[QGIS-Developer] Using QgsProfilePlotRenderer in processing algorithm

[simon at sgroe.at]

Hi all,

I have created a simple python script that generates and renders a 
series of profile plots. It works fine. Now I would like to transform 
the script into a processing algorithm in order to create a better UX 
and to allow users to set some parameters (e.g. plot distance in 
exported image).

Unfortunately, the generation process (in the background thread) never 
finishes within the processing algorithm. It works fine in the simple 
python script (without processing algorithm).

You can find the code here:

Is there an issue with the background threads (algorithm thread vs. plot 
generation thread)?

Best regards
Simon
