PURPOSE:To utilize a general character pattern file by performing variable power processing for character pattern images which are read out of a character pattern file in order according to control file information. CONSTITUTION:This method is provided with the character pattern file 1 containing character patterns and the control file 2 consisting of header parts such as identifiers and enlargement/reduction control records. A display and printing control processor 3 determines the positions of repetition and deletion of a raster and a column in the scaling file 2 according to the difference in dot size between character pattern of output size and patterns in the character pattern file and varies the power of a raster image successively read out from the character pattern file 1 according to control information obtained by above- mentioned processing. Further, the raster image after the processing is written in an image buffer memory 4 at a specific position, read out in order, and outputted on a display device 5 or printer 6. |
