NAME

6       Image::ExifTool::WritePostScript.pl - Write PostScript meta information
7

SYNOPSIS

9       This file is autoloaded by Image::ExifTool::PostScript.
10

DESCRIPTION

12       This file contains routines to write meta information in PostScript
13       documents.  Six forms of meta information may be written:
14
15           1) PostScript comments (Adobe DSC specification)
16           2) XMP information embedded in a document-level XMP stream
17           3) EXIF information embedded in a Photoshop record
18           4) IPTC information embedded in a PhotoShop record
19           5) ICC_Profile information embedded in an ICCProfile record
20           6) TIFF information embedded in DOS-style binary header
21

NOTES

23       Currently, information is written only in the outer-level document.
24
25       Photoshop will discard meta information in a PostScript document if it
26       has to rasterize the image, and it will rasterize anything that doesn't
27       contain the Photoshop-specific 'ImageData' tag.  So don't expect
28       Photoshop to read any meta information added to EPS images that it
29       didn't create.
30
31       The following two acronyms may be confusing since they are so similar
32       and have different meanings with respect to PostScript documents:
33
34           DSC = Document Structuring Conventions
35           DCS = Desktop Color Separation
