    Load Image Without Locking File

    I want to load a multipage TIFF image into memory as an Image object but I read that the FromFile method locks the file.

    Can I load this into a stream, close the physical file then manipulate the image there?
    Thanks

    Scott

      Hi,

      Open the image with image.fromstrea m.


      Dim fs As New System.IO.FileS tream("C:\camer a.bmp", IO.FileMode.Ope n)

      Dim img As Image = Image.FromStrea m(fs)

      fs.Close()

      PictureBox1.Ima ge = img

              But this is in the MSDN documentation.

              Remarks
              You must keep the stream open for the lifetime of the Image object.
