+
MimeTeX doesn't need intermediate dvi-to-gif conversion, and it doesn't create separate gif files for each converted expression. (But you can enable image caching with mimeTeX's   -DCACHEPATH=\"path/\"   - compile option.)

- -

-mimeTeX plugins...

-

There's no inherent need to repeatedly write the cumbersome - <img> tag illustrated above. You can write your own custom tags, - or write a wrapper script around mimeTeX to simplify the - notation.

- -

For example, - the following javascript snippet (based on - mathtran's - mathtran_img.js) lets you just write   - <img alt="mimetex:c=\sqrt{a^2+b^2}">   - wherever you want to see  

- 
   <script type="text/javascript">
-   <!--
-   // Create a namespace to hold variables and functions
-   mimetex = new Object();
-   // Change this to use your server
-   mimetex.imgSrc = "http://www.yourdomain.com/cgi-bin/mimetex.cgi?";
-   // Transform the whole document: add src to each img with
-   // alt text starting with "mimetex:", unless img already has a src.
-   mimetex.init = function () {
-       if (! document.getElementsByTagName) return;
-       var objs = document.getElementsByTagName("img");
-       var len  = objs.length;
-       for (i=0; i<len; i++) {
-          var img = objs[i];
-          if (img.alt.substring(0,8) == 'mimetex:')
-             if (!img.src) {
-                var tex_src = img.alt.substring(8);
-                img.src = mimetex.imgSrc + encodeURIComponent(tex_src);
-                // Append TEX to the class of the IMG.
-                img.className +=' tex'; }
-          }
-       mimetex.hideElementById("mimetex.error"); }
-   // Utility function
-   mimetex.hideElementById = function (id) {
-       var obj = document.getElementById(id);
-       if (obj) obj.style.display = 'none'; }
-   // resolve a cross-browser issue (see CBS events)
-   mimetex.addEvent = function (obj, evType, fn, useCapture) {
-       if (obj.addEventListener) { //For Mozilla.
-           obj.addEventListener(evType, fn, useCapture);
-           return true; }
-       else if (obj.attachEvent) { //For Internet Explorer.
-           var r = obj.attachEvent("on"+evType, fn);
-           return r; }
-       }
-   // Initialize after entire document is loaded
-   mimetex.addEvent(window, 'load', mimetex.init, false);
-   -->
-   </script>
- -

- Bulletin boards, wikis, etc, can also incorporate mimeTeX images - with short scripts. For example, if you're using - phpBB2, then - Jameson - contributed the following typical one-line mod that lets you write - [tex] c=\sqrt{a^2+b^2} [/tex] to obtain the - same  image illustrated above 

- 
   #--------[open]-----------------------------------------------------
-     /includes/bbcode.php
-   #--------[find]-----------------------------------------------------
-     // Remove our padding from the string..
-   #--------[before, add]----------------------------------------------
-     $text = preg_replace('/\[tex\](.*?)\[\/tex\]/ie',
-     "'<img src=\"/cgi-bin/mimetex.cgi?'.rawurlencode('$1').'\" align=\"middle\" />'",
-     $text);
-

If you're using - phpBB3, - then no mod is even needed. - Just click Postings from the Administrator Control Panel, - and add the custom BBCode [tex]{TEXT}[/tex]   - with the HTML replacement - <img src="/cgi-bin/mimetex.cgi?{TEXT}" align=middle>

- -

Similarly, PmWiki also has a - - mimeTeX plugin that lets you just write - {$ f(x)=\int_{-\infty}^xe^{-t^2}dt $} - to obtain that same image.   Several other packages - also have similar mimeTeX plugins:

-
- - - - - - - - - - - - - - - - - - - -
 Package      Plugin  
- - PmWiki   - mimeTeX plugin
- - Wikimedia   - - "mimeTeX alternative"
- PunBB   - mimeTeX plugin
- - Movable Type   mimeTeX plugin
- WordPress   - - mimeTeX plugin
- -

Please note: If you're writing your own plugin for mimeTeX, - please don't write php code using system( ), or any other - shell escape mechanism, just to cache images. Use mimeTeX's -   -DCACHEPATH=\"path/\"   - compile option instead. - system( ) 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 system( ) - 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.

