In VS Code, how to set the paper size to export full diagram?

Question

Hello,

I'm using PlantUML to model one book content structure, the level 1 and level 2 are OK for both preview and output (to PNG), but when come to level 3, since it's very wide in the horizontal side, although I can preview in VS Code, but when export, it's trimmed in the horizontal.

Are there any settings that can make the export PNG image paper size wider?

I put the preview and output image files in below Github link, hope you can check and give help:

The preview is here:

The actual output PNG is here:

Thanks, Xiaoqi
