Hi there,
In trying to use the tag extension schemes in "./contrib/tags" I came across a not so obvious limitation in the lines
#define FIELD_SETLONGS 3
#define FIELD_LAST (32*FIELD_SETLONGS-1)
u_long td_fieldsset[FIELD_SETLONGS];
in tif_dir.h.
Here FIELD_LAST indicates the maximum number of tags you may define in libtiff. If, for instance, you want to read Exif files it seems you need to increase FIELD_SETLONGS to accomodate the large number of tags.
