NAME

6       Image::ExifTool::Photoshop - Read/write Photoshop IRB meta information
7

SYNOPSIS

9       This module is loaded automatically by Image::ExifTool when required.
10

DESCRIPTION

12       Photoshop writes its own format of meta information called a Photoshop
13       IRB resource which is located in the APP13 record of JPEG files.  This
14       module contains the definitions to read this information.
15

NOTES

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