TiffFileRead Method (Stream, Int32)
public void Read( Stream stream, int frameIndex )
Public Sub Read ( stream As Stream, frameIndex As Integer )
The same stream or path cannot be used to read and save a TiffFile object. To overwrite an existing TIFF, save the TIFF into a new file, then overwrite the original.
The stream must remain open while accessing TIFF Tags and managing IFD's.
