Image::ExifTool::WriteUser3Contributed Perl DocumeImage::ExifTool::WritePNG(3)

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 international 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).
