A generic error occurred in GDI+.

[klharding]

I am getting this error. I know it must have something to do with the Memory Streams I am creating, and I am disposing of them, so I am not sure what the problem is. My application has two steps...first to acquire an image from a twain device. I am placing the image into a memory stream and then setting that image from the memory stream to a picture box...

public static System.Drawing.Image DIB_ToImage(System.IntPtr hdib)
        {
            System.Drawing.Image convertedImage = null;
            if( hdib != System.IntPtr.Zero ) {
                byte[] imageDataAsByte = new byte[ DIB_Size( hdib ) + 100 ];
                GCHandle byteArrayHandle = GCHandle.Alloc( imageDataAsByte, GCHandleType.Pinned );
                DIB_WriteToBuffer(
                    hdib, TWFF_BMP, byteArrayHandle.AddrOfPinnedObject(), imageDataAsByte.Length );
                byteArrayHandle.Free();
                System.IO.MemoryStream memoryStream = new System.IO.MemoryStream( imageDataAsByte, false );
                System.Drawing.Image temporaryBitmap = System.Drawing.Bitmap.FromStream( ((System.IO.Stream)memoryStream) );
                convertedImage = (System.Drawing.Image)temporaryBitmap.Clone();
                temporaryBitmap.Dispose();
                memoryStream.Dispose();
            }
            return convertedImage;
        }
 

The above code is from a declaration file for a TWAIN program I am using. I am then calling the above...

                if (hdib != IntPtr.Zero)
                {
                    pbImage.Image = EZTwain.DIB_ToImage(hdib);
                    btnSave.Enabled = true;
                    EZTwain.DIB_Free(hdib);
                }
 

This all works fine. But then when I click the save button is when I get the GDI error...

                MemoryStream ms = new MemoryStream();
                pbImage.Image.Save(ms, pbImage.Image.RawFormat);
                byte[] img = ms.GetBuffer();
                ms.Dispose();

The error happens on the line...

pbImage.Image.Save(ms, pbImage.Image.RawFormat);
