I want to increase the quality of the image output.

Question

Hello.
I am creating a class diagram in PlatUML and exporting it as PNG, but the quality is too low to see the details.
Is there any way to increase the output quality of this image?
I tried to check it myself, but could not find anything except PLANTUML_LIMIT_SIZE.
I thought about outputting it as SVG, but I want to output it as PNG this time.

Thank you very much for your help.

Would changing to SVG be an option?

We believe that changing the SVG will not change the resolution.
However, I have described what I have tried.

Sorry, I missed the SVG part, though I think it might be good to reconsider the usage of PNG over SVG.
