<p> <b>Please note:</b> If you're writing your own plugin for mimeTeX, |
|
please don't write php code using <b>system( )</b>, or any other |
|
shell escape mechanism, just to cache images. Use mimeTeX's |
|
<b>-DCACHEPATH=\"<i>path/</i>\"</b> |
|
<a href="#options">compile option</a> instead. |
|
<b>system( )</b> raises security |
|
issues, either real ones if used carelessly, or just in the minds of |
|
system administrators. Either way, I've received many emails from |
|
people unable to use mimeTeX because of unnecessary <b>system( )</b> |
|
calls prohibited by security-conscious sysadmins. MimeTeX itself poses |
|
minimal risk when used as illustrated above, but you're responsible |
|
for any plugin/wrapper script you write around it. </p> |

<h3> <a name="valignment"> |

Vertical alignment<font size=5>...</font></a> </h3> |
|
<p> An image like |
|
<a href="#preview"><img id="imageAV1" onclick="eqntext('imageAV1')" |
|
src="../cgi-bin/mimetex.cgi? |
|
\normalsize f(x)=\int\limits_{-\infty}^xe^{-t^2}dt" |
|
alt="" border=0 align=middle></a> |
|
doesn't look as good as the same image |
|
<a href="#preview"><img id="imageAV2" onclick="eqntext('imageAV2')" |
|
src="../cgi-bin/mimetex.cgi? |
|
\normalsize f(x)=\int\limits_{-\infty}^xe^{-t^2}dt" |
|
alt="" border=0 style="Vertical-Align:-11px"></a> |
|
that's vertically aligned with your surrounding text. |
|
Along with several standard |
|
<a href="http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html"> |
|
HTTP header fields</a>, mimeTeX also emits a special |
|
<b>Vertical-Align: –<i>nn</i></b> |
|
header, where <b>–<i>nn</i></b> is the number of pixels |
|
(usually negative as illustrated) needed for a |
|
<b>style="Vertical-Align: –<i>nn</i> px"</b> |
|
attribute in the <b><img></b> tag used to |
|
render your expression. </p> |
|
|
|
<p> But mimeTeX's special Vertical-Align: header |
|
is unrecognized and ignored by your browser. You have to get the |
|
header, interpret it, and write the corresponding <img> tag. |
|
The only feasible way to do all this is using a scripting language, |
|
as illustrated by the following, rather naive, php code </p> |
|
<pre class="medium" style="margin-top:.5em;margin-bottom:.5em" |
|
> <?php |
|
$mimetexurl = "http://www.<i>yourdomain</i>.com/cgi-bin/mimetex.cgi?"; |
|
function verticalalign( $expression ) { |
|
global $mimetexurl; |
|
// note: curl_init() stops at the first whitespace char in $url argument |
|
$expression = ereg_replace(" ","~",$expression); // so remove whitespace |
|
$url = $mimetexurl . $expression; |
|
$valign = "0"; |
|
$ch = curl_init( $url ); |
|
curl_setopt( $ch, CURLOPT_RETURNTRANSFER, true ); |
|
curl_setopt( $ch, CURLOPT_HEADER, true ); |
|
$gif = curl_exec( $ch ); |
|
$errno = curl_errno( $ch ); |
|
curl_close( $ch ); |
|
if ( $errno == 0 ) { |
|
$fields = explode("Vertical-Align:",$gif); |
|
$vfield = trim($fields[1]); |
|
$fldlen = strspn($vfield,"+-0123456789"); |
|
$valign = substr($vfield,0,$fldlen); } |
|
return $valign; |
|
} |
|
function mimetextag( $expression ) { |
|
global $mimetexurl; |
|
$valign = verticalalign($expression); |
|
$url = $mimetexurl . $expression; |
|
echo ' <img src="',$url,'" '; |
|
echo ' style="Vertical-Align:',$valign,'px" '; |
|
echo ' alt="" border=0>', "\n"; |
|
} |
|
?></pre> |
|
|
|
<p> Now you can write |
|
<?php mimetextag('\frac12\left(a^2+b^2\right)'); ?> |
|
wherever you want to see |
|
<a href="#preview"><img id="imageAV5" onclick="eqntext('imageAV5')" |
|
src="../cgi-bin/mimetex.cgi? |
|
\normalsize\frac12\left(a^2+b^2\right)" |
|
alt="" border=0 style="Vertical-Align:-5px"></a> |
|
correctly aligned. <!-- Besides making you escape backslashes |
|
(each \ must be written \\), --> |
|
This code calls mimeTeX twice to render each expression, |
|
once to get the Vertical-Align: header and build an |
|
<img> tag, and then again to render that tag. |
|
If you're a good php programmer and write better code, |
|
please email me a copy. </p> |
|
|
|
<p> If you're using mimeTeX's |
|
<b>-DCACHEPATH=\"<i>path</i>/\"</b> |
|
<a href="#options">compile option</a>, prefix your |
|
<b><i>path</i>/</b> with a leading <b>%</b> and write |
|
<b>-DCACHEPATH=\"%<i>path</i>/\"</b> instead. |
|
That leading <b>%</b> won't become part of your cache |
|
directory's <b><i>path</i>/</b>, but it will signal mimeTeX |
|
to cache headers along with each image. |
|
Otherwise, the Vertical-Align: information is lost, |
|
and attempts to align cached images will fail. </p> |

