  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. % romanappendices
  148. % Use the "Appendix I" convention when numbering appendices. IEEEtran.cls
  149. % now defaults to Alpha "Appendix A" convention - the opposite of what
  150. % v1.6b and earlier did.
  151. %
  152. % captionsoff
  153. % disables the display of the figure/table captions. Some IEEE journals
  154. % request that captions be removed and figures/tables be put on pages
  155. % of their own at the end of an initial paper submission. The endfloat
  156. % package can be used with this class option to achieve this format.
  157. %
  158. % nofonttune
  159. % turns off tuning of the font interword spacing. Maybe useful to those
  160. % not using the standard Times fonts or for those who have already "tuned"
  161. % their fonts.
  162. % The default is to enable IEEEtran to tune font parameters.

  889. %
  890. %
  891. % IEEE seems to use at least two different values by
  892. % which ITEMIZED list labels are indented to the right
  893. % For The Journal of Lightwave Technology (JLT) and The Journal
  894. % on Selected Areas in Communications (JSAC), they tend to use
  895. % an indention equal to \parindent. For Transactions on Communications
  896. % they tend to indent ITEMIZED lists a little more--- 1.3\parindent.
  897. % We'll provide both values here for you so that you can choose
  898. % which one you like in your document using a command such as:
  899. % setlength{\IEEEilabelindent}{\IEEEilabelindentB}
  900. \newdimen\IEEEilabelindentA
  901. \IEEEilabelindentA \parindent
  902. \newdimen\IEEEilabelindentB
  903. \IEEEilabelindentB 1.3\parindent
  904. % However, we'll default to using \parindent
  905. % which makes more sense to me
  906. \newdimen\IEEEilabelindent
  907. \IEEEilabelindent \IEEEilabelindentA
  908. % This controls the default amount the enumerated list labels
  909. % are indented to the right.
  910. % Normally, this is the same as the paragraph indention
  911. \newdimen\IEEEelabelindent
  912. \IEEEelabelindent \parindent
  913. % This controls the default amount the description list labels
  914. % are indented to the right.
  915. % Normally, this is the same as the paragraph indention
  916. \newdimen\IEEEdlabelindent
  917. \IEEEdlabelindent \parindent
  918. % This is the value actually used within the IED lists.
  919. % The IED environments automatically set its value to
  920. % one of the three values above, so global changes do
  921. % not have any effect
  922. \newdimen\IEEElabelindent
  923. \IEEElabelindent \parindent
  924. % The actual amount labels will be indented is
  925. % \IEEElabelindent multiplied by the factor below
  926. % corresponding to the level of nesting depth
  927. % This provides a means by which the user can
  928. % alter the effective \IEEElabelindent for deeper
  929. % levels
  930. % There may not be such a thing as correct "standard IEEE"
  931. % values. What IEEE actually does may depend on the specific
  932. % circumstances.
  933. % The first list level almost always has full indention.
  934. % The second levels I've seen have only 75% of the normal indentation
  935. % Three level or greater nestings are very rare. I am guessing
  936. % that they don't use any indentation.
  937. \def\IEEElabelindentfactori{1.0} % almost always one
  938. \def\IEEElabelindentfactorii{0.75} % 0.0 or 1.0 may be used in some cases

  943. % value actually used within IED lists, it is auto
  944. % set to one of the 6 values above
  945. % global changes here have no effect
  946. \def\IEEElabelindentfactor{1.0}
  947. % This controls the default spacing between the end of the IED
  948. % list labels and the list text, when normal text is used for
  949. % the labels.
  950. \newdimen\IEEEiednormlabelsep
  951. \IEEEiednormlabelsep 0.6em
  952. % This controls the default spacing between the end of the IED
  953. % list labels and the list text, when math symbols are used for
  954. % the labels (nomenclature lists). IEEE usually increases the
  955. % spacing in these cases
  956. \newdimen\IEEEiedmathlabelsep
  957. \IEEEiedmathlabelsep 1.2em
  958. % This controls the extra vertical separation put above and
  959. % below each IED list. IEEE usually puts a little extra spacing
  960. % around each list. However, this spacing is barely noticeable.
  961. \newskip\IEEEiedtopsep
  962. \IEEEiedtopsep 2pt plus 1pt minus 1pt
  963. % This command is executed within each IED list environment
  964. % at the beginning of the list. You can use this to set the
  965. % parameters for some/all your IED list(s) without disturbing
  966. % global parameters that affect things other than lists.
  967. % i.e., renewcommand{\IEEEiedlistdecl}{\setlength{\labelsep}{5em}}
  968. % will alter the \labelsep for the next list(s) until
  969. % \IEEEiedlistdecl is redefined.
  970. \def\IEEEiedlistdecl{\relax}
  971. % This command provides an easy way to set \leftmargin based
  972. % on the \labelwidth, \labelsep and the argument \IEEElabelindent
  973. % Usage: \IEEEcalcleftmargin{width-to-indent-the-label}
  974. % output is in the \leftmargin variable, i.e., effectively:
  975. % \leftmargin = argument + \labelwidth + \labelsep

  980. % This command provides an easy way to set \labelwidth to the
  981. % width of the given text. It is the same as
  982. % \settowidth{\labelwidth}{label-text}
  983. % and useful as a shorter alternative.

  986. \def\IEEEsetlabelwidth#1{\settowidth{\labelwidth}{#1}}
  987. % When this command is executed, IED lists will use the
