Assets for wkhtmltopdf margin + link debugging.

The goal of these assets is to show what happens to a working link in the footer of a generated PDF based on the presence of margins.


  • wkhtmltopdf v0.12.3
  • debian jessie 64-bit
  • page.html + page_footer.html assets

The execution examples should provide two results for comparison. The result generated without margins contains a link in the footer that works as expected. The result generated with the margins exposes the issue described in this issue (1), the link element roughly 0.5" above the linked text.

View Cargo guide

The guide is very informative and left me with very few questions!


  • Excellent job showing what happens with cargo build execution.
  • Same for cargo run and inclusion of the --release flag.
  • Good descriptions of the purpose and concerns of the Cargo.toml and Cargo.lock files.
  • Noted when to include Cargo.lock in the repo: yes for apps, no for libs (similar to Gemfile.lock in Ruby apps/gems).

Maybe helpfuls:
