Getting Started

Install with:

remotes::install_git("https://korap.ids-mannheim.de/gerrit/IDS-Mannheim/posterdown")

Now add this to the YAML options of your rmarkdown (.Rmd) file:

---
output: 
  posterdown.ids::posterdown_ids
---

For further customization options please see the (currently in progress :hammer:) wiki

Additional metadata / customization for IDS version, e.g.:

Use without R for plain markdown

Install pandoc, create a simple poster.md file, for example:

Then run the following command:

pandoc poster.md --to html4 --from markdown+autolink_bare_uris+tex_math_single_backslash --wrap preserve --section-divs --template https://gitlab.ids-mannheim.de/ids/posterdown/-/raw/master/inst/rmarkdown/templates/posterdown_ids/resources/template.html?ref_type=heads --highlight-style pygments '--mathjax=https://mathjax.rstudio.com/latest/MathJax.js?config=TeX-AMS-MML_HTMLorMML' --citeproc --output poster.html

View the resulting poster.html in your browser and print it as a PDF (don´t forget to tick print backgrounds and possibly select only the first page).

Alternatively, ci/html2pdf converts the HTML to an A0 PDF with exact dimensions and automatic hyphenation:

ci/html2pdf poster.html poster.pdf

Printing on fabric

When printing on light fabric, solid black tends to bleed out, making QR codes hard to scan and text fuzzy. ci/pdf-lighten-black produces a variant of a finished PDF in which all vector black is replaced by a dark grey (default 10%, configurable), while text and graphics stay vector and embedded raster images are untouched:

ci/pdf-lighten-black poster.pdf poster_fabric.pdf        # 10% grey
ci/pdf-lighten-black poster.pdf poster_fabric.pdf 0.25   # lighter, if black still bleeds

For mounting, pdfjam can place that A0 fabric version on a page which is 2 cm wider and taller, leaving a 1 cm margin on every side:

pdfjam poster_fabric.pdf \
    --papersize '{861mm,1209mm}' \
    --noautoscale true \
    --outfile poster_fabric-1cmborder.pdf

The CI workflow builds both variants automatically as target/skeleton_fabric.pdf and target/skeleton_fabric-1cmborder.pdf.
