The default is 10pt. +% +% conference, journal, technote, peerreview, peerreviewca +% determines format mode - conference papers, journal papers, +% correspondence papers (technotes), or peer review papers. The user +% should also select 9pt when using technote. peerreview is like +% journal mode, but provides for a single-column "cover" title page for +% anonymous peer review. The paper title (without the author names) is +% repeated at the top of the page after the cover page. For peer review +% papers, the \IEEEpeerreviewmaketitle command must be executed (will +% automatically be ignored for non-peerreview modes) at the place the +% cover page is to end, usually just after the abstract (keywords are +% not normally used with peer review papers). peerreviewca is like +% peerreview, but allows the author names to be entered and formatted +% as with conference mode so that author affiliation and contact +% information can be easily seen on the cover page. +% The default is journal. +% +% draft, draftcls, draftclsnofoot, final +% determines if paper is formatted as a widely spaced draft (for +% handwritten editor comments) or as a properly typeset final version. +% draftcls restricts draft mode to the class file while all other LaTeX +% packages (i.e., \usepackage{graphicx}) will behave as final - allows +% for a draft paper with visible figures, etc. draftclsnofoot is like +% draftcls, but does not display the date and the word "DRAFT" at the foot +% of the pages. If using one of the draft modes, the user will probably +% also want to select onecolumn. +% The default is final. +% +% letterpaper, a4paper, cspaper +% determines paper size: 8.5in X 11in, 210mm X 297mm or 7.875in X 10.75in. +% Changing the paper size in the standard journal and conference modes +% will not alter the typesetting of the document - only the margins will +% be affected. In particular, documents using the a4paper option will +% have reduced side margins (A4 is narrower than US letter) and a longer +% bottom margin (A4 is longer than US letter). For both cases, the top +% margins will be the same and the text will be horizontally centered. +% For the compsoc conference and draft modes, it is the margins that will +% remain constant, and thus the text area size will vary, with changes in +% the paper size. +% The cspaper option is the special ``trim'' paper size (7.875in x 10.75in) +% used in the actual publication of Computer Society journals. Under +% compsoc journal mode, this option does not alter the typesetting of the +% document. Authors should invoke the cspaper option only if requested to +% do so by the editors of the specific journal they are submitting to. +% For final submission to the IEEE, authors should generally use US letter +% (8.5 X 11in) paper unless otherwise instructed. Note that authors should +% ensure that all post-processing (ps, pdf, etc.) uses the same paper +% specificiation as the .tex document. Problems here are by far the number +% one reason for incorrect margins. IEEEtran will automatically set the +% default paper size under pdflatex (without requiring any change to +% pdftex.cfg), so this issue is more important to dvips users. Fix +% config.ps, config.pdf, or ~/.dvipsrc for dvips, or use the +% dvips -t papersize option instead as needed. For the cspaper option, +% the corresponding dvips paper name is "ieeecs". +% See the testflow documentation +% http://www.ctan.org/tex-archive/macros/latex/contrib/IEEEtran/testflow +% for more details on dvips paper size configuration. +% The default is letterpaper. +% +% oneside, twoside +% determines if layout follows single sided or two sided (duplex) +% printing. The only notable change is with the headings at the top of +% the pages. +% The default is oneside. +% +% onecolumn, twocolumn +% determines if text is organized into one or two columns per page. One +% column mode is usually used only with draft papers. +% The default is