I\'ve read much about PDF extractions and libraries (as iText) but i just haven\'t found a solution to extract images and text (with coordinates) from a PDF.
It can extract all the characters in the PDF with co-ordinates (pdftotext -bbox [sourcefile] [outputfile]) and also all the images and SVGs in the PDF.
It's open source (GPLv2) and supports a lot of additional extraction functionalities as well.
