'Parameter is not valid' when creating bitmap with size specified

Question

I am trying to read an image into a bitmap and then create a new bitmap with a specified size, effectively resizing the first bitmap:

                image = new Bitmap(Path + FileName);
                image = new Bitmap(image,new Size(Width, Height));

or by

                Image img = System.Drawing.Image.FromFile(Path + FileName);
                image = new Bitmap(img,Size);

In either case the second line throws an ArgumentException: 'Parameter is not valid'. If i do not specify a size object it works fine.

Answer 1

You can't resize an image that way.  You'll need to use Graphics.DrawImage.  Check this thread for a code example.

Answer 2

Hi i am also getting the same exception "Parameter not valid" in my code

  MemoryStream ms = new MemoryStream(byteArrayIn);
 System.Drawing.Image returnImage = System.Drawing.Image.FromStream(ms);


Actually the byteArrayIn 's length is 169014. And none of value in it is not greater than 255. But i am getting this exception.

So my question is why i am getting this exception? How to solve?

Please help me!!

Thanks!!
