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).

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).

In a shell script I would like to use a compressed file name, i.e. with suffix of .Z, as a file input $1. After the file in uncompressed, I would like to use the file name without the .Z . How do I do this?
Thank you. (8 Replies)
I was wondering if there's a way to search within a file that's been compressed. i.e. if file a is inside file a.zip or a.gz, is there a a command that will retrieve the string of data I'm looking for in file a, and list which compressed file it found it in?
Please help!
Thanks. (8 Replies)

Hi All,
Is there is any way to find the size of compressed file without doing decompression. The size should give the original uncompressed data size
Thanks
