write_page_labels.json

The JSON file of the “Custom page labels” example. Pages numbered by their labels rather than their position.

JSON 186 lines

This file is a request: an application sends it over the network to the server, which creates the PDF and sends it back. It makes the same page as the Rust and Python versions of this example. A request names every file it uses, never its content; the call carries the request and the files together. A font the server already holds, such as DejaVuSans, is named with nothing attached. Send the request to the address the API page gives.

What this example is for

The number you type to go to a page ought to be the number printed on that page. In any document with a preface it is not: the reader asks for page 12, reading software counts pages from the front and shows them page 4. On a legal file or a technical manual, that is a reference nobody can follow.