twocolumn. +% +% comsoc, compsoc, transmag +% Use the format of the IEEE Communications Society, IEEE Computer Society +% or IEEE Transactions on Magnetics, respectively. +% +% romanappendices +% Use the "Appendix I" convention when numbering appendices. IEEEtran.cls +% now defaults to Alpha "Appendix A" convention - the opposite of what +% v1.6b and earlier did. +% +% captionsoff +% disables the display of the figure/table captions. Some IEEE journals +% request that captions be removed and figures/tables be put on pages +% of their own at the end of an initial paper submission. The endfloat +% package can be used with this class option to achieve this format. +% +% nofonttune +% turns off tuning of the font interword spacing. Maybe useful to those +% not using the standard Times fonts or for those who have already "tuned" +% their fonts. +% The default is to enable IEEEtran to tune font parameters. +% +% +%---------- +% Available CLASSINPUTs provided (all are macros unless otherwise noted): +% \CLASSINPUTbaselinestretch +% \CLASSINPUTinnersidemargin +% \CLASSINPUToutersidemargin +% \CLASSINPUTtoptextmargin +% \CLASSINPUTbottomtextmargin +% +% Available CLASSINFOs provided: +% \ifCLASSINFOpdf (TeX if conditional) +% \CLASSINFOpaperwidth (macro) +% \CLASSINFOpaperheight (macro) +% \CLASSINFOnormalsizebaselineskip (length) +% \CLASSINFOnormalsizeunitybaselineskip (length) +% +% Available CLASSOPTIONs provided: +% all class option flags (TeX if conditionals) unless otherwise noted, +% e.g., \ifCLASSOPTIONcaptionsoff +% point size options provided as a single macro: +% \CLASSOPTIONpt +% which will be defined as 9, 10, 11, or 12 depending on the document's +% normalsize point size. +% also, class option peerreviewca implies the use of class option peerreview +% and classoption draft implies the use of class option draftcls + + + + + +\ProvidesClass{IEEEtran}[2015/08/26 V1.8b by Michael Shell] +\typeout{-- See the "IEEEtran_HOWTO" manual for usage information.} +\typeout{-- http://www.michaelshell.org/tex/ieeetran/} +\NeedsTeXFormat{LaTeX2e} + +% IEEEtran.cls version numbers, provided as of V1.3 +% These values serve as a way a .tex file can +% determine if the new features are provided. +% The version number of this IEEEtrans.cls can be obtained from +% these values. i.e., V1.4 +% KEEP THESE AS INTEGERS! i.e., NO {4a} or anything like that- +% (no need to enumerate "a" minor changes here) +\def\IEEEtransversionmajor{1} +\def\IEEEtransversionminor{8} + + +% hook to allow easy changeover to IEEEtran.cls/tools.sty error reporting +\def\@IEEEclspkgerror{\ClassError{IEEEtran}} + + +% These do nothing, but provide them like in article.cls +\newif\if@restonecol +\newif\if@titlepage + + +% class option conditionals +\newif\ifCLASSOPTIONonecolumn \CLASSOPTIONonecolumnfalse +\newif\ifCLASSOPTIONtwocolumn \CLASSOPTIONtwocolumntrue + +\newif\ifCLASSOPTIONoneside \CLASSOPTIONonesidetrue +\newif\ifCLASSOPTIONtwoside \CLASSOPTIONtwosidefalse + +\newif\ifCLASSOPTIONfinal \CLASSOPTIONfinaltrue +\newif\ifCLASSOPTIONdraft \CLASSOPTIONdraftfalse +\newif\ifCLASSOPTIONdraftcls \CLASSOPTIONdraftclsfalse +\newif\ifCLASSOPTIONdraftclsnofoot \CLASSOPTIONdraftclsnofootfalse + +\newif\ifCLASSOPTIONpeerreview \CLASSOPTIONpeerreviewfalse +\newif\ifCLASSOPTIONpeerreviewca \CLASSOPTIONpeerreviewcafalse + +\newif\ifCLASSOPTIONjournal \CLASSOPTIONjournaltrue +\newif\ifCLASSOPTIONconference \CLASSOPTIONconferencefalse +\newif\ifCLASSOPTIONtechnote \CLASSOPTIONtechnotefalse + +\newif\ifCLASSOPTIONnofonttune \CLASSOPTIONnofonttunefalse + +\newif\ifCLASSOPTIONcaptionsoff \CLASSOPTIONcaptionsofffalse + +\newif\ifCLASSOPTIONcomsoc \CLASSOPTIONcomsocfalse +\newif\ifCLASSOPTIONcompsoc \CLASSOPTIONcompsocfalse +\newif\ifCLASSOPTIONtransmag \CLASSOPTIONtransmagfalse + +\newif\ifCLASSOPTIONromanappendices \CLASSOPTIONromanappendicesfalse + + +% class info conditionals + +% indicates if pdf (via pdflatex) output +\newif\ifCLASSINFOpdf \CLASSINFOpdffalse + + +% V1.6b internal flag to show if using a4paper +\newif\if@IEEEusingAfourpaper \@IEEEusingAfourpaperfalse +% V1.6b internal flag to show if using cspaper +\newif\if@IEEEusingcspaper \@IEEEusingcspaperfalse + + +% IEEEtran class scratch pad registers +% dimen +\newdimen\@IEEEtrantmpdimenA +\newdimen\@IEEEtrantmpdimenB +\newdimen\@IEEEtrantmpdimenC +% count +\newcount\@IEEEtrantmpcountA +\newcount\@IEEEtrantmpcountB +\newcount\@IEEEtrantmpcountC +% token list +\newtoks\@IEEEtrantmptoksA + +% we use \CLASSOPTIONpt so that we can ID the point size (even for 9pt docs) +% as well as LaTeX's \@ptsize to retain some compatability with some +% external packages +\def\@ptsize{0} +% LaTeX does not support 9pt, so we set \@ptsize to 0 -

This command +% is more general than the older \@IEEEdynamictitlevspace it replaces. +% +% The star form has no effect at present, but is reserved for future use. +% +% If the optional argument [output dimen register] is given, the calculated +% vspace height is stored in the given output dimen (or skip) register +% and no other action is taken, otherwise the object followed by a vspace* +% of the appropriate height is evaluated/output. +% +% The optional object decl (declarations) is code that is evaluated just +% before the object's height is evaluated. Its intented purpose is to allow +% for the alteration or disabling of code within the object during internal +% height evaluation (e.g., \long\def\thanks#1{\relax} ). +% This special code is not invoked if/when the object is rendered at the end. +% +% The nominal vspace is the target value of the added vspace and the minimum +% vspace is the lower allowed limit. The vspacer will be the value that achieves +% integral overall height, in terms of the given unit height, that is closest +% to the nominal vspace and that is not less than the specified minimum vspace. +% +% The line spacing algorithm of TeX is somewhat involved and requires special +% care with regard to the first line of a vertical list (which is indicated +% when \prevdepth is -1000pt or less). top baselineskip specifies the +% baselineskip or topskip used prior to the object. If the height of the +% first line of the object is greater than the given top baselineskip, then +% the top baselineskip is subtracted from the height of the first line and +% that difference is considered along with the rest of the object height +% (because the object will be shifted down by an amount = +% top line height - top baselineskip). Otherwise, the height of the first line +% of the object is ignored as far as the calculations are concerned. +% This algorithm is adequate for objects that appear at the top of a page +% (e.g., titles) where \topskip spacing is used. +% +% However, as explained on page 78 of the TeXbook, interline spacing is more +% complex when \baselineskip is being used (indicated by \prevdepth > +% -1000pt). The four optional parameters offset, prevdepth, lineskip limit and +% lineskip are assumed to be equal to be 0pt, \prevdepth, \lineskiplimit and +% \lineskip, respectively, if they are omitted. +% +% The prevdepth is the depth of the line before the object, the lineskip limit +% specifies how close the top of the object can come to the bottom of the +% previous line before \baselineskip is ignored and \lineskip is inserted +% between the object and the line above it. Lineskip does not come into +% play unless the first line of the object is high enough to "get too close" +% (as specified by lineskiplimit) to the line before it. The the prevdepth, +% lineskip limit, and lineskip optional parameters are not needed for the +% first object/line on a page (i.e., prevdepth <= -1000pt) where the simplier +% \topskip spacing rules are in effect. +% +% Offset is a manual adjustment that is added to the height calculations of +% object irrespective of the value of \prevdepth. It is useful when the top +% baselineskip will result in a noninteger unit height