Edgar,

Thank YOU so much!!!!

One question...

In the following code :

public static class NativeMethods {
	[DllImport("lcms2.dll")]
	public static extern void cmsDoTransform(
		[In] IntPtr Transform,
		[In] byte[] InputBuffer,
		[Out] byte[] OutputBuffer,
		[In] UInt32 Size);
}

Why (warum) do you pass a pointer to a byte array (byte[])?

(I understand image pixel data = bytes)

I am no C# specialist BUT that makes the function "less universal" than if
you were to pass a straight, basic 'IntPtr'?

The reason I ask is, are you not limited to the type of data you can pass
cmsDoTransform then?

In my original pinvoke declaration, I use pointers to 'double[]' arrays :
this will not work (arbeit) with your 'byte[]' declaration anymore?

I was thinking of, perhaps, the solution is create a second class to host
your cmsDoTransform function call and continue using my first cmsDoTransform
to process individual 'double[]' data type.

Is that what you do?

MfG / Kindest regards,
