PDFlib pCOS provides a simple and elegant facility for retrieving any information from a PDF document which is not part of the page contents. For example, PDF metadata, interactive elements (links etc.), or page dimensions can easily be queried with pCOS.

With pCOS you can extract a variety of interesting items and create output for different purposes. By processing multiple PDF documents with a single call you can easily create summaries of document info entries, page formats, fonts, or any other property. Combined with tabular output this provides a powerful PDF administration tool.

There are many every-day pCOS applications for PDF practitioners, but you can also use PDFlib pCOS as a tool for learning or debugging PDF. Here are some typical scenarios:

• Check incoming documents for predefined criteria
• Check PDFs for security problems and active content (Java-Script etc.)
• Check documents for quality assurance before publication
• Identify problem files in a large collection
• Create property summaries for document management
• Learn details of PDF data structures

Note: Please review the following Platform and Product Requirements, Limitations of the Evaluation version and Supported Programming Languages before downloading or purchasing this software.

• User-defined output formats for custom post-processing

pCOS Paths - Simple Syntax for PDF Objects Instead of getting bogged down by complex tree structures, e.g. for bookmarks or form fields, you can easily access PDF objects by using the simple pCOS path syntax. It offers convenient shortcuts for accessing commonly used PDF objects, such as pages, fonts, bookmarks, form fields etc.
