NAME

Image::ExifTool::Photoshop - Read/write Photoshop IRB meta information

SYNOPSIS

This module is loaded automatically by Image::ExifTool when required.

DESCRIPTION

Photoshop writes its own format of meta information called a Photoshop resource which is located in the record of files. This module contains the definitions to read this information.

NOTES

Photoshop blocks may have an associated resource name. These names are usually just an empty string, but if not empty they are displayed in the verbose level 2 (or greater) output. A special "SetResourceName" flag may be set to '1' in the tag information hash to cause the resource name to be appended to the value when extracted. If this is done, the returned value has the form ``VALUE/#NAME#/''. When writing, the writer routine looks for this syntax (if "SetResourceName" is defined), and and uses the embedded name to set the name of the new resource. This allows the resource names to be preserved when copying Photoshop information via user-defined tags.
