I am trying to make a QGIS processing workflow through the Graphical Modeler (QGIS 2.18.15). I have completed it, and wish to export it as a *.PNG. However, the elements and algorithms I added to the modeller are visually incomplete (unable to see the whole text written per element).
How do I customize it such that my text per element is not truncated? And, is it possible to customize the aesthetics of the QGIS graphical modeller (within our outside of QGIS)?
