Please help!

image::exiftool::writepng
Image::ExifTool::WritePNG(3pm) User Contributed Perl Documentation Image::ExifTool::WritePNG(3pm)
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).
