To make it possible to create highly compressible electronic data without deteriorating quality levels of characters or losing character attributes of characters. <P>SOLUTION: A CPU 1 of an information processor registers, when an attribute of an object is a font a discrimination ID thereof in a font identification table. The CPU determines, when the object has image or graphic attribute, whether it overlaps with an object having identification information registered in the font identification table or not. When the overlapping exists, the discrimination ID of the image or graphic object is registered in the font identification table. An image or graphic object whose discrimination ID is not stored in the font identification table is developed with high compression setting to form a first layer. An object whose discrimination ID is stored in the font identification table is developed with low compression setting to create a second layer. <P>COPYRIGHT: (C)2008,JPO&INPIT
