    Re: how to save a shape as bmp file

    Hi madhu

    Try this code:

    If you want to save the image that is displayed in the picture box, complete with any lines that may have been drawn on top of it during run-time, you can use the Control.DrawToBitmap method

    Here's an example of a complete solution. First, the user is prompted by a save dialog (entitled "Save Image" and filtering to bitmap images (*.bmp) by default). If they click OK, the image displayed in the picture box is drawn to a temporary bitmap, and that temporary bitmap is saved to the location they specified. If they click Cancel, the file is not saved and the method simply exits.

    private void Save_Click(object sender, EventArgs e)
    {
        //Show a save dialog to allow the user to specify where to save the image file
        using (SaveFileDialog dlgSave = new SaveFileDialog())
        {
            dlgSave.Title = "Save Image";
            dlgSave.Filter = "Bitmap Images (*.bmp)|*.bmp|All Files (*.*)|*.*";
            if (dlgSave.ShowDialog(this) == DialogResult.OK)
            {
                //If user clicked OK, then save the image into the specified file
                using (Bitmap bmp = new Bitmap(pictureBox1.Width, pictureBox1.Height))
                {
                    picturebox1.DrawToBitmap(bmp, new Rectangle(0, 0, bmp.Width, bmp.Height));
                    bmp.Save(dlgSave.FileName);
                }
            }
        }
    }