|
<li> And there are various additional syntactic and cosmetic |

differences between LaTeX and mimeTeX. For example, |

bounding boxes for mimeTeX's character bitmaps don't |

|
<ul> |
|
<li> An unmatched left brace <b>{</b> is matched |
|
by mimeTeX with a "phantom" right brace <b>}</b> |
|
that's imagined to be at the end of your expression. </li> |
|
<li> Likewise, an unmatched <b>\left(</b>, |
|
or <b>\left\{</b> or <b>\left\</b><i>anything</i>, |
|
is matched by mimeTeX with a "phantom" <b>\right.</b> |
|
at the end of your expression. </li> |
|
<li> On the other hand, an unmatched right brace <b>}</b> |
|
is displayed in place, as if you had typed \rbrace. </li> |
|
<li> But an unmatched <b>\right\</b><i>anything</i> |
|
is interpreted as an |
|
<a href="http://www.forkosh.com/mimetexmanual.html?abbreviations" |
|
target="_top">abbreviation</a> for <b>\</b>rightarrow |
|
followed by <b>\</b><i>anything</i>. For example, |

<b>\leff( abc \right) def</b> renders |

<p> <b>Please note:</b> If you're writing your own plugin for mimeTeX, |
|
please don't write php code using <b>system( )</b>, or any other |
|
shell escape mechanism, just to cache images. Use mimeTeX's |
|
<b>-DCACHEPATH=\"<i>path/</i>\"</b> |
|
<a href="#options">compile option</a> instead. |
|
<b>system( )</b> raises security |
|
issues, either real ones if used carelessly, or just in the minds of |
|
system administrators. Either way, I've received many emails from |
|
people unable to use mimeTeX because of unnecessary <b>system( )</b> |
|
calls prohibited by security-conscious sysadmins. MimeTeX itself poses |
|
minimal risk when used as illustrated above, but you're responsible |
|
for any plugin/wrapper script you write around it. </p> |
|
|
|
<h3> <a name="valignment"> |
|
Vertical alignment<font size=5>...</font></a> </h3> |
|
<p> An image like |
|
<a href="#preview"><img id="imageAV1" onclick="eqntext('imageAV1')" |
|
src="../cgi-bin/mimetex.cgi? |
|
\normalsize f(x)=\int\limits_{-\infty}^xe^{-t^2}dt" |
|
alt="" border=0 align=middle></a> |
|
doesn't look as good as the same image |
|
<a href="#preview"><img id="imageAV2" onclick="eqntext('imageAV2')" |
|
src="../cgi-bin/mimetex.cgi? |
|
\normalsize f(x)=\int\limits_{-\infty}^xe^{-t^2}dt" |
|
alt="" border=0 style="Vertical-Align:-26px"></a> |
|
that's vertically aligned with your surrounding text. |
|
Along with several standard |
|
<a href="http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html"> |
|
HTTP header fields</a>, mimeTeX also emits a special |
|
<b>Vertical-Align: –<i>nn</i></b> |
|
header, where <b>–<i>nn</i></b> is the number of pixels |
|
(usually negative as illustrated) needed for a |
|
<b>style="Vertical-Align: –<i>nn</i> px"</b> |
|
attribute in the <b><img></b> tag used to |
|
render your expression. This Vertical-Align: header |
|
is obtained by placing the directive <b>\depth</b> |
|
anywhere in your expression. </p> |
|
|
|
<p> But mimeTeX's special Vertical-Align: header |
|
is unrecognized and ignored by your browser. You have to get the |
|
header, interpret it, and write the corresponding <img> tag. |
|
The only feasible way to do all this is using a scripting language, |
|
as illustrated by the following, rather naive, php code </p> |
|
<pre class="medium" style="margin-top:.5em;margin-bottom:.5em" |
|
> <?php |
|
$mimetexurl = "http://www.<i>yourdomain</i>.com/cgi-bin/mimetex.cgi?"; |
