Features
The converter:
- Extracts YAML front-matter — uses
title,date,version,audiencefor the title page - Generates a title page — with project name, subtitle, date, version, and audience
- Generates a table of contents — built from H1-H3 headings
- Embeds PNG images — resolves
references relative to the input.mdfile, reads the PNG, and embeds it inline in the Word document - Styled output — Calibri font, colored headings (
#1F3864), styled tables with alternating row colors, code blocks in Consolas - Handles all Markdown elements — headings, paragraphs, tables, code blocks, lists, images, links, horizontal rules
Image Embedding
The converter automatically embeds PNG images referenced in the Markdown:
The image path is resolved relative to the input Markdown file. The PNG is read, dimensions are extracted from the PNG header, and the image is scaled to fit within 6 inches width while preserving aspect ratio.
If an image file is not found, a placeholder [Image not found: <path>] is inserted.
