Abstract
A disclosed method for extracting a raster image of a page from a portable electronic document that includes (a) acquiring commands and resources of the raster image of the page by analyzing a format of the portable electronic document, (b) extracting first and second candidate raster images by processing the commands and the resources of the raster image of the page, (c) integrating the first and second candidate raster images as an integrated candidate raster image provided that the first and second candidate raster images are linked together, and (d) removing a pseudo-raster image from the integrated candidate raster image.
