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.

NAME

       Image::ExifTool::WritePostScript.pl - Write PostScript meta information

SYNOPSIS

       This file is autoloaded by Image::ExifTool::PostScript.

DESCRIPTION

       This file contains routines to write meta information in PostScript documents.  Six forms of meta information may be written:

	   1) PostScript comments (Adobe DSC specification)
	   2) XMP information embedded in a document-level XMP stream
	   3) EXIF information embedded in a Photoshop record
	   4) IPTC information embedded in a PhotoShop record
	   5) ICC_Profile information embedded in an ICCProfile record
	   6) TIFF information embedded in DOS-style binary header

NOTES

       Currently, information is written only in the outter-level document.

       Photoshop will discard meta information in a PostScript document if it has to rasterize the image, and it will rasterize anything that
       doesn't contain the Photoshop-specific 'ImageData' tag.	So don't expect Photoshop to read any meta information added to EPS images that it
       didn't create.

       The following two acronyms may be confusing since they are so similar and have different meanings with respect to PostScript documents:

	   DSC = Document Structuring Conventions
	   DCS = Desktop Color Separation
