+%% Usage
+%% =====
+%%
+%% It may be used by specifying the pdftex option to any of the
+%% supported packages, for example:
+%%
+%% \usepackage[pdftex]{graphicx}
+%%
+%% * pdfTeX determines the bounding box of the images by means of
+%% itself. Therefore the bounding box options should not be used.
+%% In this cases a warning is issued and viewport is used instead.
+%% * Option "page" (graphicx) for selecting a page of a multipage
+%% PDF document.
+%% * \pagecolor is supported. \nopagecolor disables the page color.
+%% * Option "quiet" (graphicx/experimental): log messages are suppressed.
+%% * Option "resolution" (graphicx/experimental): this sets
+%% \pdfimageresolution, see pdfTeX documentation.
+%% * Option "print" (graphicx/experimental): specifies an alternate
+%% print image (bitmaps only), see PDF specification.
+%% * pdftex.def can be used under plain-TeX with miniltx support.
+%%
+%% "Experimental" means that these features can change or vanish
+%% in later versions.

+% History
+% ...
+% 2000/04/20 v0.02s:
+% * gray color model directly supported (HO).
+% 2000/05/02 v0.02t:
+% * \pagecolor supported (HO).
+% 2000/05/12 v0.02u:
+% * support for multipage pdf files, option `page' added (HO).
+% 2000/05/31 v0.02v:
+% * Option `page' is defined at begin document,
+% if package `keyval' is loaded after `pdftex.def'.
+% 2000/06/16 v0.03a:
+% * Added Heiko to author list (DPC).
+% 2000/08/31 v0.03b:
+% * support for alternate print images: option `print' added (HO).
+% * This feature is not supported by Ghostscript, xpdf, or AR3.
+% * The images should have the same dimensions/resolution.
+% * Two experimental options added (HO):
+% * `quiet': log messages are suppressed.
+% * `resolution': sets \pdfimageresolution.
+% Because these options are not supported by graphicx,
+% they have to be set after \usepackage{graphicx}, eg.
+% \setkeys{Gin}{quiet,resolution=300}
+% Option `quiet' (for pdftex) can be make known to graphic{s,x}
+% with this line in graphics.cfg:
+% \DeclareOption{quiet}{\let\Gin@log\@gobble}
+% Caution: both options are experimental and can be
+% change in next versions!
+% * \pdfpage{width,height} are only set, if \paperwidth
+% is defined (HO).
+% 2000/09/04 v0.03c
+% * Redefinition of `natwidth' and `natheight' \AtBeginDocument (HO).
+% 2000/09/14 v0.03d
+% * Fixes for `viewport' and `trim' (HO).
+% * Clip support added for viewport and trim (HO).
+% 2000/09/14 v0.03e
+% * Options `bbllx', `bblly', `bburx', `bbury' disabled,
+% option `bb' redirected with a warning to `viewport' (HO).
+% 2000/11/10 v0.03f
+% * Bug, that produces an error message, if package `graphics'
+% is used (introduced in 0.03d), fixed: If \Gin@vllx is not
+% defined (graphics), then clipping and the moves of options
+% viewport/trim are silently disabled (HO).
+% 2001/05/25 v0.03g
+% * \pdfpagewidth and \pdfpageheight are not set to zero,
+% if \paperwidth and \paperheight are not set (HO).
+% 2001/09/01 v0.03h
+% * Compatibilty for miniltx.tex, problems fixed:
+% \@ifpackageloaded, \PackageWarning, \PackageWarningNoLine,
+% \@currname.
+% 2001/11/29 v0.03i
+% * Problem with \if@inlabel (plain format) fixed.
+% 2002/06/18 v0.03j
+% * Contribution by P\'etiard Fran\c{c}ois <petiard@math.univ-fcomte.fr>:
+% Improvement of \Ginclude@mps (support of viewport and clip).
+% 2002/06/19 v0.03k
+% * Correction by P\'etiard Fran\c{c}ois for \GPT@DoEndClip.
+% 2005/06/15 v0.03l
+% * \usebox patch fixed (\aftergroup part removed) (HO).
+% 2005/06/20 v0.03m
+% * .tif support is removed for pdfTeX >= 1.10a (HO).
