Portable RTF support bulletin

How it works

1. Format the headings

   Apply font size, bold text, color and paragraph spacing through the native RTF paragraph and run APIs.

2. Write the diagnostic sequence

   Add the symptom, an ordered sequence expressed as bullets and a table describing useful evidence.

3. Save and reopen the RTF

   Serialize the document, then let the runner load the saved RTF and convert it to PDF.

This is the complete example file used to generate the download. The walkthrough runner creates the output directory and produces the additional previews.

using OfficeIMO.Rtf;
