Grim

Ruby gem (using ImageMagick and Ghostscript under the hood) that extracts a PDF page as an image — PNG or similar — or as page text, reports total page count, and iterates all pages in batch, with configurable image width/density/quality/colorspace/alpha and custom processor paths. Its text extraction is a thin wrapper around `pdftotext` rather than an independent implementation, so text-extraction fidelity matches whatever Poppler already produces.
