This concise book provides a hands-on tour of the world’s leading page-description language for programmers, power users, and professionals in the search, electronic publishing, and printing industries. Illustrated with lots of examples, this book is the documentation you need to fully understand PDF.

  • Explore PDF operators for building and showing text strings
  • Get up to speed on bookmarks, metadata, hyperlinks, annotations, and file attachments

Commercial, Supported, Faster PDFtk – Beta Testers Wanted

Posted on November 8, 2010 by coherent

We’re writing a front end for our PDF tools with the same command line interface as pdftk, so that it can be used as a drop-in replacement for pdftk for people who can’t compile pdftk on their system and don’t want to change to our normal command line system cpdf, or who want a supported, commercial pdftk.

We’re looking for people who used pdftk regularly, either manually or as part of automated systems, to join in testing.

If you’re interested please use the contact form on the front page at http://www.coherentpdf.com/ and send a couple of sentences about how you use pdftk.

Removing the Last Page from a PDF

Posted on April 9, 2010 by coherent

A customer recently asked how to do this. The Coherent PDF Tools page specification doesn’t directly allow it, but we can do it indirectly:

  1. Reverse the document’s pages using the ‘reverse’ page specification
  2. Use the page specification ‘2-end’ to remove the first page
  3. Reverse the document again
You can use the ‘AND’ construction to string these together in a single command, avoiding processing the file multiple times:

cpdf in.pdf reverse AND -range 2-end AND -range reverse -o out.pdf

GraphPDF: A PDF Version of Ocaml’s Graphics Module

Posted on April 3, 2010 by coherent

I’ve written a version of Ocaml’s Graphics module which outputs PDF directly, using the CamlPDF library – its only dependency. It’s based on the approach of Pierre Weis’ GraphPS program.

It has the same API as Ocaml’s module – just have your build process find the GraphPDF files before it finds the system ones – the vast majority of programs shouldn’t need altering.

Get it here.
