Hello all, I'm a bit confused with interpreting SubIFDs tag value. Each value of N values in SubIFDs tag is an offset (from the beginning of the TIFF file, as always) to a child IFD. But is each value of N values an offset to a single child IFD, or to the first IFD from a linked list of IFDs? When I read each of these N child IFDs, am I supposed to interpret NextIFDOffset field and read next directory from this position for each of child IFDs? Could anyone put some light on this, please? Thanks in advance, kind regards, mikk
