PDF exporting results in recursively generated files

[nql5161]

Intro

Hi, I appreciate the effort you have put into this tool and it's extremely valuable to the effort it's apart of. It saves costly developer time that can be preciously used elsewhere.

I started using this tool for generating SVGs that are shown in an Azure DevOps wiki. It works great for this usage, although I'm afraid it wasn't exactly what I had in mind.

Issue

When trying to generate PDFs, it recursively generates the PDFs like a reverse Fibonacci. What I mean by this is when running docker run -it -v $(pwd):/data rlespinasse/drawio-export, it results in PDF files being made for each page in the diagram but the first PDF will contain all of the diagrams from the Draw.IO instead of just the contents of the first page.

Let's say page 1 is titled "FirstPage", page 2 is titled "SecondPage", so on and so forth. After generation is complete, the output file FirstPage.pdf will contain pages 1 through N instead of only containing the content from "FirstPage". The output file SecondPage.pdf will contain pages 2 through N, excluding the page that proceeded it in the Draw.IO file.

Questions

• How do I generate a PDF document per page in the Draw.IO diagram without containing other pages?
• Is it possible to generate a PDF document that contains a page for each diagram in the Draw.IO instead of separate PDF documents?

@nql5161 thanks for this issue.

Your first question seems to be a bug, I will look into it.
For the second one, will need a new feature to be possible, see rlespinasse/drawio-exporter#17.

I reproduce the reverse Fibonacci bug with the PDF type. After some search, the issue was reported on jgraph/drawio#3597.
This docker image needs to be based on a drawio-desktop version greater than 21.3.3.

Base image updated with latest drawio-desktop version rlespinasse/docker-drawio-desktop-headless#37
