- Parameters:
g
- The Graphics2D object in which to paint
-
getAlpha
public float getAlpha()
Returns the current alpha value for this painter. This is the alpha value that will be applied to all painters set inside this painter. Alpha values will be multiplied. This means if you set an alpha of 0.5 on this painter and you nest a painter inside which uses an alpha of 0.5 then the final pixels drawn will have an alpha of 0.25.- Returns:
- the current value of alpha property
-
setAlpha
public void setAlpha(float alpha)
Sets the current alpha value for this painter. This is the alpha value that will be applied to all painters set inside this painter. Alpha values will be multiplied. This means if you set an alpha of 0.5 on this painter and you nest a painter inside which uses an alpha of 0.5 then the final pixels drawn will have an alpha of 0.25.- Parameters:
alpha
- the new value of the alpha property
