Hello,
Thanks for the info. I was getting rather confused on how to take advantage of hardware and somehow got it in my mind that by default all rendering would be in software. The archived posts I read kept talking about that createCompatibleImage method. So I should be okay by just using the toolkit?
following is the code I am using and still cannot draw to the buffered image can anyone see what I am doing wrong? (Although I don't really need to do it anyway)
