Abstract:
A resolution conversion module for converting a resolution of image data, comprising the steps of:receiving information representing resolutions before and after conversion from a printer driver;calculating a magnification or reduction value for each pixel of an original image before conversion on the basis of the received information;receiving information of a processing region, which is segmented with reference to an image size after conversion, from the printer driver;obtaining a region on the original image before conversion corresponding to the segmented processing region on the basis of the magnification or reduction values for pixels;passing information of the obtained region on the original image before conversion to the printer driver;receiving original image data of the obtained region from the printer driver;changing a size of the received original image data on the basis of the magnification or reduction values for pixels; andpassing the data of the region after resolution conversion to the printer driver.