|
function verticalalign( $expression ) { |
|
global $mimetexurl; |
|
// note: curl_init() stops at the first whitespace char in $url argument |
|
$expression = ereg_replace(" ","~",$expression); // so remove whitespace |
|
$url = $mimetexurl . "\depth~" . $expression; |
|
$valign = "0"; |
|
$ch = curl_init( $url ); |
|
curl_setopt( $ch, CURLOPT_RETURNTRANSFER, true ); |
|
curl_setopt( $ch, CURLOPT_HEADER, true ); |
|
$gif = curl_exec( $ch ); |
|
$errno = curl_errno( $ch ); |
|
curl_close( $ch ); |
|
if ( $errno == 0 ) { |
|
$fields = explode("Vertical-Align:",$gif); |
|
$vfield = trim($fields[1]); |
|
$fldlen = strspn($vfield,"+-0123456789"); |
|
$valign = substr($vfield,0,$fldlen); } |
|
return $valign; |
|
} |
|
function mimetextag( $expression ) { |
|
global $mimetexurl; |
|
$valign = verticalalign($expression); |
|
$url = $mimetexurl . "\depth~" . $expression; |
|
echo ' <img src="',$url,'" '; |
|
echo ' style="Vertical-Align:',$valign,'px" '; |
|
echo ' alt="" border=0>', "\n"; |
|
} |
|
?></pre> |
|
|
|
<p> Now you can write |
|
<?php mimetextag('\frac12\left(a^2+b^2\right)'); ?> |
|
wherever you want to see |
|
<a href="#preview"><img id="imageAV5" onclick="eqntext('imageAV5')" |
|
src="../cgi-bin/mimetex.cgi? |
|
\normalsize\frac12\left(a^2+b^2\right)" |
|
alt="" border=0 style="Vertical-Align:-7px"></a> |
|
correctly aligned. Note that the php code automatically |
|
prepends <b>\depth</b> to your expression for you. |
|
<!-- Besides making you escape backslashes |
|
(each \ must be written \\), --> |
|
(Also note that this code calls mimeTeX twice to render each |
|
expression, once to get the Vertical-Align: header and build |
|
an <img> tag, and then again to render that tag. |
|
If you're a good php programmer and write better code, |
|
please email me a copy.) </p> |
|
|
|
<p> If you're using mimeTeX's |
|
<b>-DCACHEPATH=\"<i>path</i>/\"</b> |
|
<a href="#options">compile option</a>, you can request |
|
that all images be cached with Vertical-Align: headers, |
|
whether or not they contain the \depth directive. Prefix your |
|
<b><i>path</i>/</b> with a leading <b>%</b> and write |
|
<b>-DCACHEPATH=\"%<i>path</i>/\"</b> instead. |
|
That leading <b>%</b> won't become part of your cache |
|
directory's <b><i>path</i>/</b>, but it will signal mimeTeX |
|
to cache headers along with each image. (In this case, |
|
the directive <b>\nodepth</b> suppresses |
|
mimeTeX's header caching for that image.) |
|
<!-- Otherwise, the Vertical-Align: information is lost, |
|
and attempts to align cached images will fail. --> </p> |

mimeTeX correctly generates images whose QUERY_STRING's |

mimeTeX can block requests from HTTP_REFERER's that |
|
don't match your HTTP_HOST, <i>i.e.</i>, from pages on |
|
different servers than your mimetex.cgi image. <br> |
|
The default value of REFLEVELS is 3, |
|
meaning the topmost three levels of HTTP_REFERER and |
|
HTTP_HOST must match. For example, phy.cam.ac.uk matches |
|
math.cam.ac.uk because they share the same topmost three |
|
levels cam.ac.uk. So a page installed at the physics |
|
department can use a mimetex.cgi installed at the math |
|
department. If you always want a complete match, compile |
|
mimeTeX with <b>-DREFLEVELS=99</b> or any large number. |
|
If HTTP_REFERER is not found, then the same 24 |
|
character limit discussed immediately above remains in effect. <br> |

