In linux we are using osgEarth::Annotation::PlaceNode to display some chinese characters.Then
we find the Text looks a little blur when the size of characters is small.
Or,the Black characters seems a little gray when the character size is small。I can barely see the strokes of the Chinese character. I have setFontSolution(128,128),it dose not help.
Then I find our old app which using QT to draw text,and with the same font,QT text looks better than the PlaceNode. It seems Qt rendering to a 2D window where font resolutions can
exactly matched to the pixels on screen
So my question is there any way to make the text looks better when the character size is small?
