md-to-image

Convert Markdown tables to PNG images for chat interfaces that don't support table formatting (like Telegram).

When to use (trigger phrases)

Use this skill immediately when:

Any response contains a markdown table destined for Telegram or WhatsApp
User says "use table to image" or "convert this table"
Output has
```
| column | column |
```
pattern and channel is Telegram

Quick start

# Convert markdown file to PNG
node ~/.openclaw/workspace/md-to-image/md-to-image.js input.md output.png --scale=2

# Convert from stdin
echo "| A | B |\n|---|---|" | node md-to-image.js - output.png

Auto-apply

This skill auto-applies at 95% confidence when:

Channel is Telegram or WhatsApp
Content contains
```
| table |
```
pattern
2+ rows, 2+ columns
Data is informational (not ASCII art)

Options

Option	Default	Description
`--scale`	2	Image scale (2x for retina)
`--theme`	calm	Color theme: calm, dark, colorful
`--width`	auto	Table width in pixels
