NAME

       Image::ExifTool::BZZ - Utility to decode BZZ compressed data

SYNOPSIS

       This module is used by Image::ExifTool

DESCRIPTION

       This module contains definitions required by Image::ExifTool to decode BZZ compressed data in DjVu images.

NOTES

       This code is based on ZPCodec and BSByteStream of DjVuLibre 3.5.21 (see additional copyrights and the first reference below), which are
       covered under the GNU GPL license.

       This is implemented as Image::ExifTool::BZZ instead of Compress::BZZ because I am hoping that someone else will write a proper
       Compress::BZZ module (with compression ability).

NAME

       Image::ExifTool::WritePNG.pl - Write PNG meta information

SYNOPSIS

       These routines are autoloaded by Image::ExifTool::PNG.

DESCRIPTION

       This file contains routines to write PNG metadata.

NOTES

       Compress::Zlib is required to write compressed text.

       Existing text tags are always rewritten in their original form (compressed zTXt, uncompressed tEXt or internation iTXt), so pre-existing
       compressed information can only be modified if Compress::Zlib is available.

       Newly created textual information is written in uncompressed tEXt form by default, or as compressed zTXt if the Compress option is used and
       Compress::Zlib is available (but only if the resulting compressed data is smaller than the original text, which isn't always the case for
       short text strings).
