# 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.**
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
```bash
cd Figures/$ARGUMENTS
```
### Step 2: Compile the extract_tikz.tex file
```bash
TEXINPUTS=../../Preambles:$TEXINPUTS xelatex -interaction=nonstopmode extract_tikz.tex
```
### Step 3: Count the number of pages
```bash
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!**
```bash
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
```bash
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`.
