Abstract:
1. An image processing apparatus for generating scaled image data that is obtained by scaling the image data according to a specified scaling factor, the image processing apparatus comprising: an image data input section that receives input of image data described in a page description language; a page description language processing section that converts the page description language input image data; a receiver that receives an input of pixel value information of each pixel which is contained in the converted image data to be processed in raster scan order; a first memory that stores the pixel value information input in the raster scan order, a maximum capacity of the first memory being less than a memory capacity needed to store the pixel image data of a full scanning line in a main scanning direction; a second memory that retains the scaled image data of an entire scanning line's worth of pixel data and the scaled image data of a plurality of subscanning lines relative to a subscanning direction; a destination address generator that generates destination address information in the second memory to specify a destination location of the pixel value information stored in the first memory in response to the specified scaling factor; and a transferring unit that transfers the pixel value information from the first memory to the second memory based on the generated destination address information.
