Abstract
A method for producing compressed or expanded images is provided. For compression or expansion in a direction of the lines of the image, a line factor is determined as a starting value for a line variable. After this, the following steps are carried out cyclically: if a momentary value of the line variable is greater than zero, the source image data being processed is copied and used as a target image data Next, the momentary value of the line variable is reduced by a numerical value. If the momentary value of the line variable is not greater than zero, the next source image data is used in the place of the source image data being treated. Then the value of the line factor is added to the momentary value of the line variable. A column based expansion or compression is also provided for expanding or compressing an image in the direction of the columns. A circuit is provided for performing the expansion or compression, and a printer having the circuit is also provided.
