Abstract:
A print apparatus and print method are provided in which the efficiency of a raster operation is improved according to destination images. The print method includes the steps of extracting a source image, a halftone image and a destination image from an image to be printed, determining an attribute of the destination image and converting raster operations (ROPs) of the source image, the halftone image and the destination image in accordance with the determination result, and performing the converted ROPs. If the attribute of the destination image is a written state, the conversion of the ROPs may be omitted, and if the attribute of the destination image is an initial state, the ROPs may be converted to more simplified operations using an initial state value of the destination image. Accordingly, by determining an attribute of the destination image D in advance, before the ROPs are performed, and converting the ROPs to simplified ROPs, the time required for rendering a result can be reduced and an entire printing time can be reduced.
