Abstract
The surface parts of an image which is stored in the form of a bit-representation in a raster image memory may be filled with a surface pattern using the following steps: generating a bit-representation of the surface pattern defined uniformly over the entire image surface; generating a mask function, which gives a specific logic value to those raster points which are situated within the boundaries of the surface parts; generating a filling pattern by performing a logic operation on the bit-representation of the surface pattern and the mask function; and transferring the filling pattern to the raster image memory.
