[Qgis-user] QGis server getprint request / layer order

[Neumann, Andreas]

Hi Lars, 

Regarding @xvfb: you don't need specifically xvfb, but any XServer. xvfb
is just one way of satisfying this requirement. Any XServer would do ...
It is a requirement of the qt library, if you want to output to PDF. 

------------------------ 

Regarding layer order: 

I had a similar issue - but it was the same layer order problem in
GetMap and GetPrint. I am surprised that the issue only surfaces in
GetPrint for you - are you sure? 

See the fix at
https://github.com/qgis/QGIS/commit/6b5a997df578a7996dc95e93690fe0a3d24e089b


So if you use QGIS server 2.18 which was compiled before April 18,
please install a newer version and see if the issue is fixed for you? 

Greetings, 

Andreas
