Line thickness in Drawing-API

[1081]

Version: 1.6.2 (and below)

dearpygui.draw_line(thickness= expects a float, but the line thickness only changes (noticeably) in integer steps. I am not able to draw a line with 0.5 thickness.

Unfortunately, the difference between thickness 1 and 2 is quite large. In my application, I can effectively only use line thickness 1.

Example thickness = 1:

Example thickness = 2:

Is it possible to make the different in line sizes (especially 0.5) more distinctive/identifiable?

Looking at different screen resolutions, I realize that this is not an easy task. Most likely, this is just the way ImGui renders lines. But maybe there is some way to adjust the render settings?

Zoom: 0.25 and 1.25 are slightly different (when I squeeze my eyes) but 0.5, 1.0 and 1.25 are the same.
