skinparam Dpi causes exception #343

Closed patrickp-at-work closed 2 years ago

patrickp-at-work commented 2 years ago

How to reproduce

@startuml
skinparam Dpi 100

try to change 100 to 200 by first deleting the 1 and then typing the 2.

Observed outcome

After deletion of the 1, an org.apache.batik.transcoder.TranscoderException is thrown. IntelliJ reports this as a plugin error ("IDE Fatal Errors: Exception in plugin...)".

Stack trace

org.apache.batik.transcoder.TranscoderException: null Enclosed Exception:

It seems to me that it is more a Plantuml bug, it should not generate such things
