About This Workflow

This workflow automates the process of converting an image file (e.g., JPG) into a PDF document. It then demonstrates how to generate structured metadata for this document, ensuring it is available in both English (en) and Chinese (zh). The workflow uses the ConvertAPI service for the file conversion.

Key Features

Image to PDF conversion.
Generates structured metadata.
Supports both English and Chinese metadata.
Downloads an image from a URL.
Writes the converted PDF to disk.
Utilizes ConvertAPI for conversion.

How To Use

Trigger: The workflow starts by clicking the 'Test workflow' button.
Download Image: An example JPG image is downloaded from a URL (https://cdn.convertapi.com/public/files/demo.jpg) using the httpRequest node named 'Download Image'.
File Conversion: The downloaded image data is then sent to the 'File conversion to PDF' node. This httpRequest node uses the ConvertAPI v2 endpoint (https://v2.convertapi.com/convert/jpg/to/pdf) to convert the JPG to a PDF. It requires authentication via an HTTP Query Auth credential.
Write to Disk: The converted PDF file is saved to the local disk using the 'Write Result File to Disk' node, with the filename 'document.pdf'. The input data for this node comes from the data property of the previous node's output.
