PDF 1.5 Standard Compliant example using RBGroups
SUMMARY
When using RBGroups (RadioButton groups) of Optional Contents, we can switch
from one group to another one in the "layers" panel of okular, but the drawing
of the corresponding graphic objects is not updated.
STEPS TO REPRODUCE
1. open the attached file "Labels_and_Languages_3_OC.pdf"
2. open the "layers" panel
3. open the "Language" group
4. switch from one language to another
OBSERVED RESULT
The switching between languages in the user interface is correct (mutually
exclusive Optional Contents is implemented via the RadioButton group) but the
display is not updated: texts are overwritten on the display.
EXPECTED RESULT
Each language should lead to different text strings.
SOFTWARE/OS VERSIONS
Linux distro: Ubuntu-19.04 (and before)
Okular version: 1.6.3
PDF Backend: 0.6.5
KDE Framework: 5.56.0
Qt version: 5.12.2
ADDITIONAL INFORMATION
The PDF has been generated by my own graphic library Muesli. You can open the
attached PDF file with any text editor since it uses only ASCII characters. To
my knowledge, it is standard compliant: 'mupdf' doesn't claim about any errors,
and the "PDF Tools Online" validator
(https://www.pdf-online.com/osa/validate.aspx) returns nothing special about
it:
Validating file "Labels_and_Languages_3_OC.pdf" for conformance level
pdf1.5
The document does conform to the PDF 1.5 standard.
Done.
