class="container-overview"> <div class="description"><p>This module deals with creating delimiters of various sizes. The TeXbook discusses these routines on page 441-442, in the "Another subroutine sets box x to a specified variable delimiter" paragraph.</p> <p>There are three main routines here. <code>makeSmallDelim</code> makes a delimiter in the normal font, but in either text, script, or scriptscript style. <code>makeLargeDelim</code> makes a delimiter in textstyle, but in one of the Size1, Size2, Size3, or Size4 fonts. <code>makeStackedDelim</code> makes a delimiter out of smaller pieces that are stacked on top of one another.</p> <p>The functions take a parameter <code>center</code>, which determines if the delimiter should be centered around the axis.</p> <p>Then, there are three exposed functions. <code>sizedDelim</code> makes a delimiter in one of the given sizes. This is used for things like <code>\bigl</code>. <code>customSizedDelim</code> makes a delimiter with a given total height+depth. It is called in places like <code>\sqrt</code>. <code>leftRightDelim</code> makes an appropriate delimiter which surrounds an expression of a given height an depth. It is used in <code>\left</code> and <code>\right</code>.</p></div> <div class='method'> <dl class="details"> <span class="tag-source"> <a href="core_delimiters.js.html#line1">Source</a> </span> </dl> </div> </div> <h3 class="subsection-title">Methods</h3> <div class='method private'> <h4 class="name" id=".makeCustomSizedDelim">makeCustomSizedDelim<span class="signature">(type<span class="signature-type">: string</span>, delim<span class="signature-type">: string</span>, height<span class="signature-type">: number</span>, center<span class="signature-type">: boolean</span>, context<span class="signature-type">: Context.Context</span>, classes<span class="signature-type">: Array.<string></span>)</span><span class="type-signature"></span><span class="type-signature"><span class="attrib">private</span><span class="attrib">static</span></span></h4> <div class="description"> <p>Make a delimiter of a given height+depth, with optional centering.
