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.

🔧 Installation

1️⃣ Install Dependencies

pip install -r requirements.txt

2️⃣ Install `wkhtmltoimage`

This project requires wkhtmltoimage, which is part of wkhtmltopdf. You need to install it manually.

🔗 Download wkhtmltopdf from:
👉 https://wkhtmltopdf.org/downloads.html

Make sure to add wkhtmltoimage.exe to your system PATH, or update the script with its full path.

📌 How It Works

This script:

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

📊 Input Fields

Field	Type	Description
`md_text`	String	Markdown text to be rendered into an image. Supports basic formatting (bold, italic, emojis).
`border_color`	String	HEX color or HTML named color for the image border (e.g., `#FFFF00` for yellow).
`border_size`	Int	Border thickness in pixels.
`image_width`	Int	Width of the generated image in pixels.
`image_height`	Int	Height of the generated image in pixels.
`background_color`	String	HEX color or html color name (e.g., `"lightblue"`).

🚀 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.
