Generics does not respect "monochrome reverse"

It seems to me that the generics type shown in class does not work with "monochrome reverse":

  skinparam monochrome reverse
  skinparam backgroundcolor transparent
  hide circle
  class Collection<T>
  void addItem(T item)
  boolean hasNext()
  T getNext()
  void resetNext()
  boolean isEmpty()

Hello J.,


[See on PlantUML server]

A possible workaround is to use style for the background:

document {
  backgroundcolor transparent

Then the expected result is observed:

If that can help,

Hi there.

I run with what comes in Fedora 32, plantuml version 1.2019.01 , and even with

skinparam useBetaStyle true

CSS styles do not seem to be working. Documentation of useBetaStyle indirectly refers to version 1.2019.9, so perhaps the feature was introduced then.

Still, thanks.

Hello all,

In fact the main issue in on 'backgroundcolor transparent'; because with 'monochrome reverse' the background is not really transparent, but white [the reverse of #00000000 is #ffffffff !wink].

Then a possible workaround, is to put a grey color on background, as:

skinparam backgroundcolor DimGrey

Then a possible expected result is observed, without to have got all in black:

Contrary to without any background:

Thanks for the report.

We've made some changes in last beta and on the online server.
