<DIV><FONT face=Arial size=2>In everyone's opinion is it easier to drop a RGB

want a visual representation of the fft data [RGB and grayscale], because
I am not using it for calculations. I guess it depends on if there is any
useful information on the color channels. With regards to my application
[not the actual software but the project] I am not sure. There might be. I was
also thinking of creating a three display windows of the color channel
fft's. I would add this later. </FONT></DIV>

<DIV><FONT face=Arial size=2>Am I thinking of the fft's correctly? This is why I
