Make subIFD the current IFD
Open a TIFF file and read the value of the
SubIFD tag in the current IFD. The
SubIFD tag contains byte offsets that specify the location of subIFDs in the IFD.
t = Tiff('example.tif','r');
Read the value of the
SubIFD tag to get the subdirectory offsets. Multiple values in the
offsets array indicate multiple subdirectories.
offsets = getTag(t,'SubIFD')
offsets = uint64 90114
Navigate to the first subIFD. If you have multiple subdirectories, then you can set any one of the subdirectories as the current directory.
t— Tiff object
Tiff object representing a TIFF file. Use the
Tiff function to create the object.
offset— Offset from current directory
Offset from the current directory, specified as a positive integer. Specify offset value in bytes from the start of the file.
Get value of offset from the
