GSPS is not rendered correctly in 3.7.0

[Ch00k]

Describe the bug
The GSPS is only partially rendered in Weasis 3.7.0.
The GSPS contains objects of different colors: white and blue. The white part shows fine, but the blue one does not. In Weasis 3.6.2 the entire GSPS is displayed correctly.

To Reproduce
Steps to reproduce the behavior:

1. Download weasis_gsps.zip, unpack and open the two DICOM files in Weasis.
2. Select AIDENCE VEYE in GSPS dropdown menu.

Expected behavior
Both the white and the blue parts of the GSPS are displayed correctly.

Desktop (please complete the following information):

• OS: macOS 11.2.1
• Java Rutime: Java version = 16
• Weasis Version 3.7.0, 3.7.1 (unreleased)

Additional context
This could be related to #181, however I also tried the 3.7.1 version that fixed the problem in #181, but it does not fix this problem.

Yes, the new version supports Pattern On Opacity Attribute and in your case the opacity value is 0.0 => transparent

@nroduit sorry, I'm not sure I understand what you mean exactly. You mean it's a feature, not a bug? Should I fix my GSPS instead to make the blue text non-transparent?

[nroduit]

Yes, I was wondering if it would be safer not to allow the value 0.0 but at the same time it is a valid value.

I changed the PatternOnOpacity to 1.0 which made Weasis render the GSPS correctly. I guess this issue can be closed now. Thanks a lot for looking at it!