+% 2006/02/23 v0.03n
+% * Compatibility for plain-TeX: file can be loaded multiple times;
+% colorfix is not applied for undefined macros (HO).
+% 2006/02/24 v0.03o
+% * Catcode protections mainly because of babel's shorthands (HO).
+% 2006/03/02 v0.03p
+% * \pagecolor support for plain-TeX fixed (HO).
+% 2006/05/17 v0.03q
+% * Error message if ConTeXt's supp-pdf.tex is missing and
+% support of MPS files is not available (Markus Kohm = MK, HO).
+% 2006/06/06 v0.03r
+% * \nopagecolor/\no@page@color added (HO).
+% 2006/07/16 v0.03s (HO)
+% * LPPL 1.3c.
+% * A little usage.
+% * Test for \MessageBreak changed (comp.text.tex,
+% message id: <44baca88$0$10529$9b4e6d93@newsread4.arcor-online.net>).
+% 2006/08/14 v0.03t (HO)
+% * Extensions added: .jpeg, .JPG, .JPEG, .PNG, .PDF
+% No variants for .tif, because TIFF support is no longer available.
+% No need for uppercase variant of .mps.
+% 2007/01/01 v0.04a (HO)
+% * Support of color stack, introduced in pdfTeX 1.40.0.
+% * Support of transform matrix commands of pdfTeX 1.40.0.
+% * The argument for option `page' can be a register.
+% 2007/01/02 v0.04b (HO)
+% * Internal change: Switching of color stacks is easier by using
+% \@pdfcolorstack for the stack number. Thus this command
+% should be redefined, if someone wants to use another color stack
+% (e.g. for footnotes). \main@pdfcolorstack should not be changed
+% for this purpose.
+% 2007/01/06 v0.04c (HO)
+% * Support for JBIG2 added (pdfTeX 1.40.0).
+% 2007/01/08 v0.04d (HO)
+% * Bug fix: .mps forgotten for extension list if pdfTeX >= 1.40.0
+% * .jbig2 and .jb2 are not listed in the extension list
+% if \pdfminorversion < 4. Thus \pdfminorversion should have
+% the correct value, if pdftex.def is loaded.
+% 2007/03/15 v0.04e (HO)
+% * Missing comma in \Gin@extensions added (found by Reinhard Kotucha).
+% 2007/04/06 v0.04f (HO)
+% * Fix for \pagecolor, text before page color can lead to an invalid
+% page stream. Therefore "page" is now used instead of "direct"
+% as modifier for \pdfliteral.
+% * Boolean option `resetcolor' added (pdfTeX >= 0.12n).
+% The current color is used for PDF or MPS images, unless
+% the images contain their own color settings.
+% If option `resetcolor' is set to `true', then the current color
+% is reset to \normalcolor during image inclusion.
+% 2007/04/17 v0.04g (HO)
+% * Small improvement of robustness of \pagecolor
+% and using e-TeX if available.
+% 2007/06/12 v0.04h (HO)
+% * Fix for \pagecolor: v0.04f uses keyword `page' for \pdfliteral,
+% but this keyword is not available before pdfTeX 1.30.0.
+% 2007/12/04 v0.04i (HO)
+% * Fatal error is avoided if image file does not exists.
+% 2007/12/06 v0.04j (HO)
+% * Option xmpfile added for adding metadata (experimental).
+% 2008/07/16 v0.04k (HO)
+% * \LoadMetaPostSpecialExtensions
+% loads additional support for MetaPost images (transparency)
+% by loading supp-mpe.tex and supp-mis.tex
+% (method posted in comp.text.tex by Jeremy Lea).
+% As side effect MetaPost images are put in separate objects
+% and are not inlined in the page stream.
+% Status: experimental.
+% 2008/09/08 v0.04l (HO)
+% * Adds an error message, if pdfTeX is called in DVI mode.
+% * Aborts loading of the package with an error message,
+% if pdfTeX is missing.
+% 2009/08/25 v0.04m (HO)
+% * Catcodes are preserved and initialized for loading of
+% pdftex.def and ConTeXt's support files.
+% * ConTeXt's support files have now the extension `.mkii' instead
+% of `.tex'.
