PDFlib is a development tool for PDF-enabling your software, or generating PDF on your server. PDFlib offers a simple-to-use API for programmatically creating PDF files from within your own server- or client-side software.
PDFlib doesn't require any other tools and doesn't make use of third-party software for generating PDF.
Here are some key features of "PDFlib":
· PDF/A for archiving: PDFlib can generate output according to the PDF/A-1a and PDF/A-1b standards, formally known as ISO 19005-1. PDF/A specifies a standardized subset of PDF for long-term preservation and archiving of PDF documents.
· Table formatting: new table formatter which automatically places rows and columns, and splits tables across multiple pages.
· 3D animations: 3D animations in the U3D format can be embedded in the PDF output. Actions can be defined to interact with 3D animations
· AES algorithm: PDFlib supports 128-bit encryption with the AES algorithm (Advanced Encryption Standard)
· Integrated pCOS: PDFlib+PDI now includes the pCOS 2.0 interface. It can be used to query arbitrary properties of an existing PDF document via a simple path syntax.
· XMP metadata: PDFlib automatically creates XMP metadata from document info fields.
· XMP extension schemas for PDF/A-1 with full validation
· Layers: important for CAD and engineering applications; all layer control features available in PDF 1.5;
· Text formatting: automatic multiline formatting; Unicode text, ragged or justified text, arbitrary font changes, multi-line body text or large tables. Blocks with multi-line text and reflow.
· Tagged PDF: accessible PDF according to section 508
