Abstract:

The DITA OpenToolkit (DITA OT) provides a way to produce multiple outputs, including Portable Document Format (PDF) files; however, the technology for creating PDF files is limited, and modifying the formatting is challenging. This paper explains the alternatives and trade-offs for each method and helps demystify the decision process.
