    77 %

    78 % Available class options 

    79 % e.g., \documentclass[10pt,conference]{IEEEtran} 

    80 % 

    81 %             *** choose only one from each category ***

    82 %

    83 % 9pt, 10pt, 11pt, 12pt

    84 %    Sets normal font size. The default is 10pt.

    85 % 

    86 % conference, journal, technote, peerreview, peerreviewca

    87 %    determines format mode - conference papers, journal papers,

    88 %    correspondence papers (technotes), or peer review papers. The user

    89 %    should also select 9pt when using technote. peerreview is like

    90 %    journal mode, but provides for a single-column "cover" title page for

    91 %    anonymous peer review. The paper title (without the author names) is

    92 %    repeated at the top of the page after the cover page. For peer review

    93 %    papers, the \IEEEpeerreviewmaketitle command must be executed (will

    94 %    automatically be ignored for non-peerreview modes) at the place the

    95 %    cover page is to end, usually just after the abstract (keywords are

    96 %    not normally used with peer review papers). peerreviewca is like

    97 %    peerreview, but allows the author names to be entered and formatted

    98 %    as with conference mode so that author affiliation and contact

    99 %    information can be easily seen on the cover page.

   100 %    The default is journal.

   101 %

   102 % draft, draftcls, draftclsnofoot, final

   103 %    determines if paper is formatted as a widely spaced draft (for

   104 %    handwritten editor comments) or as a properly typeset final version.

   105 %    draftcls restricts draft mode to the class file while all other LaTeX

   106 %    packages (i.e., \usepackage{graphicx}) will behave as final - allows

   107 %    for a draft paper with visible figures, etc. draftclsnofoot is like

   108 %    draftcls, but does not display the date and the word "DRAFT" at the foot

   109 %    of the pages. If using one of the draft modes, the user will probably

   110 %    also want to select onecolumn.

   111 %    The default is final.

   112 %

   113 % letterpaper, a4paper

   114 %    determines paper size: 8.5in X 11in or 210mm X 297mm. CHANGING THE PAPER

   115 %    SIZE WILL NOT ALTER THE TYPESETTING OF THE DOCUMENT - ONLY THE MARGINS

   116 %    WILL BE AFFECTED. In particular, documents using the a4paper option will

   117 %    have reduced side margins (A4 is narrower than US letter) and a longer

   118 %    bottom margin (A4 is longer than US letter). For both cases, the top

   119 %    margins will be the same and the text will be horizontally centered. 

   120 %    For final submission to IEEE, authors should use US letter (8.5 X 11in)

   121 %    paper. Note that authors should ensure that all post-processing 

   122 %    (ps, pdf, etc.) uses the same paper specificiation as the .tex document.

   123 %    Problems here are by far the number one reason for incorrect margins.

   124 %    IEEEtran will automatically set the default paper size under pdflatex 

   125 %    (without requiring a change to pdftex.cfg), so this issue is more

   126 %    important to dvips users. Fix config.ps, config.pdf, or ~/.dvipsrc for

   127 %    dvips, or use the dvips -t papersize option instead as needed. See the

   128 %    testflow documentation

   129 %    http://www.ctan.org/tex-archive/macros/latex/contrib/IEEEtran/testflow

   130 %    for more details on dvips paper size configuration.

   131 %    The default is letterpaper.

   132 %

   133 % oneside, twoside

   134 %    determines if layout follows single sided or two sided (duplex)

   135 %    printing. The only notable change is with the headings at the top of

   136 %    the pages.

   137 %    The default is oneside.

   138 %

   139 % onecolumn, twocolumn

   140 %    determines if text is organized into one or two columns per page. One

   141 %    column mode is usually used only with draft papers.

   142 %    The default is twocolumn.

   143 %

   144 % compsoc

   145 %    Use the format of the IEEE Computer Society.

   146 %

   147 % compsocconf

   148 % 	Use the	format of IEEE Computer Society conferencs (CPS)

   149 %

   150 % romanappendices

   151 %    Use the "Appendix I" convention when numbering appendices. IEEEtran.cls

   152 %    now defaults to Alpha "Appendix A" convention - the opposite of what

   153 %    v1.6b and earlier did.

   154 %

   155 % captionsoff

   156 %    disables the display of the figure/table captions. Some IEEE journals

   157 %    request that captions be removed and figures/tables be put on pages

   158 %    of their own at the end of an initial paper submission. The endfloat

   159 %    package can be used with this class option to achieve this format.

   160 %

   161 % nofonttune

   162 %    turns off tuning of the font interword spacing. Maybe useful to those

   163 %    not using the standard Times fonts or for those who have already "tuned"

   164 %    their fonts.

   165 %    The default is to enable IEEEtran to tune font parameters.

   166 %

   187 % \CLASSOPTIONpt

   188 % which will be defined as 9, 10, 11, or 12 depending on the document's

   189 % normalsize point size.

   190 % also, class option peerreviewca implies the use of class option peerreview

   646 % a maximum of 40% and a minimum of 19%.

   651 % However, IEEE allows for a more generous range which reduces the need

   652 % for hyphenation, especially for two column text. Furthermore, IEEE

   653 % tends to use a little bit more nominal space between the words.

   654 % IEEE's interword spacing percentages appear to be:

   655 % 35% nominal

   656 % 23% minimum

   657 % 50% maximum

   658 % (They may even be using a tad more for the largest fonts such as 24pt.)
