%%
%% 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
% 2016/07/10 v0.6j (DPC)
%  * don't set page size for non standard \mag
% 2017/01/12 v0.6k (DPC)
%  * graphics options as viewport for graphics/4499
