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).

At present, it looks like thisProcessing modeller

Since I wish to export it, I want it to visually look like the following example sourced online. Graphical modeller e.g.

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)?

    As far as I know, resizing the boxes in the modeller is not possible. You could you an external flowchart building program, or abbreviate your descriptions. – Erik Jan 22 '18 at 8:23
  • Can you edit the question title? Exporting as a PNG is not your problem, there's a button for that, a better title would be "How to stop truncation of descriptions in qgis-modeler" – Spacedman Jan 22 '18 at 8:35

    I've just written a short python function that can export the modeler scene as an SVG file, which you can then load into Inkscape (or any other SVG) editor and tweak the appearance however - change fonts, put gradients on the boxes... Needs integrating into the modeler plugin though... – Spacedman Jan 23 '18 at 21:51
  • And just heard that QGIS3 has "Export to SVG" in the modeler anyway! – Spacedman Jan 23 '18 at 23:40
