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 IRB resource which is
    located in the APP13 record of JPEG files. This module contains the definitions to read this
    information.

NOTES
    Photoshop IRB 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.