- -

-Vertical alignment...

-

An image like - - doesn't look as good as the same image - - that's vertically aligned with your surrounding text. - Along with several standard - - HTTP header fields, mimeTeX also emits a special -   Vertical-Align: –nn   - header, where –nn is the number of pixels - (usually negative as illustrated) needed for a -   style="Vertical-Align: –nn px" -   attribute in the <img> tag used to - render your expression.

- -

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

- 
   <?php
-   $mimetexurl = "http://www.yourdomain.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";
-      }
-   ?>
- -

Now you can write   - <?php mimetextag('\frac12\left(a^2+b^2\right)'); ?> - wherever you want to see - - correctly aligned. - 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.

- -

If you're using mimeTeX's -   -DCACHEPATH=\"path/\"   - compile option, prefix your - path/ with a leading % and write   - -DCACHEPATH=\"%path/\"   instead. - That leading % won't become part of your cache - directory's path/, 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.

+ compile option.) +   And there's no inherent need to repeatedly write the + cumbersome <img> tag illustrated above. + You can write your own + wrapper scripts, + discussed below, around mimeTeX to simplify the notation.

    \eval{ }...

    + +

    mimeTeX can evaluate arithmetic expressions, + which is a feature intended primarily for use in + \newcommand's discussed above. + Expressions can be built up from the following elements

    +
      +
    • digits   0-9 +   and numbers composed of uninterrupted (no whitespace) + sequences of digits,
      • +
    • binary operators   + +, -, *, /, % +   (+ and - can be unary, preceding + the first number in an expression, and % is + the modulo operator),
      • +
    • balanced   ( ... ) +   parentheses nested to any level (see below),
      • +
    • whitespace anywhere + (except between digits comprising a number),
      • +
    • One additional construction interpreted by \eval{ } + is similar to (but not identical to) the + ?: conditional, as follows. + The expression (i?v0:v1:v2:etc), usually + parenthesized as illustrated, evaluates to v0 + if i evaluates to 0, or evaluates to v1 + if i evaluates to 1, etc. If i < 0 + then v0 is used, and if i is too large, the last + v is used. All components, i and all v's, + can themselves be expressions, even another + (i?v0:v1:v2:etc), which in this case must be + parenthesized. The only situation where parentheses aren't + required is when i?v0:v1:v2:etc comprises + your entire expression. + For example,
            + \eval{1+2?10:11:12:13:14:15} renders +
      • +
    • and  most importantly,  + the built-in variables
      +       fs for current fontsize and
      +       unitlength for unitlength
      + which provide the capability for useful constructions, + as follows...
      • +
    + +

    All optional [ ] and mandatory + { } numeric arguments for   + \rule[lift]{width}{height},   + \compose[offset]{ }{ },   + \raisebox{height}{ },   + \rotatebox{angle}{ },   and   + \longarrow[width]   + can be expressions as described above, rather than just + numeric constants. By using the fs variable, you can + construct \newcommand + expressions that properly scale with font size. + For example, the \mapsto symbol is not explicitly provided + in any mimeTeX font, but is instead constructed by the + embedded \newcommand
    +       + { "\\mapsto", NULL, "{\\rule[fs/2]{1}{5+fs}\\hspace{-99}\\to}" }, +
    + where \rule's [lift]=fs/2 and {height}=5+fs are scaled by + font size to render symbols
    +   +
    + whose rendering automatically varies appropriately with font size. + This kind of \newcommand construction + is the primary use intended for mimeTeX's expression evaluation feature. +

    + +

    But mimeTeX also provides the \eval{expression} + command to make the expression evaluation feature render + "visible" results. It's not particularly useful, + but an expression like   1+2+3+4+5=\eval{1+2+3+4+5}   + renders   + .

