NAME

       Image::ExifTool::Pentax - Pentax/Asahi maker notes tags

SYNOPSIS

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

DESCRIPTION

       This module contains definitions required by Image::ExifTool to interpret Pentax and Asahi maker notes in EXIF information.

NOTES

       I couldn't find a good source for Pentax maker notes information, but I've managed to discover a fair bit of information by analyzing
       sample images downloaded from the internet, and through tests with my own Optio WP and K10D, and with help provided by other ExifTool users
       (see "ACKNOWLEDGEMENTS").

       The Pentax maker notes are stored in standard EXIF format, but the offsets used for some of their cameras are wacky.  The Optio 330 gives
       the offset relative to the offset of the tag in the directory, the Optio WP uses a base offset in the middle of nowhere, and the Optio 550
       uses different (and totally illogical) bases for different menu entries.  Very weird.  (It wouldn't surprise me if Pentax can't read their
       own maker notes!)  Luckily, there are only a few entries in the maker notes which are large enough to require offsets, so this doesn't
       affect much useful information.	ExifTool attempts to make sense of this fiasco by making an assumption about where the information should
       be stored to deduce the correct offsets.

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 outer-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
