Image::ExifTool::WritePNG(3) User Contributed Perl Documentation Image::ExifTool::WritePNG(3)

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

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

This file contains routines to write PNG metadata.

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).
