In case you don't know, we can resize image inside Blender.

I have searched this topic before on stack exchange and the forum etc. Didn’t find anything useful.

But after I read the API, I can’t believe how easy it actually is.


bpy.data.images["__ImageName__"].scale(pixel_size_x, pixel_size_y)

in the console. Antialiasing is automatically applied when doing so.
