Abstract
Abstract An apparatus for adjusting a line width of an outline font includes an original outline data storing device for storing attribute data in advance. The attribute data indicates whether a data point, which represents a contour line of a character of an outline font, is a point at which line width is to be adjusted. The attribute data is stored in correspondence with original coordinate-value data of the data point. Also provided is an original line-width data storing device for storing data representing original line width in correspondence with original outline data of each character; and a line-width converting device for converting original line-width data into fraction-processed output line-width data in conformity with a mesh size corresponding to a designated character size. A coordinate-value converting device, which is operative when original coordinate-value data read out of the original outline data storing device is accompanied by attribute data indicating that line width is to be adjusted, converts the original coordinate-value data into fraction-processed output coordinate-value data using the fraction-processed output line-width data such that a line width stipulated by the fraction-processed output coordinate-value data becomes equal to a line width represented by the fraction-processed output line-width data.
