A horizon is shown on OSD by default. I want to show black lines I drawed by hand on OSD, how to enable it? I don’t know what is the standard name of these black lines.
I think one term for it is a “pitch ladder”.
I think you will need to find an OSD font that has that. The 4 selections available do not as far as I know.
From github I now know that this feature requires some graphics hardware.
