<p>The invention is related to a method for converting a series of drawing instructions suitable for assigning pixel values corresponding to said drawing instructions to pixels positioned in an image arranged in rows and columns of pixels, to a series of runlengths and corresponding pixel values. A runlength hereby represents the number of successive pixels with mutual identical pixel values while the series of runlengths and pixel values is arranged according to a first order as determined by successive pixel positions. First the runlengths of the pixel values as generated by the drawing instructions are determined in a second order which is different from the first order. Consequently, the insert positions of said determined runlengths are determined on the basis of pixel positions which are corresponding with said determined runlengths. On the basis of these insert positions, said deteremined runlengths are inserted in the series of runlengths according to an prescription for inserting whereby runlengths in the series which have positions in common with said runlengths to be inserted, are modified in dependance on the said runlengths and pixel values to be inserted. <IMAGE></p> |
