    You can refer to Microsoft Github Sample:print-oem-samples which Adds Texts and Images To Visual Collection.
    The Following is AddImageToVisualCollection:

     /*  PrintWorkflowXpsReceiver::AddImageToVisualCollection
        *
        *  If the source image is available in the XPS OM as an image resource, 
        *  it can be used to create an image brush object and added as the fill brush to the path
        *  that describes the image location and size in the page.
        *
        *  Arguments:
        *      _In_ ComPtr<IXpsOMPage>  &xpsOMPage            XPS Page Object Model
        *      _In_ IXpsOMImageResource *imageResource        Image resource to add to the page
        *      _In_ XPS_SIZE            *imageWidthAndHeight  Pixel width and height of image
        *      _In_ FLOAT                dotsPerInchX         Image X resolution in dots per inch    
        *      _In_ FLOAT                dotsPerInchY         Image XY resolution in dots per inch  
        *      _In_ XPS_RECT             rect                 Image size and location
        *      _In_ LPCWSTR              shortDescription     Short text description of image
        *
        *  Returns:
        *       E_INVALIDARG      Invalid imageResource
        *       S_OK              Success
        *       Other             HRESULT of error
