Problem Saving .Png Format RRS feed

  • User539648229 posted


    I create a Bitmap and when try to save it in png format there is an error. It says:

    Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

    Exception Details: System.Runtime.InteropServices.ExternalException: A generic error occurred in GDI+.

    There is no problem saving in gif or jpeg formats.

    and my code:

            // Create a new Bitmap object, 50 x 50 pixels in size
            Image canvas = new Bitmap(50, 50);
            // create an object that will do the drawing operations
            Graphics artist = Graphics.FromImage(canvas);
            // draw a few shapes on the canvas picture
            artist.FillEllipse(Brushes.Red, 3, 30, 30, 30);
            artist.DrawBezier(new Pen(Color.Blue, 3), 0, 0, 40, 15, 10, 35, 50, 50);
            // return the picture
            canvas.Save(Response.OutputStream, ImageFormat.Png);
            // now the drawing is done, we can discard the artist object
            // also the Bitmap
    Help please
