A method of generating a line part having a thickness D on a homogeneous raster, in which the raster points are arranged in a number of parallel lines, and in which the bit representation of the line part is stored in a word-oriented bit-map memory in the form of a large number of image points or pixels. The method provides for making a determination of the envelope of the line part and imaging the envelope on the raster points. Thereafter, determining the length of the section through the line part for successive raster lines, and placing the bit representation of said lengths in the bit-map memory at corresponding locations, so that the direction of the determined lengths corresponds to the word direction of the bit-map memory.
