How to resize an image.

C#

Sometimes we want to save an image of a given dimension.
Below method 'resizeImage' is to resizing the image 'imgToResize' for a given size 'size'

private static Image resizeImage(Image imgToResize, Size size)
{


int destWidth = size.Width;
int destHeight = size.Height ;

Bitmap b = new Bitmap(destWidth, destHeight);
Graphics g = Graphics.FromImage((Image)b);
g.InterpolationMode = InterpolationMode.HighQualityBicubic;

g.DrawImage(imgToResize, 0, 0, destWidth, destHeight);
g.Dispose();

return (Image)b;
}


The above method can be utilized as -

Image imgOriginal = new Image.FromFile(imgFilePath);
Image imgResized = this.resizeImage(imgOriginal , new Size(100,100));

imgResized.Save(SaveToFilepath);

Now for any size of original image we will get an image of size 100 * 100.
