Extract TikZ Diagrams to SVG
Extract TikZ diagrams from the Beamer source, compile to multi-page PDF, and convert each page to SVG for use in Quarto slides.
Steps
Step 0: Freshness Check (MANDATORY)
Before compiling, verify that extract_tikz.tex matches the current Beamer source.
- Find the Beamer source:
ls Slides/$ARGUMENTS*.tex - Extract all
\begin{tikzpicture}blocks from Beamer - Compare with
Figures/$ARGUMENTS/extract_tikz.tex - If ANY difference exists: update extract_tikz.tex from the Beamer source
- If extract_tikz.tex doesn't exist: create it from scratch
Step 1: Navigate to the lecture's Figures directory
cd Figures/$ARGUMENTS
Step 2: Compile the extract_tikz.tex file
TEXINPUTS=../../Preambles:$TEXINPUTS xelatex -interaction=nonstopmode extract_tikz.tex
Step 3: Count the number of pages
pdfinfo extract_tikz.pdf | grep "Pages:"
Step 4: Convert each page to SVG using 0-BASED INDEXING
CRITICAL: PDF pages are 1-indexed, but output SVG files are 0-indexed!
PAGES=$(pdfinfo extract_tikz.pdf | grep "Pages:" | awk '{print $2}')
for i in $(seq 1 $PAGES); do
idx=$(printf "%02d" $((i-1)))
pdf2svg extract_tikz.pdf tikz_exact_$idx.svg $i
done
Step 5: Sync to docs/ for deployment
cd ../..
./scripts/sync_to_docs.sh $ARGUMENTS
Step 6: Verify SVG files
- Read 2-3 SVG files to confirm they contain valid SVG markup
- Confirm file sizes are reasonable (not 0 bytes)
Step 7: Report results
Source of Truth Reminder
TikZ diagrams MUST be edited in the Beamer .tex file first, then copied verbatim to extract_tikz.tex. See .claude/rules/single-source-of-truth.md.