To completely disable the REFLEVELS check, |

compile mimeTeX with <b>-DNOREFCHECK</b> (or with |

<b>-DREFLEVELS=0</b>). Or, if you supply a specific |

Optionally, the overlay is horizontally <b><i>offset</i></b> |
The superimposed <b><i>overlay</i></b> is centered, both |

That means the <b><i>base</i></b> remains positioned in your expression |

just as if it had been rendered alone, while the <b><i>overlay</i></b> |

Vertical <b><i>overlay</i></b> offset is relative to the |

<h3> <a name="evaluate">\eval{ }<font size=5>...</font></a> </h3> |
|
|
|
<p class="continue"> mimeTeX can evaluate arithmetic expressions, |
|
which is a feature intended primarily for use in |
|
<a href="#newcommands">\newcommand's</a> discussed above. |
|
Expressions can be built up from the following elements </p> |
|
<ul> |
|
<li> digits <b>0</b>-<b>9</b> |
|
and numbers composed of uninterrupted (no whitespace) |
|
sequences of digits, </li> |
|
<li> binary operators |
|
<b>+</b>, <b>-</b>, <b>*</b>, <b>/</b>, <b>%</b> |
|
(<b>+</b> and <b>-</b> can be unary, preceding |
|
the first number in an expression, and <b>%</b> is |
|
the modulo operator), </li> |
|
<li> balanced <b>(</b> ... <b>)</b> |
|
parentheses nested to any level (see below), </li> |
|
<li> whitespace anywhere |
|
(except between digits comprising a number), </li> |
|
<li> One additional construction interpreted by <b>\eval{ }</b> |
|
is similar to (but not identical to) the |
|
<a href="http://wikipedia.org/wiki/Conditional_(programming)#As_a_ternary_operator" |
|
target="_top">?: conditional</a>, as follows. |
|
The expression <b>(i?v0:v1:v2:<i>etc</i>)</b>, usually |
|
parenthesized as illustrated, evaluates to <b>v0</b> |
|
if <b>i</b> evaluates to <b>0</b>, or evaluates to <b>v1</b> |
|
if <b>i</b> evaluates to <b>1</b>, etc. If <b>i < 0</b> |
|
then <b>v0</b> is used, and if <b>i</b> is too large, the last |
|
<b>v</b> is used. All components, <b>i</b> and all <b>v</b>'s, |
|
can themselves be expressions, even another |
|
<b>(i?v0:v1:v2:<i>etc</i>)</b>, which in this case must be |
|
parenthesized. The only situation where parentheses aren't |
|
required is when <b>i?v0:v1:v2:<i>etc</i></b> comprises |
|
your entire expression. |
|
For example, <br> <nobr> |
|
<b>\eval{1+2?10:11:12:13:14:15}</b> renders |
|
<a href="#preview"><img id="eval1" onclick="eqntext('eval1')" |
|
src="../cgi-bin/mimetex.cgi?\large\eval{1+2?10:11:12:13:14:15}" |
|
alt="" border=0 align=bottom></a></nobr></li> |
|
<li> and <u> most importantly, </u> |
|
the built-in variables<br> |
|
<b>fs</b> for current fontsize and<br> |
|
<b>unitlength</b> for unitlength<br> |
|
which provide the capability for useful constructions, |
|
as follows... </li> |
|
</ul> |
|
|
|
<p> All optional <b>[</b> <b>]</b> and mandatory |
|
<b>{</b> <b>}</b> numeric arguments for |
|
<a href="#rule">\rule[lift]{width}{height}</a>, |
|
<a href="#compose">\compose[offset]{ }{ }</a>, |
|
<a href="#raiserotate">\raisebox{height}{ }</a>, |
|
<a href="#raiserotate">\rotatebox{angle}{ }</a>, and |
|
<a href="#arrows">\longarrow[width]</a> |
|
can be expressions as described above, rather than just |
|
numeric constants. By using the <b>fs</b> variable, you can |
|
construct <a href="#newcommands">\newcommand</a> |
|
expressions that properly scale with font size. |
|
For example, the <b>\mapsto</b> symbol is not explicitly provided |
|
in any mimeTeX font, but is instead constructed by the |
|
embedded <a href="#newcommands">\newcommand</a><br> |
|
<nobr> <b> |
|
{ "\\mapsto", NULL, "{\\rule[fs/2]{1}{5+fs}\\hspace{-99}\\to}" },</b> |
|
</nobr><br> |
|
where \rule's [lift]=fs/2 and {height}=5+fs are scaled by |
|
font size to render symbols<br> |
|
|
|
<a href="#preview"><img id="eval2" onclick="eqntext('eval2')" |
|
src="../cgi-bin/mimetex.cgi?\small\text\begin{array}{rrl} |
|
\backslash tiny & fs=\tiny\eval{fs} & \tiny\mapsto \\ |
|
\backslash small & fs=\small\eval{fs} & \small\mapsto \\ |
|
\backslash normalsize & fs=\normal\eval{fs} & \normal\mapsto\\ |
