How to crop an image using C#?

Question

How can I write an application that will crop images in C#?

Answer 1

This is another way. In my case I have:

• 2 numeric updown controls (called LeftMargin and TopMargin)
• 1 Picture box (pictureBox1)
• 1 button that I called generate
• 1 image on C:\imagenes\myImage.gif

Inside the button I have this code:

Image myImage = Image.FromFile(@"C:\imagenes\myImage.gif");
Bitmap croppedBitmap = new Bitmap(myImage);
croppedBitmap = croppedBitmap.Clone(
            new Rectangle(
                (int)LeftMargin.Value, (int)TopMargin.Value,
                myImage.Width - (int)LeftMargin.Value,
                myImage.Height - (int)TopMargin.Value),
            System.Drawing.Imaging.PixelFormat.DontCare);
pictureBox1.Image = croppedBitmap;

I tried it in Visual studio 2012 using C#. I found this solution from this page
