Investigations on using ResInsight to render plots in a compleatly Headless state
- Qt 5.8 or higher needed, it seems. Tested with Qt 5.14.1. Tested with Qt 5.6.1 on CentOS 6 and the plots was rendered without fonts.
- Start ResInsight with the additional options -platform offscreen
- The project can not contain visible 3D views. If it does, ResInsight will crash
- Might add -stylesheet <path to stylesheet definition file> to explicitly control fonts
example contents of stylesheets file:
* { font: bold italic large "Times New Roman" }
The "*" might be substituted with specific classes or widgets.
It seems as the Qwt plot axis-titles are not affected by the stylesheet set above
- Example command line:
./ResInsight --project FPPLot.rsp --savesnapshots all --snapshotsize 500 500 -stylesheet stylesheet.txt -platform offscreen