|
\backslash large & fs=\large\eval{fs} & \large\mapsto \\ |
|
etc. & & |
|
\end{array}" alt="" border=0 align=middle></a><br> |
|
whose rendering automatically varies appropriately with font size. |
|
This kind of <a href="#newcommands">\newcommand</a> construction |
|
is the primary use intended for mimeTeX's expression evaluation feature. |
|
</p> |
|
|
|
<p> But mimeTeX also provides the <b>\eval{<i>expression</i>}</b> |
|
command to make the expression evaluation feature render |
|
"visible" results. It's not particularly useful, |
|
but an expression like <b>1+2+3+4+5=\eval{1+2+3+4+5}</b> |
|
renders |
|
<a href="#preview"><img id="eval2" onclick="eqntext('eval2')" |
|
src="../cgi-bin/mimetex.cgi?\small 1+2+3+4+5=\eval{1+2+3+4+5}" |
|
alt="" border=0 align="bottom"></a>. </p> |
|
|
|
<p> Finally, one little "gotcha" is mimeTeX's |
|
order of evaluation when interpreting expressions. |
|
Parentheses are respected as you'd expect. But within |
|
<b>(</b>...<b>)</b> parentheses, or in an |
|
unparenthesized expression, mimeTeX finds the first (reading |
|
from the left) operator, then iteratively evaluates the |
|
separate subexpressions to that operator's left and to its right, |
|
and then finally combines those two separate results. |
|
So an expression like <b>2*3+4</b> renders <b>14</b>, |
|
and you need to write <b>(2*3)+4</b> to get <b>10</b>. |
|
</p> |
|
|
|
|
|
<h3> <a name="magstep"> \magstep{ } and |
|
\magbox{ }{ }<font size=5>...</font></a> </h3> |
|
|
|
<p class="continue"> |
|
<b>\magstep{<i>magnification</i>}</b>, placed anywhere |
|
within an expression, magnifies the entire expression |
|
by an integer factor <b>1<=<i>magnification</i><=10</b> |
|
in both width and height. |
|
Each single pixel thus becomes a square box, <i>e.g.</i>, |
|
for <b><i>magnification</i>=2</b> each single pixel becomes |
|
a four-pixel square box with dimensions <b>2</b>-by-<b>2</b>. |
|
This compromises mimeTeX's anti-aliasing algorithm, |
|
and the resulting image is both hazy/blurry and jagged/staircased |
|
compared to an unmagnified image of the same expression. |
|
For example, at <b>\LARGE</b> size,<br> |
|
<nobr>   |
|
<b>f(x)=x^2</b> |
|
renders |
|
<a href="#preview"><img id="magbox1" onclick="eqntext('magbox1')" |
|
src="../cgi-bin/mimetex.cgi?\LARGE f(x)=x^2" |
|
alt="" border=0 align="absmiddle"></a> and </nobr><br> |
|
<nobr>   |
|
<b>\magstep{2} f(x)=x^2</b> |
|
renders |
|
<a href="#preview"><img id="magbox2" onclick="eqntext('magbox2')" |
|
src="../cgi-bin/mimetex.cgi?\LARGE\magstep{2} f(x)=x^2" |
|
alt="" border=0 align="absmiddle"></a> , whereas </nobr><br> |
|
at mimeTeX's largest "native" font size, <br> |
|
<nobr>   |
|
<b>\Huge f(x)=x^2</b> |
|
renders |
|
<a href="#preview"><img id="magbox3" onclick="eqntext('magbox3')" |
|
src="../cgi-bin/mimetex.cgi?\HUGE f(x)=x^2" |
|
alt="" border=0 align="absmiddle"></a> . </nobr><br> |
|
Nevertheless, if you still want to render images larger than |
|
mimeTeX's <b>\Huge</b> size, then <b>\magstep{<i>magnification</i>}</b> |
|
may render almost-acceptable results. </p> |
|
|
|
<p> To magnify just part of an expression, |
|
you can use <b>\magbox{<i>magnification</i>}{<i>expression</i>}</b>, |
|
which only magnifies each pixel within the enclosed |
|
<b>{<i>expression</i>}</b>, again |
|
by an integer factor <b>1<=<i>magnification</i><=10</b> |
|
in both width and height, and also adjusts the baseline accordingly. |
|
But <b>\magbox</b> is applied directly to mimeTeX's black-and-white |
|
bitmap <u><b><i> before anti-aliasing </i></b></u>. |
|
At the present time, this virtually completely defeats |
|
mimeTeX's anti-aliasing algorithm, and the resulting image |
|
exhibits even more pronounced jagged-line/staircase effects. |
|
For example, <br> |
|
<nobr>   |
|
<b>\LARGE f(x)={\magbox{2}{x}}^2</b> |
|
renders |
|
<a href="#preview"><img id="magbox5" onclick="eqntext('magbox5')" |
|
src="../cgi-bin/mimetex.cgi?\LARGE f(x)={\magbox{2}{x}}^2" |

