PROBLEM TO BE SOLVED: To solve such a problem that it is difficult to accurately generate properties by pixels when a drawing based upon a drawing instruction accompanied with logical operation processing specification is carried out. SOLUTION: This image processing method for generating bit map data and property information by pixels corresponding to the bit map data by expanding the drawing instruction has an operation determining process of determining operation contents for the property information according to the logical operation processing specified by the drawing instruction, a logical operation generating process of generating logical operation processing for the property information according to the determined operation contents, a logical operation process of generating the property information by executing the logical arithmetic processing for the property information, ad an inverting process of inverting the property information when the property information has an inversion property. Consequently, the accurate property information can be generated and color processing of high quality corresponding to the properties can be performed. |
