Global Mapper v26.0

Color Histogram of a Raster layer

Hi,

I am trying to match histograms between two or more raster layers using the SDK functions. I would like to know if there is a method or function that helps me get the color histogram of a Raster layer or other color information that can help me with histogram matching. I see that for v18.1 one of the new features is "function to calculate color statistics within an area" but I have not found such function in the API documentation. I am working with C++, SDK 20.0

Thanks
