Does that implies we should set GC advanced to false as soon as possible after the advanced drawing (e.g. setAlpha)? Does it implies drawing after turning off GC Advanced is done via GDI and hardward accelerated?|
>> As soon you set GC#setAdvence(false), the advanced graphics subsystem is no longer used, advanced graphics state is cleared and the normal graphics subsystem "GDI" is used from now on, which is hardware accelerated.
I found this code in StyledText. Is it the recommended approach for every call to the advanced function like setAlpha, setAntialias?
>> Normally, the advanced graphics subsystem is invoked automatically when any one of the alpha, antialias, patterns, interpolation, paths, clipping or transformation operations in the receiver is requested.
>> When you don't need GDI+, it's better to turn Advance function 'off' as we do in StyledText.java
