NAME

       TIFFCustomTagList - returns information about the custom tag list

SYNOPSIS

          #include <tiffio.h>

       int TIFFGetTagListCount(TIFF *tif)

       uint32_t TIFFGetTagListEntry(TIFF *tif, int tag_index)

DESCRIPTION

       TIFFGetTagListCount() returns the number of entries in the custom tag list.

       TIFFGetTagListEntry()  returns the tag number of the (n.th - 1) entry within the custom tag list.  If the
       tag_index is larger or equal to the number of entries in the  tag  list  0xFFFFFFFF  (=(uint32_t(-1))  is
       returned.

NOTE

       The  known  tags  to  libtiff are define as 'named' tags and a lot of them as custom tags. The custom tag
       definitions are handled in an internal custom tag list. This list can also  be  extended  by  adding  tag
       definitions to that list, so that libtiff is aware of those tags.  See Defining Application Tags
