.SH "NAME"
Image::ExifTool::WritePostScript.pl \- Write PostScript meta information
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
This file is autoloaded by Image::ExifTool::PostScript.
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
This file contains routines to write meta information in PostScript
documents.  Six forms of meta information may be written:
.PP
.Vb 6
\&    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
.Ve
.SH "NOTES"
.IX Header "NOTES"
Currently, information is written only in the outer-level document.
.PP
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 \s-1EPS\s0 images that it didn't create.
.PP
The following two acronyms may be confusing since they are so similar and
have different meanings with respect to PostScript documents:
.PP
.Vb 2
\&    DSC = Document Structuring Conventions
\&    DCS = Desktop Color Separation
