Render Compare

Render HTML through the EggPdf pipeline and analyze the PDF content stream for rendering issues.

/render-compare <html or template-name>

If argument is a template name (invoice, report, letter, etc.), use that template. If argument is HTML, render it directly.

Ensure service is running

curl -s http://localhost:55727/health || (dotnet run --project src/EggPdf.Service -c Release -- --urls http://localhost:55727 & sleep 8)

Render the HTML via the API:

curl -s -X POST http://localhost:55727/api/render \
  -H "Content-Type: application/json" \
  -d '{"html":"THE_HTML"}' -o /tmp/render_compare.pdf

Extract and analyze the content stream:

cat /tmp/render_compare.pdf | sed -n '/^stream$/,/^endstream$/p'

Verify paint order (CRITICAL):
- For each element with a background, the fill operation (re f or h f) MUST appear BEFORE the text (Tj)
- If text appears before its background, it will be invisible (painted under the background)
Verify all text is present:
- Extract all Tj operations and check that expected text strings are in the PDF
- Check for ? characters replacing special chars
Verify layout:
- Check X/Y coordinates of text match expected positions
- Check that no content extends beyond page boundaries (MediaBox)
- Check flex item positioning (items should be side-by-side, not stacked)
