Star Office Gallery *.sdg not shown

[jenderek]

some days ago i handle some Star Office Galleries with file name
extension sdg. When i try to open such files with XnView no graphics
are displayed.

The used XnView Classic version was 2.49.1 running on Windows
operating system.

According to feature page https://www.xnview.com/en/xnview/#formats
on XnView web site Star Office Gallery with file name extension sdg
should be supported.

I also look for other versions of sdg files. The same gallery format
seems to be used in old StarOffice 5.2 dated about May 2000. And the
format seems to be still used in actual LibreOffice with version
6.3.2.2 and also in OpenOffice 4.1.6. But no of the found sdg files
can be displayed by XnView.

So maybe somebody can check what is going wrong here.

Thanks for tips and advice.
