[QGIS-Developer] Reading current measurement with python

[Jacky Volpes]

Hi,

If I understand well, it's possible that a styled layer could be 
sufficient...?
See "Description" section on this style 
<https://plugins.qgis.org/styles/5/>.
Import the style 
<https://docs.qgis.org/3.28/en/docs/user_manual/style_library/style_manager.html#importing-items> 
in QGIS style manager.

Regards,

Jacky Volpes
