Hi everyone
thanks Constantin for your reply
I'm sorry if this is repeated,i don't know if it was sent the first time
Is Fast pixel drawing still not supported in MacOS and other platforms even using
recent JVMs?
I could not find anything about Graphics.drawImage(...) support at java.sun.com
I assume this means it is supported for all JVMs ??
also if anyone has any information about how TightVNC Java Applet draws images it will
be great
to hear them

"Raw pixel drawing" = "Fast":
The drawing is performed using a Graphics.drawImage(...) method,
where the image source is a MemoryImageSource object.
This method does not work everywhere, e.g. it was reported not
working under MacOS / MRJ browsers.
"Raw pixel drawing" = "Reliable":
The drawing is performed using Graphics.setColor(...) and
Graphics.fillRect(...) for _each_ pixel of the raw data block.
This method can be _much_ slower but usually works under different
JVMs.
TightVNC 1.2.3 Java viewer does not use this option, its drawing model
is very different and was aimed to be both fast and reliable.
