Subject: TIFF Sub Images

The TIFF format allows to assign to each Image in the main TIFF IFD with the tag TIFFTAG_SUBIFD = 330 a sub IFD, e.g. containing derivated images of the main image, where the type is indicated by TIFFTAG_SUBFILETYPE (e.g. FILETYPE_REDUCEDIMAGE for a thumbnail or FILETYPE_MASK for a mask).
I have understood how to read TIFFTAG_SUBIFD to receive the subimage IFD file offset. The question is how to load images from that "sub directory" in the TIFF file.
