# Notes:        Extraction of PICT opcodes is still experimental
#
# - size difference in PixPat color table?? (imagemagick reads only 1 long per entry)
# - other differences in the way imagemagick reads 16-bit images

=head1 NAME

Image::ExifTool::PICT - Read PICT meta information

=head1 SYNOPSIS

This module is used by Image::ExifTool

=head1 DESCRIPTION

This module contains routines required by Image::ExifTool to read PICT
(Apple Picture) images.

=head1 NOTES

Extraction of PICT opcodes is experimental, and is only enabled with the
Verbose or the Unknown option.
