I just started to use gdsCAD and followed the examples proposed in the user’s guide page. I created an example gds file and I displayed the layout object with the “layout.show()” command: the viewer opened, blocking the python console, which remained blocked also after quitting the viewer.
The trick to solve this issue is simple: the “show”method uses the matplotlib.pyplot “show()” method without input parameters.
import matplotlib.pyplot as plt
import …
…
…
def _show(self):
…
…
…
plt.show()
…
…
It’s enough to change the source code, adding the parameter block=False in the line where the matplotlib.pyplot show() method is called:
plt.show(block=False)
and the viewer does not block the python console any more.
