Saving image to file

Question

I am working on a basic drawing application. I want the user to be able to save the contents of the image.

I thought I should use

System.Drawing.Drawing2D.GraphicsState img = drawRegion.CreateGraphics().Save();

but this does not help me for saving to file.

Answer 1

You could try to save the image using this approach

SaveFileDialog dialog=new SaveFileDialog();
if (dialog.ShowDialog()==DialogResult.OK)
{
   int width = Convert.ToInt32(drawImage.Width); 
   int height = Convert.ToInt32(drawImage.Height); 
   using(Bitmap bmp = new Bitmap(width, height))
   {
       drawImage.DrawToBitmap(bmp, new Rectangle(0, 0, width, height));
       bmp.Save(dialog.FileName, ImageFormat.Jpeg);
   }
}