+% 2010/02/14 v0.04n (HO)
+% * \GPT@catcodes extended for xmlTeX (pdftex.def loads
+% supp-pdf.mkii at begin document where xmlTeX's catcodes
+% are already active).
+% 2010/03/11 v0.04o (HO)
+% * Ensure that \undefined is undefined during loading of
+% ConTeXt files.
+% 2010/03/12 v0.04p (HO)
+% * \undefined is also undefined during conversion of MPS.
+% 2010/04/14 v0.04q (HO)
+% * Optimizations for rotating and scaling:
+% * remove unnecessary identity transformations
+% * numbers are normalized
+% 2010/04/15 v0.04r (HO)
+% * Fix for scale values without integer part.
+% 2010/09/09 v0.05a (HO)
+% * Option `pagebox' added for specifying the pdf page box
+% of the included image. Values are `mediabox', `cropbox',
+% `bleedbox', `trimbox' and `artbox'. Default is `cropbox'. (MS/HO)
+% * Option `interpolate' added for bitmaps, see PDF specification.
+% Values are `true' or `false', default is `false'.
+% * Option `decodearray' added for bitmaps, see PDF specification,
+% key /Decode of image dictionaries. The value for option
+% `decodearray' is the value for /Decode without `[' and ']'.
+% * Option `maskarray' added for bitmaps, see PDF specification,
+% key /Mask of image dictionaries with array as value.
+% The value of `maskarray' is the array value for /Mask
+% without `[' and ']'.
+% * Option `intent' added for the rendering intent of bitmap
+% images, see PDF specification, key /Intent of image
+% dictionaries. The value is a name without a leading slash,
+% the standard names of the PDF specification:
+% `AbsoluteColorimetric', `RelativeColorimetric',
+% `Saturation', `Perceptual'.
+% * Options `ocobjnum' and `ocobjref' are hooks for those who wants
+% to work with optional content. The options can be used for both
+% bitmap and PDF images and are unsupported for MPS.
+% The optional content dictionary is given by an external
+% object. Option `ocobjnum' expects the number of that object
+% (e.g. \pdflastobj). It's a positive integer (greater than zero).
+% Option `ocobjref' takes the full object reference
+% (positive integer, followed by ` 0 R' in case of pdfTeX).
+% Other drivers might support `ocobjref' as well, in case of
+% PostScript/pdfmark drivers, the object is usually referenced by
+% a name in curly braces.
+% * Tiff support removed for driver versions between 1.10a and 1.30.
+% 2010/09/14 v0.05b (HO)
+% * Fix, \pagecolor got broken accidentally (in v0.05a).
+% 2010/11/26 v0.05c (HO)
+% * \stockwidth and \stockheight of class `memoir' respected.
+% 2011/01/28 v0.05d (HO)
+% * Patching trig.sty is improved by doing it earlier in some
+% cases, e.g. if one of class `memoir', package `scrlfile' or
+% package `filehook' is loaded.
+% 2011/04/21 v0.06a (HO)
+% * The use info on the screen goes with an information
+% entry in the .log file that also tells the requested
+% width (feature request of Axel Berger).
+% * Use of packages `infwarerr' and `ltxcmds'.
+% 2011/04/25 v0.06b (HO)
+% * Fix in \GPT@NormalizeNumber.
+% * Date fixed in \ProvidesFile.
+% 2011/05/18 v0.06c (HO)
+% * The ConTeXt support files `supp-pdf.*' and `supp-mpe.*' do
+% not prevent reloading. Therefore `pdftex.def' only tries to load
+% them if \convertMPtoPDF and \assignMPStransparency are not
+% available. This fixes a compatibilty issue with class `combine'.
+% 2011/05/27 v0.06d (HO)
+% * Fix for v0.06a, package `ltxcmds' was not loaded in plain TeX.
+% 2016/01/23 v0.6e (DPC)
+% * Move EPS handler here from graphics.cfg
+% 2016/06/04 v0.6f (DPC)
+% * support graphcs/color option (no)setpagesize
+% 2016/06/15 v0.6g (DPC)
+% * typo
+% 2016/06/17 v0.6h (DPC)
+% * guards for contributed packages and plain TeX
+%
+% Prefix of internal commands for this file `pdftex.def':
