Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial application field) The present invention relates to an apparatus for reproducing a vector font by decompressing compressed vector font data. The present invention relates to a character font decoration device having a function of generating a vector font decorative character by filling an inner region surrounded by a circle and an outer region with a decorative pattern specific to the region. (Prior art) In a system that handles dot image data generated based on original images (character fonts) created by designers, the amount of data handled is enormous if the image data is saved and transferred as it is. This causes practical problems in various aspects such as storage capacity and transfer speed. Therefore, data compression means for efficiently storing and transferring the image data is required. As a means for realizing this, a method of scanning an original image such as a character font created by a designer, extracting the outline thereof, and generating vector font data based on the extracted outline dot data is conceivable.