    + +

    Finally, one little "gotcha" is mimeTeX's + order of evaluation when interpreting expressions. + Parentheses are respected as you'd expect. But within +   (...)   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 2*3+4 renders 14, + and you need to write (2*3)+4 to get 10. +

    + + +

    \magstep{ }   and   + \magbox{ }{ }...

    + +

    +  \magstep{magnification}, placed anywhere + within an expression, magnifies the entire expression + by an integer factor 1<=magnification<=10 + in both width and height. + Each single pixel thus becomes a square box, e.g., + for magnification=2 each single pixel becomes + a four-pixel square box with dimensions 2-by-2. + 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 \LARGE size,
    +         + f(x)=x^2   + renders   +   and
    +         + \magstep{2} f(x)=x^2   + renders   +  ,   whereas
    + at mimeTeX's largest "native" font size,
    +         + \Huge f(x)=x^2   + renders   +  .
    + Nevertheless, if you still want to render images larger than + mimeTeX's \Huge size, then \magstep{magnification} + may render almost-acceptable results.

    + +

    To magnify just part of an expression, + you can use \magbox{magnification}{expression}, + which only magnifies each pixel within the enclosed + {expression}, again + by an integer factor 1<=magnification<=10 + in both width and height, and also adjusts the baseline accordingly. + But \magbox is applied directly to mimeTeX's black-and-white + bitmap  before anti-aliasing . + 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,
    +         + \LARGE f(x)={\magbox{2}{x}}^2   + renders   + .

    mimeTeX Errors...

    + +

    Any (La)TeX error is typically also a mimeTeX error. + However, mimeTeX has no command line interface or + .log file for reporting errors. Its only + communication with you is through the mimeTeX image + rendered by your browser. So error messages are embedded + in that image whenever feasible. For example, + suppose you want to see + , but you mistakenly type +   \alpha\bethe\gamma\delta   instead. + Then the image rendered is + , indicating the unrecognized + [\bethe?] where you wanted to type   \beta   + and hoped to see + . + If your expression contains some unprintable character + (meaning any character mimeTeX has no bitmap for), + then just   +   is displayed in the + corresponding position.

    + +

    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:

    +
      +
    • An unmatched left brace   {   is matched + by mimeTeX with a "phantom" right brace   }   + that's imagined to be at the end of your expression.
      • +
    • Likewise, an unmatched   \left(,   + or \left\{   or \left\anything,   + is matched by mimeTeX with a "phantom"   \right. +   at the end of your expression.
      • +
    • On the other hand, an unmatched right brace   } +   is displayed in place, as if you had typed \rbrace.
      • +
    • But an unmatched   \right\anything   + is interpreted as an abbreviation for \rightarrow + followed by \anything. For example,   + \leff( abc \right) def   renders   + .

You'll need to compile your own version from source. + can't emit the long lines needed to display mimeTeX's larger font sizes. + gftype.zip contains a statically linked linux + executable modified to emit the necessary long lines. + It may or may not run on your intel linux machine. + If not, you'll need to compile your own version from source. The following instructions are for Unix/Linux:
            First, download both - + web-7.5.3.tar.gz and - web2c-7.5.3.tar.gz, - or more recent versions. Then   untar   them both, + + web2c-7.5.3.tar.gz + (note: these files are no longer + explicitly archived by ctan, having been superceded + by texlive sources, so the preceding two links + point to copies kept on my site, www.forkosh.com). + Then   untar   both gzipped tar files,   cd web2c-7.5.3/   and run   ./configure   and   make   in the usual way (make may fail before completion if you don't have all needed fonts installed, but it will create and compile gftype.c before failing). Now edit -   texk/web2c/gftype.c  and notice two lines very near the top - that   #define maxrow (79)   and similarly for maxcol. - Change both 79's to 1024, and then re-run make. The new   - texk/web2c/gftype   executable image can emit the long - lines needed for mimeTeX's larger font sizes.
