NumSharp np.hstack(img1,img2,img3)

        var image1 = Cv2.ImRead(FirstImagePath).NotNull().ResizeToStandardSize();
        var image2 = Cv2.ImRead(SecondImagePath).NotNull().ResizeToStandardSize();
        var image3 = Cv2.ImRead(ThirdImagePath).NotNull().ResizeToStandardSize();
        var imageArray = np.hstack(image1.ToNDArray(), image2.ToNDArray(), image3.ToNDArray());
        var image = imageArray.ToMat();
        Cv2.ImShow(WindowName, image);
        FourthImageSource = image.ToBitmapSource();

print

• img1
• img2
• img3

python np.hstack(img1,img2,img3)

    img1 = cv.imread("./static/fllower.jpg")
    img2 = cv.imread("./static/lake.jpg")
    img3 = cv.imread("./static/mountain.jpg")
    img1 = cv.resize(img1, (200, 200))
    img2 = cv.resize(img2, (200, 200))
    img3 = cv.resize(img3, (200, 200))
    imgs = np.hstack([img1, img2, img3])
    cv.imshow("multi_pic", imgs)

print
img1 img2 img3

And,if i use code below,it print like python np.hstack

var imageArray = np.dstack(image1.ToNDArray(), image2.ToNDArray(), image3.ToNDArray());
