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/supported/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. % % 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. % % %******* % 09/2005 V1.6c (MDS) changes: % % 1) Changed endfigure/endfloat definitions so as not to cause problems with % preview-LaTeX and other packages. Thanks to Stephan Heuel and David % Kastrup for reporting this problem. % % %******* % 11/2002 V1.6b (MDS) changes: % % 1) Fixed problem with figure captions when using hyperref. Thanks to % Leandro Barajas and Michael Bassetti for reporting this bug. % % 2) Provide a fake nabib command \NAT@parse so that hyperref will not % interfere with the operation of cite.sty. However, as a result citation % numbers will not be hyperlinked. Also, natbib will not be able to work % with IEEEtran. However, this is perhaps the best solution until cite.sty % and hyperref.sty are able to co-exist with each other. % It easy enough to override the fake command via: % \makeatletter % \let\NAT@parse\undefined % \makeatother % % 3) Revised font selection method so as not to have problems when used % with setspace.sty. Thanks to Zhang Yan for reporting this bug. % % 4) Added \special to feed papersize to dvips. Thanks to Moritz Borgmann % for suggesting this feature. % % 5) In addition to the IEEE IED lists, the original IED style list % environments (as is done in article.cls) are now provided as % LaTeXitemize, LaTeXenumerate, and LaTeXdescription. Also, users can % now redefine \makelabel within IEEE IED list controls. There may be % some use for this in specialized applications. Thanks to Eli Barzilay % for suggesting this feature. % % 6) \table* now defaults to \footnotesize text like \table. % % 7) The draft modes now no longer force a pagebreak after the title. % Thanks to Christian Peel for suggesting this change. % % 8) New draftclsnofoot mode is like draftcls, but does not display the % date and the word "DRAFT" at the foot of the page. Thanks to % Christian Peel for suggesting this feature. % % 9) New peerreview and peerreviewca modes with \IEEEpeerreviewmaketitle % command allows for a "cover" titlepage for anonymous peer review. % Except for the cover titlepage, peerreview is much like journal mode. % peerreviewca is like peerreview, but allows the author names to be % entered and formatted as under conference mode so that author % affiliations and contact information can be easily seen on the cover % page. Thanks to Eric Benedict for suggesting this feature. % % %******* % 7/2002 V1.6 (MDS) changes: % % 1) Added conference mode via conference option. Defaults to the traditional % journal mode. i.e., \documentclass[conference]{IEEEtran} % % 2) Added support for A4 paper via new a4paper option. Pdflatex's paper size % lengths are now automatically set to the proper paper size being used. % % 3) Revised margins again. Page text is now horizontally centered. % Conference mode increases the top and bottom margins with the bottom % margin being slightly larger. For A4 paper, the top margin and text % typesetting will not change from those of US letter paper, but the side % margins will be smaller and the bottom margin will be larger than that of % US letter. All per IEEE specs. % % 4) Fixed footnote line spacing anomaly in draft mode. % Thanks to Alberto Rodriguez for reporting this bug. % % Also, slightly revised footnote and \thanks note spacing. % Set \interfootnotelinepenalty=10000 to prevent LaTeX % from breaking footnotes across multiple pages or columns. % % 5) Fixed bug that caused overwritten photo areas and sometimes anomalous % spacing when a new paragraph was started within a biography. Also, % the presence of \par's, new lines or spaces at the beginning of % abstract, keywords, biography, or biographynophoto will no longer % affect the first word spacing. % Thanks to Eric Durant for reporting this bug. % % The biography environment now does a better job in preventing % a biography photo area from being broken across pages or columns. % % 6) Fixed whitespace between \cite entries bug. i.e., % both \cite{einstein24, knuth84} and \cite{einstein24,knuth84} % are now valid. \cite is now a robust command as it should be. % IEEEtran now no longer defines the old non-standard \shortcite or % \citename. % % The base IEEEtran.cls does not sort citation numbers or produce ranges % for three or more consecutive numbers. However, V1.6 of IEEEtran.cls % now pre-defines the following format control macros to facilitate easy % use with Donald Arseneau's cite.sty package (tested with cite.sty V3.9): % % \def\citepunct{], [} % \def\citedash{]--[} % % cite.sty