Make specified IFD current IFD
setDirectory(tiffobj,dirNum) sets the image file directory (IFD) specified by dirNum as the current IFD. Tiff object methods operate on the current IFD. The directory index number is one-based.
Open a TIFF file and move to an IFD in the file by specifying its index number. The TIFF file should contain multiple images.
t = Tiff('example.tif','r'); setDirectory(t,2) close(t)
This method corresponds to the TIFFSetDirectory function in the LibTIFF C API. To use this method, you must be familiar with the TIFF specification and technical notes. View this documentation at LibTIFF - TIFF Library and Utilities.
