So if the view scale is up close - there is no problems: all lines looks relatively smooth. But if I zoom to fit all A4 sheet - most of the text looks ugly. As I suppose this is due to the fact that schematic editor do not uses anti-aliasing.
Is there any possibility to turn it on?
Most of the Internet search gives results regarding 3D view which is I believe not my case.
the rendering engine that is drawing the Schematics is from the beginnings of KiCAD…
it has no option for anti-aliasing.
for this you have to wait until Eeschema is ported to use the the new GAL rendering
(currently Cairo and OpenGL as they are in PCBnew)
on the [CERN KiCad development roadmap wiki][1] you can follow the progress in some way…
