</p>
</div>
<div class="desc">
<h4>Description</h4>
<p>
This method may be invoked indirectly via the
<a href="rvgtext.html#tspan">tspan</a> method in <code>RVG::Text</code>.
</p>
<p>
Tspan objects are containers, so this method yields to a block if one is present. The only objects that a tspan can contain are other tspans. Styles
defined on a tspan propagate to any tspans contained within it.
</p>
<h4>Arguments</h4>
<p>All arguments are optional.</p>
<dl>
<dt>text</dt>
<dd>
A string. If present, this string is drawn at the current text position. By default the string is positioned with the lower-left corner of the first
glyph at the current text position. Use the
<a href="rvgtext.html#text_anchor">:text_anchor</a> style to override this behavior. After the string is rendered, the current text position is moved
to the end of the string.
</dd>
<dt>x, y</dt>
<dd>Specify a new current text position within the current user coordinate system.</dd>
</dl>
<h4>Examples</h4>
<p>
<a href="javascript:popup('tspan01.rb.html')"><img src="ex/tspan01.gif" title="Click to see the example script" alt="tspan example" /></a>

<em>self</em>
</p>
</div>
<div class="desc">
<h4>Description</h4>
<p>
The <span class="arg">dx</span> and <span class="arg">dy</span> arguments are added to the the current text position to form a new current text
position. Yields to a block if one is present.
</p>
<h4>Arguments</h4>
<dl>
<dt>dx, dy</dt>
<dd>The distance, in the user coordinate system, to be added to the current text position.</dd>

<a href="javascript:popup('tspan02.rb.html')"><img src="ex/tspan02.gif" title="Click to see the example script" alt="tspan example 2" /></a>

<p><span class="arg">tspan</span>.rotate(<span class="arg">degrees</span>) [ <span class="arg">{ |self| ...}</span> ] -> <em>self</em></p>

<div class="desc">
<h4>Description</h4>
<p>Rotates the text about the current text position by the specified number of <span class="arg">degrees</span>. Yields to a block if one is present.</p>
<h4>Arguments</h4>
<dl>
<dt>degrees</dt>
<dd>The amount of rotation</dd>

<a href="javascript:popup('tspan03.rb.html')"><img src="ex/tspan03.gif" title="Click to see the example script" alt="tspan example 3" /></a>

</p>
</div>
<div class="desc">
<h4>Description</h4>
<p>
Calls <a href="#new">RVG::Tspan.new</a> to construct a tspan and adds it to the tspan. Yields to a block if one is present, passing the new tspan as an
argument. Styles defined on the container tspan propagate to the contained tspan.
</p>
<h4>Arguments</h4>
<dl>
<dt>string</dt>
<dd>A text string.</dd>
<dt>x, y</dt>
<dd>A new initial text position</dd>
</dl>
<h4>Returns</h4>
<p>The new tspan, so other <code>RVG::Tspan</code> methods can be chained to it.</p>
