Patent ID: 6919968

Claim:
A method for processing image data, comprising the steps of: defining a presentation of respective source picture elements by a source image to be processed that contains source picture elements arranged matrix-like to which respective source image data is allocated; determining a presentation of respective target picture elements by a target image arising in processing that contains target picture elements arranged matrix-like to which respective target image data is allocated; the source image having a first resolution corresponding to a source raster and the target image having a second resolution deviating from the first resolution and different by a conversion factor that corresponds to a target raster, said target image has a higher resolution than said source image, said source image and said target image being binary images; subdividing the source image into source sub-images arranged matrix-like; arranging a respective target sub-image at a position in the target image that coincides with a position of the appertaining source sub-image in the source image; and performing a conversion such that a line having a non-whole-numbered line width is presented in the target raster in that it is thinned in the target raster.