object placement even +% if the object itself has integral height. e.g., a footnotesize baselineskip +% is used before the object, thus an offset of, say -3pt, can be given as a +% correction. + +% Common combinations of these parameters include: +% +% top baselineskip: (and default values for offset, prevdepth, etc.) +% \topskip % for objects that appear at the top of a page +% \maxdimen % always ignore the height of the top line +% 0pt % always consider any positive height of the top line +% +% for objects to appear inline in normal text: +% top baselineskip = \baselineskip +% +% set prevdepth = -1000pt and top baselineskip = 0pt to consider the +% overall height of the object without any other external skip +% consideration + +\newif\if@IEEEquantizevspacestarform % flag to indicate star form +\newif\if@IEEEquantizevspaceuseoutdimenreg % flag to indicate output dimen register is to be used +% Use our own private registers because the object could contain a +% structure that uses the existing tmp scratch pad registers +\newdimen\@IEEEquantizeheightA +\newdimen\@IEEEquantizeheightB +\newdimen\@IEEEquantizeheightC +\newdimen\@IEEEquantizeprevdepth % need to save this early as can change +\newcount\@IEEEquantizemultiple +\newbox\@IEEEquantizeboxA + + +\def\@IEEEquantizevspace{\@ifnextchar [{\@IEEEquantizevspaceuseoutdimenregtrue\@@IEEEquantizevspace}{\@IEEEquantizevspaceuseoutdimenregfalse\@@IEEEquantizevspace[]}} + + +\long\def\@@IEEEquantizevspace[#1]#2{\relax +% acquire and store +% #1 optional output dimen register +% #2 object +\edef\@IEEEquantizeoutdimenreg{#1}\relax +% allow for object specifications that contain parameters +\@IEEEtrantmptoksA={#2}\relax +\long\edef\@IEEEquantizeobject{\the\@IEEEtrantmptoksA}\relax +\@ifnextchar [{\@@@IEEEquantizevspace}{\@@@IEEEquantizevspace[\relax]}} + +\long\def\@@@IEEEquantizevspace[#1]#2{\relax +% acquire and store +% [#1] optional object decl, is \relax if not given by user +% #2 top baselineskip +% allow for object decl specifications that have parameters +\@IEEEtrantmptoksA={#1}\relax +\long\edef\@IEEEquantizeobjectdecl{\the\@IEEEtrantmptoksA}\relax +\edef\@IEEEquantizetopbaselineskip{#2}\ivIEEEquantizevspace} + +% acquire optional argument set and store +% [offset][prevdepth][lineskip limit][lineskip] +\def\ivIEEEquantizevspace{\@ifnextchar [{\@vIEEEquantizevspace}{\@vIEEEquantizevspace[0pt]}} +\def\@vIEEEquantizevspace[#1]{\edef\@IEEEquantizeoffset{#1}\@ifnextchar [{\@viIEEEquantizevspace}{\@viIEEEquantizevspace[\prevdepth]}} +\def\@viIEEEquantizevspace[#1]{\@IEEEquantizeprevdepth=#1\relax\@ifnextchar [{\@viiIEEEquantizevspace}{\@viiIEEEquantizevspace[\lineskiplimit]}} +\def\@viiIEEEquantizevspace[#1]{\edef\@IEEEquantizelineskiplimit{#1}\@ifnextchar [{\@viiiIEEEquantizevspace}{\@viiiIEEEquantizevspace[\lineskip]}} +\def\@viiiIEEEquantizevspace[#1]{\edef\@IEEEquantizelineskip{#1}\@ixIEEEquantizevspace} + +% main routine +\def\@ixIEEEquantizevspace#1#2#3{\relax +\edef\@IEEEquantizeunitheight{#1}\relax +\edef\@IEEEquantizenomvspace{#2}\relax +\edef\@IEEEquantizeminvspace{#3}\relax +% \@IEEEquantizeoutdimenreg +% \@IEEEquantizeobject +% \@IEEEquantizeobjectdecl +% \@IEEEquantizetopbaselineskip +% \@IEEEquantizeoffset +% \@IEEEquantizeprevdepth +% \@IEEEquantizelineskiplimit +% \@IEEEquantizelineskip +% \@IEEEquantizeunitheight +% \@IEEEquantizenomvspace +% \@IEEEquantizeminvspace +% get overall height of object +\setbox\@IEEEquantizeboxA\vbox{\begingroup\@IEEEquantizeobjectdecl\@IEEEquantizeobject\relax\endgroup}\relax +\@IEEEquantizeheightA\ht\@IEEEquantizeboxA\relax +% get height of first line of object +\setbox\@IEEEquantizeboxA\vtop{\begingroup\@IEEEquantizeobjectdecl\@IEEEquantizeobject\relax\endgroup}\relax +\@IEEEquantizeheightB\ht\@IEEEquantizeboxA\relax +\ifdim\@IEEEquantizeprevdepth>-1000pt\relax % prevdepth > -1000pf means full baselineskip\lineskip rules in effect +% lineskip spacing rule takes effect if height of top line > baselineskip -