is standard on most LaTeX sytems and can be obtained from % www.ctan.org. Thanks to Donald Arseneau for creating cite.sty, providing % the required format arguments to produce the IEEE style. and % designing a cite interface capable of handling the IEEE citation % style. % % Note: Historically, IEEE has wanted authors to "hardcode" symbolics. % (i.e., replace all \cite{} with fixed [x]). However, it now seems that % most electronic manuscript submissions to IEEE are in .pdf format, and % as such, do not require the LaTeX document reference numbers to be hard % coded. If an author is required to submit actual LaTeX files, I do % recommend that the bibliography file (.bbl) be copied into the .tex % document and the \bibliographystyle{} and \bibliography{} commands be % commented out so that the .tex file does not depend on (potentially % lengthy and/or confidential) external bibliography database files. % % 7) Adjusted some spacing parameters. The spacing above and below equations % has been revised (to a typical IEEE value). \jot now has a decent value. % The title text is now exactly 24pt. (On a related note, \fontsubfuzz has % been increased to 0.9pt to prevent annoying font substitution warnings % when using the Computer Modern fonts that use the 24.88pt size.) % In V1.6, \small is now 8.5pt in 9pt docs because \footnotesize is 8pt. % For 9pt docs, you should probably go ahead and use \footnotesize when you % need text a little smaller than \normalsize. % The interword spacing has been adjusted to be extremely close to that % which IEEE uses. You can use a new class option, nofonttune, if you need % to disable the adjusting of the interword spacing. This adjustment and % an increase to \hyphenpenalty have greatly reduced the amount of % hyphenation in a typical paper. % The baselineskip for the normalsize fonts has been tweaked to reduce % underfull vboxes on journal paper columns with only paragraphs. % Conference mode does the same thing but by also tweaking the \textheight % slightly off 9.25in (IEEE spec) to ensure an integer number of lines per % page. Draft (also draftcls) mode has also been revised to reduce % underfull vbox warnings. However, draft mode can still produce underfull % vboxes (a direct result of the increase in line spacing and margins) if: % A non-normalsize font occupies an entire column (abstract and index terms % take up a whole column by themselves); or the beginning of a section % occurs near the end of a column and cannot be squeezed into the bottom, % etc. This is normal as draft mode's liberal spacings cannot guarantee % perfect formatting. % % 8) New biographynophoto environment for biographies without photos. % Usage: % % \begin{biographynophoto}{author name} % biography text here % \end{biographynophoto} % % 9) Fixed bug that produced multiple table of contents entries for papers % with more than one biography. Also, biography now works better with % hyperref. % %10) New \sublargesize font size command provides for 11pt text in a 10pt % document. (Needed for things like author names.) For documents not % using 10pt normal size text, \sublargesize is currently identical % to \large. % %11) New \IEEEmembership command to provide correct font to indicate IEEE % membership for journal papers. % %12) Fixed author name line overflow problem when in journal mode. This % problem had been introduced in V1.5 in my rush to get \and to work for % conferences. \and is unneeded (and invalid) in journal mode. For % conference mode, \and will work as expected and features an optional % spacing argument. i.e., \and[\hspace{5ex}] % \and will default (recommended) to using \hfill which will result in % equal spacing between author blocks. % %13) New \authorblockN, \authorblockA and \authorrefmark commands to % facilitate easy formatting of author names, affiliations and cross % reference symbols, respectively, when in conference mode. These % three commands are to be used only for conference papers. % In conference mode, \author text is placed within a modified tabular % environment (somewhat like article.cls). So, within \author in conference % mode, you should not try to enclose multiple \\ within an environment or % command (other than the argument braces of \authorblockX{}). For example: % % \author{\authorblockN{{John Doe \\ Jane Doe}}} % WRONG! % % will generate an error. % % Note that font size/attribute changes will now persists across \\ within % \author. (But, not across author blocks nor across \and.) % However, with the new commands, there should be no need to alter any % font attributes within \author. All text sizing and spacing