[QGIS-Developer] RV: PyQGIS QgsLayoutExporter gives error "QPen::setWidthF: Setting a pen width that is out of range"

[rbenet71 at gmail.com]

Hi Nyall,
 
                Thank you so much for your answer.
 
                    I put in yellow myAtlas.beginRender()
                 myAtlas.next()
 
                In my app there are more code obviously, but not affect, to generate the picture/PDF.
 
                For mi the problem is inside this order:
exporter.exportToPdf(file_name,pdf_settings)
 
                Something inside this order give the error.
 
                If I generate the picture with Qgis desktop program all works perfect, but if I do with “exporter.exportToPdf(file_name,pdf_settings)” then some elements not appear.
 
                Here you have and example.
 
                General Map have a lot of elements, I write a box where I make zoom.

                In Zoon_Map, you can see elements. Some of this elements not appear if I create the map with my code.
 

                I write a circle around and element.
 
                Thank you so much for your attention in advance.
 
Kind regards,

Thank you In advance for your attention and help.
 
Have you stripped code out of this loop? Eg I can't see any call to atlas.next() within the loop.
 
In any case what you have looks generally ok. You'd need to share more of your code or project to diagnose further.
