Navigate the image file directories (IFDs) in a TIFF file and get tag or image data from the different IFDs.

Create a Tiff object for the file example.tif which contains three IFDs and display the directory index number for the current IFD in the file.

t = Tiff('example.tif','r');
currentDirectory(t)

ans = 
1

Change the current IFD to 2 and get the value of the ImageDescription tag.

setDirectory(t,2);
getTag(t,'ImageDescription')

ans = 
'First image converted to grayscale.'

Change the current IFD to 3 and get the value of the ImageDescription tag.

setDirectory(t,3);
getTag(t,'ImageDescription')

ans = 
'Credit:  Jeff Mather and Alex Taylor.'

Close the Tiff object.

close(t);
