The PDF files do not contain any images (except for the thumbnail images). The scanned image has been converted a vector format by drawing lots of closely spaced parallel lines. You can see this if you zoom in on the page. I assume this is for printing on a pen plotter. You can create an image from each PDF page with pdftoppm. After converting to PNG this results in a much smaller and faster to render image but it does lose the shading effects that were created by the hatching. _______________________________________________ poppler mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/poppler
