Hi everyone I'm trying to change 'System.Drawing.Image' to 'System.Drawing.Image[] to use at my code so How To make it works as I need to merge tiff image to exist Multi Tif image thanks. and If I need to add pages to exist Multi tif image after select page how to do that? and if there another way to do that please help me?

    Image img2 = Image.FromFile(imagename1);
    Image img = Image.FromFile(imagename2);
    Tiff.TiffUtil.saveImageExistingMultiplePage(img2, img, 2, 
    imagename2);

CodePudding user response：

// initialize an image array and add your image to it
Image[] img2 = new Image[] { Image.FromFile(imagename1) };

// the rest of your code stays the same but 'img2' is now an array of images
// so the call to 'saveImageExistingMultiplePage' will accept it.
// ...

Tiff.TiffUtil.saveImageExistingMultiplePage(img2, img, 2, imagename2);

// ... continue your code
