Can't scale image plane

[skoczo]

Hi. I'm trying to use image as template. I successfully imported image but can't scale it. When i choose image scaling option i'm getting following exception

Code: Select all

Running the Python command 'Image_Scaling' failed:

I'm using manjaro and free cad from manjaro repo but i also built freecad from git and i have the same error.
This is info from my git build

Works perfect here. Perhaps an issue with the image?

Should it be some specific image format?

I tested with a jpeg.

I installed pyenv and set python 3.9.9 as default. Now in bash i have python in version 3.9.9 but in freecad there is still version 3.10.1. How to change that?

I tried to build it with 3.9.9 but it looks like 3.10 is minimum

Code: Select all

cmake ../FreeCAD/ -DPYTHON_EXECUTABLE=/home/skoczo/.pyenv/shims/python3.9

Code: Select all

Which version of python do you have?

So it looks like my problem might be with wrong python version. Now i need to find out how to force freecad to use 3.9.9 instead of 3.10.1
