Usage

1. Open your Node-RED editor.
2. Drag and drop the pdf-to-png node from the palette to your workspace.
3. You can also pass the PDF path as the payload of the incoming message.
4. Connect the pdf-to-png node to other nodes as needed (e.g., an inject node to trigger the conversion and a debug node to see the output).
5. Deploy your flow.

Example Flow

Here is an example flow to demonstrate the usage of the pdf2png node:
