Extract TikZ Diagrams to SVG

Steps

Step 0: Freshness Check (MANDATORY)

extract_tikz.tex

1. Find the Beamer source:

   ls Slides/$ARGUMENTS*.tex

2. Extract all

   \begin{tikzpicture}

   blocks from Beamer
3. Compare with

   Figures/$ARGUMENTS/extract_tikz.tex

4. If ANY difference exists: update extract_tikz.tex from the Beamer source
5. 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

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
