CreateMarkdownImage ComfyUI node

This project generates an image from Markdown text using imgkit and wkhtmltoimage. It automatically scales the text to fit within the specified image dimensions.

📌 How It Works

This script:

1. Converts Markdown text into HTML.
2. Renders the HTML into an image using imgkit.
3. Dynamically adjusts the font size to maximize readability.
4. Returns the image as a PyTorch tensor.

🚀 Usage

from create_markdown_image import CreateMarkdownImage

generator = CreateMarkdownImage()
image_tensor = generator.createmarkdownimage(
    md_text="**Hello World!** 🚀",
    border_color="#000000",
    border_size=2,
    image_width=800,
    image_height=200,
    background_color="white"
)

This will generate an image containing "Hello World! 🚀" with a black border and a white background.

🛠️ Troubleshooting

• If imgkit fails, ensure wkhtmltoimage.exe is installed and accessible.
• If text doesn't scale correctly, adjust the image_width and image_height fields.
