Hi,
I am trying to save an image with LayoutView.save_image()
But merely creating a new LayoutView object results in a segmentation fault (ERROR: Signal number: 11
).
I use Klayout 0.25.9 (installed with the deb
file from https://www.klayout.de/build.html) in a fully updated Ubuntu 18.04 LTS VM to call the Python script in interpreter mode:
klayout -z -nc -r /path/to/test_layoutview.py
test_layoutview.py
:
import pya
#Test if calling LayoutView() works
lv = pya.LayoutView() #This causes the seg fault
I have uploaded the full error message and the log of valgrind from running valgrind klayout -z -nc -r /path/to/test_layoutview.py .. >valgrind.log 2>&1
to Github.
Issue #289 is on Github already, but I thought discussing it in the forum as well might be a good idea.
It may of course be an error on my part. If so, I would be thankful for advice on saving a PNG image with a Python script other than:
import pya
layout = pya.Layout()
layout.read('filename.gds')
lv = pya.LayoutView()
lv.create_layout(lv, True)
lv.save_image('filename.png', 500, 500)
Any help would be highly appreciated :-)

Hi,
I see that a segfault isn't really a nice way of saying "don't do it this way".
The right way is do let the main window create a view
A view can be a Widget embedded into other widgets, but it has a parent in this case. I guess the segfault is because there is no such parent.

Thank you so much!
That worked
