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 re-
turned.
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 defini-
tions to that list, so that libtiff is aware of those tags. See
