<p>In a method for obtaining drawing point data used for drawing an image on a substrate (12), drawing point data that has the feature of images, and of which the data volume can be reduced, is obtained. An address in a memory, at which image data representing an image corresponding to a drawing start position of each of drawing point formation units (38) is stored, is obtained as a readout start address of each of the drawing point formation units (38). Drawing point data for each of the drawing point formation units (38) is obtained by sequentially reading out image data from respective readout start addresses along the respective drawing point data paths in image data corresponding to the drawing path of each of the drawing point formation units on the substrate (12). Run-length compression is performed on the obtained drawing point data in two-dimensional directions, for example.</p> |
