I have a HDR 32 bit texture layer and now I want to read the color values.
For normal 8 bit textures this is not a problem, but how to get the 32 bit color values.
Here is my attempt:

	Float buffer[3];		//one pixel is 1 float (4 bytes) * 3 (RGB) = 3 floats
  
  
	//get one pixel to test
	pLayerBmp->GetPixelCnt(0,0,1,(UChar* )buffer,COLORMODE_RGBf, PIXELCNT_0);
  
	GePrint("Before pixel 0,0: " + String::FloatToString(buffer[0])  \+ " - " +
				String::FloatToString(buffer[1]) + " - " + 
				String::FloatToString(buffer[2]));

Solved.
Float buffer[3]; should be Float32 buffer[3];

In the C4D C++ SDK, defined 'generic' types usually default to the 64-bit version (Float = Float64, Vector = LVector, etc.).

Ok, good to know.
