SourceForge.net: Project Info – PdfRipImage Mar 19 2005
We’ll probably check this out for a project where we’re going to be working with a lot of PDFs (I want to thumbnail the first page and show it on a web page). Although it does sound a little like maybe this script just extracts _images_ from a pdf instead of creating an _image_ from the total contents of the pdf.
PdfRipImage is a shell script to automatically extract images from PDF documents and convert them to a format of your choice (such as JPEG or TIFF). It runs on UNIX-like platforms and requires utilities from netpbm and xpdf.
