ABSTRACT:
A character pattern generation apparatus for a serial printer, comprises an input buffer for storing a character code and attribute data; contour data storing means for storing contour data representing a contour of a pattern correspondingly to the character code, the contour data including starting point coordinate data, end point coordinate data, and line type data; means for reading the contour data from the contour data storing means according to the character code stored in the input buffer; operation means for calculating new starting point coordinate data and new end point coordinate data, according to the degree of magnification which is designated by the attribute data, the starting point coordinate data and the end point coordinate data, to output coordinates of a starting point and coordinates of an end point, the starting point and end point being in a current pass area; contour reproducing means for joining the coordinates of the starting point with the coordinates of the end point output from the operation means by a line the type of which is designated by the line type data, to reproduce punctual coordinates of a contour; and means for converting the punctual coordinates of the contour from the contour reproducing means into bit data to output the converted bit data.
