Hello!
I can increase line width as I want, but if I try to set it below 1, it does not decrease? Is there anyway to force it to decrease.
Kind regards
Nope, that is not supported.
Out of curiosity, is there a reason one cannot scale it “indefinitely”? Perhaps the rendering pipe line?
Kind regards
My guess is that OpenGL doesn’t support line widths less than 1 pixel. The docs say:
GL_INVALID_VALUE is generated if width is less than or equal to 0.
It also says, without antialiasing:
If the rounding results in the value 0, it is as if the line width were 1.

To go smaller than width 1, we would need ParaView to enable multisample anti-aliasing, which we don’t do I think for performance reasons.
