dxfToPng Error

[qing0]

Hello @mozman ,

I used examples\addons\drawing\draw_cad.py to convert a dxf file with a single line of text to png, but the following error occurred.

After debugging, the font was found to be the problem, which may be caused by the shx file I used. How can I solve this error
