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.
