Detect if PDF is colored [DATALOGICS][APDFL]

I am using APDFL 10.1.0 to convert PDF to images. This is how I am loading the PDF file and saving a specific page as image:

Document pdfdocument = null;
pdfdocument = new Document(docpath);
Page docpage = pdfdocument.GetPage(pagelist[0]);
Image pageimage = docpage.GetImage(PageRect);

Is there a way to detect from either the docpage variable or the pageimage variable if the specific page is colored or is grayscale?

You can use pageImage.NumberComponents to determine this. Color Images will have 3 or 4 components (depending on whether it is an RGB Image or a CMYK Image) while grayscale Images will have 1 component.
