Draw a line between points in the sky.
- Parameters
-
a the first point b the second point

int | height ) |
Definition at line 142 of file skyqpainter.cpp.
◆ setVectorStars()
|
inline |
- Parameters
-
vectorStars Draw stars as vector graphics whenever possible.
- Note
- Drawing stars as vectors is slower, but is better when saving .svg files. Set to true only when you are drawing on a canvas where speed doesn't matter. Definitely not when drawing on the SkyMap.
