Subject: TDibGraphic->RGB problems

I'm having a quick play with the Eval to see if it suits my needs and I'm having some problems with TDibGraphic->RGB function. I'm using BCB 5.

I have a TDibGraphic that has loaded an image (which I can display in TImageScrollList). When I try:
MyTRgb = MyDib->RGB(x,y);

I get told "Wrong number of arguments in call of macro 'RGB'."

When I try:
MyTRgb = MyDib->RGB[x,y];

I get told "Too few parameters in call to '_fastcall TDibGraphic::GetRGB(const int,const int)'"

As far as I can see in the documentation the only required parameters are an x and y coordinate. What am I doing wrong?

Also I noticed that I can use Bits to get the info I want as well. What is the format of the PByteArray if the ImageFormat is truecolor? Thanks for your help.