<a href="#preview"><img id="messages1" onclick="eqntext('messages1')" |
|
src="../cgi-bin/mimetex.cgi?\normalsize\alpha\beta\gamma\delta" |
|
border=0 align=bottom></a>, but you mistakenly type |
|
<b>\alpha\bethe\gamma\delta</b> instead. |
|
Then the image rendered is |
|
<a href="#preview"><img id="messages2" onclick="eqntext('messages2')" |
|
src="../cgi-bin/mimetex.cgi?\normalsize\alpha\bethe\gamma\delta" |
|
border=0 align=bottom></a>, indicating the unrecognized |
|
<b>[\bethe?]</b> where you wanted to type <b>\beta</b> |
|
and hoped to see |
|
<a href="#preview"><img id="messages3" onclick="eqntext('messages3')" |
|
src="../cgi-bin/mimetex.cgi?\normalsize\bf\beta" |
|
border=0 align=bottom></a>. |
|
If your expression contains some unprintable character |
|
(meaning any character mimeTeX has no bitmap for), |
|
then just |
|
<a href="#preview"><img id="messages4" onclick="eqntext('messages4')" |
|
src="../cgi-bin/mimetex.cgi?\small\bf[?]" |
|
border=0 align=bottom></a> is displayed in the |
|
corresponding position. </p> |
|
|
|
<p> The preceding example illustrates a pretty trivial error. |
|
Any non-trivial errors in your expression are likely to |
|
go unrecognized and unreported by mimeTeX, and to render |
|
unexpected images. While checking your input expression |
|
for syntax errors, keep in mind the following points |
|
about mimeTeX's behavior: </p> |
|
<ul> |
|
<li> An unmatched left brace <b>{</b> is matched |
|
by mimeTeX with a "phantom" right brace <b>}</b> |
|
that's imagined to be at the end of your expression. </li> |
|
<li> Likewise, an unmatched <b>\left(</b>, |
|
or <b>\left\{</b> or <b>\left\</b><i>anything</i>, |
|
is matched by mimeTeX with a "phantom" <b>\right.</b> |
|
at the end of your expression. </li> |
|
<li> On the other hand, an unmatched right brace <b>}</b> |
|
is displayed in place, as if you had typed \rbrace. </li> |
|
<li> But an unmatched <b>\right\</b><i>anything</i> |
|
is interpreted as an abbreviation for <b>\</b>rightarrow |
|
followed by <b>\</b><i>anything</i>. For example, |
|
<b>\leff( abc \right) def</b> renders |
|
<a href="#preview"><img id="messages5" |
|
onclick="eqntext('messages5')" |
|
src="../cgi-bin/mimetex.cgi?\small\leff(abc\right)def" |
|
border=0 align=bottom></a>. </li> |
|
</ul> <!-- p class="continue"> |