within % \author{} and the author block commands is per IEEE specs for both % conference and journal modes. (In conference mode, the author names % are only very slightly larger than the affiliations which are in normal % size.) For specialized applications you can alter the justification of % author lines by placing \hfill at the beginning or at the end of a line. % The interline spacing within \author is determined by the font attributes % that are in effect at the end of each line within author. % %14) Because the titles and author name blocks use different font sizes/styles % from the main text, it was possible that two column papers with titles that % span both columns (standard journal and conference papers, but not technotes) % with certain numbers of lines for the title and authors' name/affiliations % can cause underfull vbox problems (paragraphs with large spacings between % them) in the second column of the main text on the title page - if there were % no new sections, equations or figures in this column (they would provide some % needed rubber spacing). The use of things like special paper notices and % publisher ID marks also affected this issue. The problem could not happen % in the first column because the first column has a rubber length around the % heading of the first section. Furthermore, problems seldom occurred on pages % after the first as the margins had been chosen not to cause it with the popular % font sizes. Rubber lengths after the author names would not fix this problem. % Auto-calculating a "good" spacing after the title is a tad difficult % to do in LaTeX. However, I am pleased to report that V1.6 has this new % capability - "dynamically determined title spacing". IEEEtran will now % measure the height of all the title and author text in \maketitle % and then calculate a rigid (non-rubber) spacer to follow that meets % IEEE specs and also produces a \textheight on the title page that ensures % an integer number of normalsized lines on the rest of the page. Single % column papers, and two column papers with the title entirely in column % one (technotes) do not need dynamic rigid spacing and therefore use % standard rubber spacers. % % Note: This problem can still crop up if you use floats that span both % columns (i.e., figure*). It has been a decade+ long limitation with LaTeX % that the stretchable portion of \dbltextfloatsep is ignored. % If you get a problem with underful vbox warnings and paragraphs that "are % pulled apart" on page with a float that spans both columns, tweak the % space between the figure and the main text a little: % % \vskip 5pt % \end{figure*} % % If you can't find a value that fixes both columns, you are going to % have to put a rubber spacer somewhere in one or both of the columns. % %15) Because of change #14 above, those of you using \pubid will, as of V1.6, % have to place it *before* \maketitle in order for it have the intended % affect. The dynamic spacer algorithm must see if you are using \pubid when % \maketitle is called. \pubidadjcol works as before except that it now % has additional logic to prevent it from doing anything if \pubid was never % called. % %16) In some unusual, non-standard circumstances, an author may desire to % alter the spacing after the title area or put some unusual text above % the main text. For instance, to stop a bad break when a new section % occurs right at the start of the second page. This is difficult to do % when the title spans both columns of two column text since LaTeX treats % such title text as a type of float. A new command, \IEEEaftertitletext{}, % gives access to the end of that produced by \maketitle. The types of % things that can go into \IEEEaftertitletext are the same as those into % \twocolumn[] - no \par, but \\ are OK. There is no restriction on the % range of spacings that can be used. % i.e., \IEEEaftertitletext{\vspace{-100pt}} will push the main text well % into the title and \IEEEaftertitletext{\vspace{100pt}} will push it far down % the page. You will have complete control. If used, place % \IEEEaftertitletext{} before \maketitle like \title and \author. IEEEtran's % dynamic title spacing intentionally does not take into consideration the % contents of \IEEEaftertitletext{} when determining the spacer after the title % area (otherwise it would try to second guess you), so the user will have % manually adjust the height of the contents in \IEEEaftertitletext{} if the % problem discussed in #14 above should develop. A safe bet is to keep % the height of contents of \IEEEaftertitletext{} to integer multiples of % \baselineskip, i.e., \IEEEaftertitletext{\vspace{-1\baselineskip}} % % Because it can result in an IEEE nonstandard format, the use of % \IEEEaftertitletext{} is discouraged. Possible uses include (1) the use of % IEEEtran for non-IEEE work with different title spacing requirements, % or (2) as an emergency manual override if a problem should develop in % IEEEtran's automatic spacing algorithm. % %17) completely rewritten \PARstart to: % a. no longer have problems when the user begins an environment % within the paragraph that uses \PARstart. % b. auto-detect and use the current font family % c. revise handling of the space at the end of the first word so that % interword glue will now work as normal. % d. produce correctly aligned edges for the (two) indented lines. % % Because the current font family is now auto-detected, there is no % longer any need for \CMPARstart - it is now the same as \PARstart. % %18) There is now a new "open box" Q.E.D. symbol (\QEDopen) as well as the % original default (\QED) closed one (\QEDclosed). Some journals use % the open form. To make \proof use the open form, just do: % \renewcommand{\QED}{\QEDopen} % %19) Additional \typeout{} notices added to warn the user when unusual % settings/commands are detected or as reminders to avoid common errors % when in conference mode. % %20) IEEEtran now provides \abovecaptionskip and \belowcaptionskip skip % registers because article class provides them and some packages % may error if they are missing. However, IEEEtran only uses % \abovecaptionskip for actual caption spacing. % %21) Fixed bug that prevented users from redefining the section headings % to use arabic digits. Thanks to Richardt H. Wilkinson for reporting % this bug. % %22) Code cleaned up to be more efficient with the use of TeX registers; % removed some old LaTeX 2.09 code; revised option processing to % LaTeX2e standard; eliminated unwanted "phantom" spaces in some % environments. % %23) Added new \IEEEeqnarray, \IEEEeqnarraybox, \IEEEeqnarrayboxm and % \IEEEeqnarrayboxt environments to provide superior alternatives to the % standard LaTeX \eqnarray, \array and \tabular. Additional new support % commands include \IEEEeqnarraydecl, \IEEEeqnarrayboxdecl, % \IEEEeqnarraymathstyle, \IEEEeqnarraytextstyle, \yesnumber. \IEEEnonumber, % \IEEEyesnumber, \IEEEyessubnumber, \IEEEeqnarraynumspace, \IEEEeqnarraymulticol, % \IEEEeqnarrayomit, \IEEEeqnarraydefcol, \IEEEeqnarraydefcolsep, \IEEEeqnarrayseprow, % \IEEEeqnarrayseprowcut, \IEEEeqnarrayrulerow, \IEEEeqnarraydblrulerowcut, % \IEEEeqnarraystrutmode, \IEEEeqnarraystrutsize, \IEEEeqnarraystrutsizeadd, % \IEEEvisiblestrutstrue, \IEEEvisiblestrutsfalse and \IEEEstrut. % These are documented in the user's guide. % %24) V1.6 changed back to using () around theorem names (which are also now in italics) % as this is what IEEE is using now. Thanks to Christian Peel for reporting this. % Also, when section numbers are used as the first part of theorem numbers, display % them in arabic, not Roman. % %25) New \IEEEtriggeratref{X} command allows a page break to be triggered just % before the given reference number "X". This is most useful when balancing % the columns on the last page and a \newpage between references is desired. % \IEEEtriggercmd{X} allows a different command to be executed at trigger. % % %******* % 7/2001 V1.5 (MDS) changes: % % % 1) Fixed \and within \author bug: (! Misplaced \crcr. \endtabular ->\crcr) % Thanks to Rainer Dorsch for discovering and reporting that \and % did not work. % % 2) Fixed the biography environment so that if a biography's text is shorter % than the area allocated for the photo, a collision with the next % biography does not occur. You can now put real graphics (using the % graphicx package) into the biography photo box with a new optional % argument of the biography command! For example: % % \begin{biography}[{\includegraphics[width=1in,height=1.25in,clip,keepaspectratio]{./tux.eps}}]{Linux Penguin} % % will use the specified graphic as the author's photo. The photo area is % exactly 1in wide by 1.25in high - as is done in IEEE Transactions. Try % to keep the same 4:5 aspect ratio if scanning/cropping your photos. % Note the need for the extra set of enclosing braces around the % \includegraphics. Without it, The LaTeX parser may get confused when it % sees the \includegraphics's brackets within the biography's optional % argument. Due to the length of the \includegraphics command, you may wish % to define your own shorthand form of it. I have not done so with IEEEtran % to prevent dependence on the graphicx package. If you do not use the % optional argument, or leave it empty, a