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% determines paper size: 8.5in X 11in or 210mm X 297mm. CHANGING THE PAPER% SIZE 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 final submission to IEEE, authors should use US letter (8.5 X 11in)% paper. 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 a 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. 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.%% compsoc% Use the format of the IEEE Computer Society.%% compsocconf% Use the format of IEEE Computer Society conferencs (CPS)%% 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}[2007/03/05 V1.7a 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{7}% 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\ifCLASSOPTIONcompsoc \CLASSOPTIONcompsocfalse\newif\ifCLASSOPTIONcompsocconf \CLASSOPTIONcompsocconffalse\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% IEEEtran class scratch pad registers% dimen\newdimen\@IEEEtrantmpdimenA\newdimen\@IEEEtrantmpdimenB% count\newcount\@IEEEtrantmpcountA\newcount\@IEEEtrantmpcountB% 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 -
