If your application needs more PDF functionality than the Glyph & Cog libraries provide, an Xpdf source license is the solution. With a source license, you'll have the ability to directly use the Xpdf source code in your application.

Xpdf includes:

• a core PDF engine, responsible for reading PDF files
• a flexible "backend" abstraction, using a device driver-style interface
• backends for rasterization (generating in-memory bitmaps), PDF-to-PostScript conversion, and PDF-to-text conversion

Xpdf is a modular C++ application. The code is portable and is known to compile under Microsoft's VC++, GNU gcc, and major Unix vendors' compilers.

The Xpdf backend interface is flexible, and can easily be adapted to your application, whether it's a custom viewer, conversion tool, or something completely different.

Additional Components

There are a few modules which are not part of the open source Xpdf releases, but which are available for licensing. Please Contact us if you are interested in any of these.

WinXpdf is all of the Xpdf code, plus the Windows-specific viewing and printing code.

A DeviceN rasterizer add-on is available. This extends the Xpdf rasterizer to support DeviceN (CMYK + spot colors) output, including overprint capability.

Additionally, we can provide consulting services to help you integrate Xpdf with your application. Contact Glyph & Cog for more details.
