A new version of our PDF Editor for the Mac will be launched next week. New features include Visual Crop and the setting of crop and trim boxes on individual pages. It’s also about twice as fast as before.

It’s not too late to join the beta program – just sign up with MacDeveloper.net. Proview 1.2 will be a free upgrade for existing users.

Removing the Last Page from a PDF

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

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.

CamlPDF 0.5 Released

I’m pleased to announce the CamlPDF 0.5 release, which includes a couple of new modules (Pdfdate for date manipulation, Pdfannot for annotations and Pdfmarks for bookmarks). Almost every other module has been improved in some way.

Download it here: http://www.coherentpdf.com/ocaml-libraries.html

More importantly, I’ve finally found time to write a short introduction to CamlPDF, which lets you try some basic work within the OCaml top level:

There have been some API modifications which are not backward compatible, but the changes to your source are easy to make. This should be the last release with such changes.

There is now a CamlPDF mailing list:

Beta Testing with MacDeveloper

We’re well into the first testing cycle for Proview now. We’re using MacDeveloper, which automates the process somewhat, and has a group of about 8000 people signed up for testing, giving them discounts or free copies of the software when they’ve submitted enough acceptable bug reports to the ticketing system.

MacDeveloper runs with its own ticketing system, but the data can be exported to CSV. Haven’t worked out how to get it into bugzilla yet, though.

I’m happy with how few crash/freeze bugs have been reported, and the complaints about the interface seem to crystallize around a couple of issues – so we’ll re-jig it before the next release.

Here and here are a couple of articles on contemporary beta testing.
