I created this converter mbx2svg for MindBoard / MindBoard 2019.
Currently stop subscription entry for MindBoard and MindBoard 2019 as temporary. Unless subscription users, it's impossible export your MindBoard data to PDF. I expect this tool help this issue.
Before conveting your mindboard data, in order to build mbx2svg executable binary. It's required JVM 17.
I tested at this env:
$ java -version
openjdk version "17.0.9" 2023-10-17
OpenJDK Runtime Environment (build 17.0.9+9-Ubuntu-122.04)
OpenJDK 64-Bit Server VM (build 17.0.9+9-Ubuntu-122.04, mixed mode, sharing)
Step 1:
$ git cloen https://github.com/mindboard/mbx2svg.git
Step 2:
$ cd mbx2svg
Step 3:
$ ./gradlew bootJar
Building has finished, you can get the executable jar binary in the build/libs/mbx2svg-0.1.jar.
Step 4:
Let's convert the example file. There is a demo mbx file in the Demo/example.mbx.
$ java -jar build/libs/mbx2svg-0.1.jar Demo/example.mbx -o example.svg
A result SVG file is an example.svg .

This tool can be handle files that was exported (to Google Drive and download them in your local pc) from MindBoard / MindBoard 2019 apps.
That's all.
