Coherent Graphics Ltd is pleased to introduce a commercial, supported, faster pdf command line tool with the same interface as the popular open source PDFTK tool.
Download the demo here.
- Merge PDFs
- Split into mutiple pages
- Rotate pages
- Decrypt and Encrypt Documents
- Apply background watermarks and foreground stamps
- List and update Metadata
- Attach files to the document or individual pages
For Mac OS X, Windows, Linux, Solaris. Other plaforms by request. Coherent PDF CPDFTK 1.6 is available for $200 for a single license or $40 for a non-commercial use license.
The free trial is fully functional but places the word “DEMO” over any file it writes.
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.
The new version of the Proview PDF Editor for Mac OS X is now available for download. The update is free for existing users – your license key will still work – just download and install from the website.
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.
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.
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:
- Reverse the document’s pages using the ‘reverse’ page specification
- Use the page specification ‘2-end’ to remove the first page
- 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
You can get the Proview PDF Editor at 25% off for the next 16 days at mupromo.com.
We’ve started work on the next release of Proview with an emphasis on making the existing functionality easier to use (visual selection for cropping, for example). Release expected in the Autumn.
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.
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:
We’ve just released the latest version of our PDF Command Line Tools for Windows, Mac and Linux. The tools provide editing of PDF files including merging, splitting, adding text, compressing, encrypting etc.
- Detect missing fonts and low resolution images for pre flight
- Remove embedded fonts for file compression
- Add text diagonally, and optionally relative to cropbox rather than media box
- Copes with malformed PDF files more robustly
- Many speed improvements, especially with large files
A new version of the CamlPDF libraries to reflect the changes with be released soon.
Full details and free trial here.
