PDF4meInstall

Summary

Extracts PDF metadata through the PDF4me service and returns it as a JSON file in binary output.

Inputs

• Input Data Type (required) — Selects the PDF source: a binary field from a previous node, base64 PDF content, or a PDF URL.
• Input Binary Field (required) — Binary property containing the PDF; shown when the source is Binary Data. Defaults to data.
• Base64 PDF Content (required) — Base64-encoded PDF; shown when the source is Base64 String.
• PDF URL (required) — URL of the PDF to process; shown when the source is URL.
• Output File Name — Name for the metadata file; defaults to pdf_metadata.json.
• Binary Data Output Name — Name of the output binary property; defaults to data.
• Async — Whether to enable asynchronous processing; defaults to true.

Output shape

A single item containing the extracted metadata as a JSON binary file.

The JSON file is placed in the binary property named by Binary Data Output Name. The supplied properties are displayed for Get PDF Metadata, although the requested operation is labeled Get PDF Information; the provided source pack does not expose the operation implementation, so runtime behavior and output shape cannot be confirmed from source.

Examples

Example 1: Get metadata from an upstream PDF file

Select Binary Data, set Input Binary Field to the incoming binary property (default data), and optionally set the output file name and binary property name.

Example 2: Get metadata from base64 PDF content

Select Base64 String, provide the encoded PDF, and configure the output file name and binary property name if needed.

Example 3: Get metadata from a PDF URL

Select URL and provide the PDF URL; configure the output file name and binary property name if needed.
