+
+<p>A 9-patch is a method of rendering a texture so that it can be
+stretched to cover an area of any size without becoming distorted.
+This is achieved by dividing up the sprite into nine regions:
+</p>
+<ul>
+<li> the center, which can be stretched or tiled horizontally and vertically
+</li><li> the four corners, which are never stretched or tiled
+</li><li> the left and right sides, which can be stretched or tiled vertically
+</li><li> the top and bottom sides, which can be stretched or tiled horizontally
+</li></ul>
+
+<p>The most common application of this technique is for graphical user
+interface widgets like buttons and dialog boxes which are often
+dynamically resizable. By using a 9-patch, they can be rendered at
+any size without scaling artifacts.
+</p>

+<dt id="index-draw_002dnine_002dpatch">Procedure: <strong>draw-nine-patch</strong> <em>texture rect [#:margin 0] [#:top-margin margin] [#:bottom-margin margin] [#:left-margin margin] [#:right-margin margin] [#:mode stretch] [#:origin] [#:scale] [#:rotation] [#:blend-mode] [#:tint white]</em></dt>
+<dd>
+<p>Draw a 9-patch over the area <var>rect</var> using <var>texture</var> whose
+stretchable/tileable patches are defined by the given margin
+measurements. The corners are never stretched/tiled, the left and
+right edges will be stretched/tiled vertically, the top and bottom
+edges may be stretched/tiled horizontally, and the center may be
+stretched/tiled in both directions.
+</p>
+<p><var>mode</var> may be either <code>stretch</code> (the default) or <code>tile</code>.
+</p>
+<p><var>margin</var> specifies the margin size for all sides of the 9-patch.
+To make margins of differing sizes, the <var>top-margin</var>,
+<var>bottom-margin</var>, <var>left-margin</var>, and <var>right-margin</var>
+arguments may be used.
+</p>
+<p>Refer to <code>draw-sprite</code> (see <a href="Sprites.html">Sprites</a>) for information about
+the other arguments as they are the same.
