ABSTRACT:
A character pattern generator includes a ROM for storing font data and attribute information of each point of each stroke forming the font data, and a CPU for recognizing a portion to be transformed of a contour shape of the stored font data based on the attribute information of each point. The CPU further adds to the recognized portion to be transformed, a control point for performing transformation into a character pattern having a specified typeface code. The CPU then calculates the coordinates of the control point based on a factor at each point of each stroke of the font data. The CPU then transforms the contour shape by using the added control point and the font data. Finally, the CPU generates the character pattern having the specified typeface code based on the contour shape of the transformed font data.
