Question

What i want to is, take 3 images, that the 1st image, keep it to original size concatenate anothother image to the bottom of it only using 1/2 of the first images size( starting on the left side). Then take the 3rd image and put it on the bottom right half of the first image I've looked for example all day, does anybody have an idea or an idea?

Answer 1

If you ignore aspect ratio:

        Image img1;
        Image img2;
        Image img3;

        Bitmap display = new Bitmap(img1.Width, (int)(img1.Height * 1.5));
        Graphics g = Graphics.FromImage(display);

        //draw img1 to upper left corner
        g.DrawImage(img1, 0, 0);

        //draw img2 under img1, left side
        g.DrawImage(img2, 0, img1.Height, img1.Width / 2.0f, img1.Height / 2.0f);

        //draw img3 under img1, right side
        g.DrawImage(img3, img1.Width / 2.0f, img1.Height, img1.Width / 2.0f, img1.Height / 2.0f);

Answer 2

也许我没有正确理解这个问题，但似乎您可以创建一个新的Bitmap并在正确的坐标处将 3 个图像绘制到其中，您应该能够从单个图像尺寸中找出（我相信） Bitmap对象为您提供）
