Images are rotated in PictureBox

Question

As the question implies, when I load an image into a pictureBox (using dialog box), it doesn\'t appear as its original look. in this screen shoot, the image on the left is t

Answer 1

When you view an image in Windows Photo Viewer, it automatically corrects image orientation if it has an Exif orientation data. PictureBox doesn't have built-in support for such functionality. You can create a custom PictureBox which shows images correctly even if they have orientation data:

using System.Linq;
using System.Windows.Forms;
using System.Drawing;
using System.ComponentModel;

public class MyPictureBox : PictureBox
{
    private void CorrectExifOrientation(Image image)
    {
        if (image == null) return;
        int orientationId = 0x0112;
        if (image.PropertyIdList.Contains(orientationId))
        {
            var orientation = (int)image.GetPropertyItem(orientationId).Value[0];
            var rotateFlip = RotateFlipType.RotateNoneFlipNone;
            switch (orientation)
            {
                case 1: rotateFlip = RotateFlipType.RotateNoneFlipNone; break;
                case 2: rotateFlip = RotateFlipType.RotateNoneFlipX; break;
                case 3: rotateFlip = RotateFlipType.Rotate180FlipNone; break;
                case 4: rotateFlip = RotateFlipType.Rotate180FlipX; break;
                case 5: rotateFlip = RotateFlipType.Rotate90FlipX; break;
                case 6: rotateFlip = RotateFlipType.Rotate90FlipNone; break;
                case 7: rotateFlip = RotateFlipType.Rotate270FlipX; break;
                case 8: rotateFlip = RotateFlipType.Rotate270FlipNone; break;
                default: rotateFlip = RotateFlipType.RotateNoneFlipNone; break;
            }
            if (rotateFlip != RotateFlipType.RotateNoneFlipNone)
            {
                image.RotateFlip(rotateFlip);
                image.RemovePropertyItem(orientationId);
            }
        }
    }
    [Localizable(true)]
    [Bindable(true)]
    public new Image Image
    {
        get { return base.Image; }
        set { base.Image = value; CorrectExifOrientation(value); }
    }
}
