The present invention relates to a method and an apparatus for extracting images from a PDF document, and a recording medium and, more specifically, to a method and an apparatus for converting vector images drawn by a rendering algorithm inside PDF into raster images and extracting, from a PDF document, the vector images converted into the raster images as well as raster images, and a recording medium storing the method. The method for extracting images from a PDF document according to the present invention classifies a plurality of image existing on a PDF document into raster images and vector images, extracts the raster images and the vector images from the PDF document in pixel units, rasterizes the vector images to convert into raster images, determines whether any extracted image completely includes an extracted different image, and groups the extracted raster images or vector images automatically or manually according to the determination results to integrate into a raster image. |
