Abstract
A method of extracting a section of a page from a portable document format file (“pdf”): The method includes receiving indication of a user-defined region on a pdf file page, designating an extraction region including all elements determined to be within the user-defined region, and placing the extraction region into a new file. The method may also include determining if one or more elements on the pdf page are within the user-defined region by applying inclusion rules based on whether an element's bounding box is within or intersects the user-defined region. The method may also include verifying the accuracy of the extraction by converting the user-defined region in the original pdf document and the extracted region to bitmap images and comparing the two bitmap images, bit by bit.