standard frame box with the % words "Place Photo Here" will be used. If you want the space to remain % completely empty, you can do: % % \begin{biography}[\mbox{}]{The Invisible Man} % % The interface to biography's optional argument is into a % 1in X 1.25in minipage in which the argument text is centered both % horizontally and vertically: % % \begin{minipage}[b][1.25in][c]{1in}% % \centering % #1% % \end{minipage} % % Within the biography environment, \unitlength is set to 1in. % With this in mind, you can even design your own custom frameboxes. % For instance: % % \begin{biography}[\framebox(1,1.25){\parbox[][\height][c]{0.9in}{\centering PLACE\\ PHOTO\\ HERE}}]{Author Name} % % will yield the same type of result as the default photo box. % % Thanks to Herbert Voss for discovering the collision bug, suggesting the ability % to handle graphics and providing some prototype code. % % % %******* % 3/2001 V1.4 (MDS) changes: % % % 1) New "draftcls" and "final" options have been added. % Thanks to Dragan Cvetkovic for suggesting an option like draftcls. % % 2) Documentation changes to reflect the fact that this IEEEtran.cls % is no longer beta test. % % 3) Slightly revised caption sizes. Figure and table captions are now % in \footnotesize, not \small as before. % % 4) Allow user to control figure caption justification. IEEEtran.cls % normally defaults to left justified as is done in Transactions. % However, for conferences, you may wish to issue the command: % \centerfigcaptionstrue % in the preamble. Short (less than one line long) figure captions % will then be centered. Multi-line figure captions will always be % properly left justified. V1.6: This is already done for you when % using the conference mode. % % % %******* % 1/2001 V1.3 % Michael Shell (MDS) made extensive changes and additions: % % % BUGS FIXED (and many others too numerous to mention!): % 1) Fixed improper alignment with itemized, enumerated and % description lists. Added new controls to these three % environments so that it is easy to get the alignment IEEE % uses. Furthermore, the itemize, enumerate and description lists % no longer force a new paragraph to begin at the end the list % (\par). (Sometimes lists are used within paragraphs.) % % 2) JVH's fixes now allow things like $\mathbf{N}(0,P(0))$ % to work properly without needing the extra braces: % ${\mathbf{N}}(0,P(0))$. There is no longer any dependence % on the "rawfonts" and "oldlfont" packages. Thanks Juergen! % % 3) Fixed underfull hbox errors and incorrect reference number % alignment when the number of references in the bibliography % exceeded 9 entries (which is almost every paper!). % % 4) Removed dependence on the LaTeX sizexx.clo files. % Now, 9pt documents should work correctly even on systems that % lack a size9.clo file. This is most often used in conjunction % with the option "technote" for "correspondence" papers like those % in IEEE Transactions on Information Theory. For virtually all % other papers, 10pt is used and so it is the default. % Some improper font sizes have been corrected. \footnotesize is % now 8pt in 9pt docs, so footnotes in technotes should be the % correct size now. % % 5) Added \interlinepenalty within the bibliography section to discourage % LaTeX from breaking within a reference. IEEE almost never breaks within % a reference and when they do it is usually in technotes % (correspondence papers). You may get an underfull vbox warning in the % bibliography indicating that the spacing just before the "REFERENCES" % section is larger than normal, but the final result will be more like % what IEEE will publish. See the comments in the BIBLIOGRAPHY section % around line 2034 below if you want to change this behavior. % % 6) No longer "blows up" when you use \paragraph and have a table % of contents. % % 7) Theorem environment changed, (but for V1.6, back to the old way, sigh). % % 8) Figure captions adjusted: IEEE left (not center) justifies % figure captions (for journals) and does not indent figure caption text. % % 9) Adjusted some spacings in the table of contents(TOC))/list-of-figures/ % list-of-tables so that section/table numbers will not so easily % collide with the titles. Section VIII was usually the worst offender. % Still doesn't right justify the section numbers, but neither does % article.cls (This must be why LaTeX likes the x.y.z section numbering % scheme unlike I, II, III, etc. of IEEE. ) % It may be "normal" as it is (left justified). sigh. % %10) Now uses "index terms" now as a heading instead of "keywords". % Furthermore, the "index terms" and "abstract" headings are in bold % italic.
