NAME
Image::ExifTool::BuildTagLookup - Build ExifTool tag lookup tables
DESCRIPTION
This module is used to generate the tag lookup tables in
Image::ExifTool::TagLookup.pm and tag name documentation in
Image::ExifTool::TagNames.pod, as well as HTML tag name documentation.
It is used before each new ExifTool release to update the lookup tables
and documentation, but it is not used otherwise. It also performs some
validation and consistency checks on the tag tables.
SYNOPSIS
use Image::ExifTool::BuildTagLookup;
$builder = new Image::ExifTool::BuildTagLookup;
# update Image::ExifTool::TagLookup
$ok = $builder->WriteTagLookup('lib/Image/ExifTool/TagLookup.pm');
# update the tag name documentation
$ok = $builder->WriteTagNames('lib/Image/ExifTool/TagNames.pod','html');
# print some statistics
my $count = $$builder{COUNT};
foreach (sort keys %$count) {
printf "%5d %s\n", $$count{$_}, $_;
}
