Instead of low-quality screen-shots a PDF to get the images, use Poppler to extract the original high-resolution images from the PDF. Note: only raster images can be exported with Poppler.
Examples of PDF image extraction tasks:
List all PDF images
pdfimages -list in.pdf
Extract PDF images from all pages: dumps all images in
mydoc.pdf to the same directory.
Filenames start with

pdfimages -all in.pdf out
