Web Render Screenshot

Step 1: Create the HTML

Write a self-contained HTML file with inline CSS. Guidelines:

Step 2: Take the Screenshot

Use the bundled script:

python3 scripts/screenshot.py  [output.png] [options]

Or inline Python when the script cannot be invoked directly:

from playwright.sync_api import sync_playwright
with sync_playwright() as p:
    browser = p.chromium.launch()
    page = browser.new_page(
        viewport={"width": 1920, "height": 1080},
        device_scale_factor=4,  # 4x ultra-high res (default)
    )
    page.goto("file:///path/to/input.html", wait_until="networkidle")
    page.wait_for_timeout(1000)
    page.screenshot(path="output.png", full_page=True)
    browser.close()

Step 3: Deliver

Output MEDIA: for inline delivery, or use openclaw message send with --force-document for Telegram to avoid compression.
