PROBLEM TO BE SOLVED: To quicken plotting, and to reduce a storage capacity necessary for plotting. SOLUTION: When pictures are plotted by calling a function prepared for an operating system from an application, data from the application are converted into data for a device driver prepared for each kind of picture outputting devices so that the pictures can be plotted by the driver by the operation system. At that time, when a multilevel brush is used as a brush for painting out the inside part of a graphic for each device, and it is not influential to convert the multilevel brush into a binary brush (step 1-4: YES), the transferred multilevel brush is converted into the binary brush by the printer driver (step 1-5). |
