setup

public void setup(FontContext fontContext)

Specified by:

setup in interface TextRenderer

setFontScale

public void setFontScale(float scale)

Specified by:

setFontScale in interface TextRenderer

setSmoothingThreshold

public void setSmoothingThreshold(float fontsize)

Description copied from interface: TextRenderer

Set the smoothing threshold. This is a font size above which all text will be anti-aliased. Text below this size will not be anti-aliased. Set to -1 for no antialiasing. Set to 0 for all antialiasing. Else, set to the threshold font size. does not take font scaling into account.

Specified by:

setSmoothingThreshold in interface TextRenderer
