+<h1>The GNU Implementation of FlatteningPathIterator</h1>
+
+<p><i><a href="http://www.dandelis.ch/people/brawer/">Sascha
+Brawer</a>, November 2003</i></p>
+
+<p>This document describes the GNU implementation of the class
+<code>java.awt.geom.FlatteningPathIterator</code>. It does
+<em>not</em> describe how a programmer should use this class; please
+refer to the generated API documentation for this purpose. Instead, it
+is intended for maintenance programmers who want to understand the
+implementation, for example because they want to extend the class or
+fix a bug.</p>
+
+
+<h2>Data Structures</h2>
+
+<p>The algorithm uses a stack. Its allocation is delayed to the time
+when the source path iterator actually returns the first curved
+segment (either <code>SEG_QUADTO</code> or <code>SEG_CUBICTO</code>).
+If the input path does not contain any curved segments, the value of
+the <code>stack</code> variable stays <code>null</code>. In this quite
+common case, the memory consumption is minimal.</p>
+
+<dl><dt><code>stack</code></dt><dd>The variable <code>stack</code> is
+a <code>double</code> array that holds the start, control and end
+points of individual sub-segments.</dd>
+
+<dt><code>recLevel</code></dt><dd>The variable <code>recLevel</code>
+holds how many recursive sub-divisions were needed to calculate a
+segment. The original curve has recursion level 0. For each
+sub-division, the corresponding recursion level is increased by
+one.</dd>
+
+<dt><code>stackSize</code></dt><dd>Finally, the variable
+<code>stackSize</code> indicates how many sub-segments are stored on
+the stack.</dd></dl>
+
+<h2>Algorithm</h2>
+
+<p>The implementation separately processes each segment that the
+base iterator returns.</p>
+
+<p>In the case of <code>SEG_CLOSE</code>,
+<code>SEG_MOVETO</code> and <code>SEG_LINETO</code> segments, the
+implementation simply hands the segment to the consumer, without actually
+doing anything.</p>
+
+<p>Any <code>SEG_QUADTO</code> and <code>SEG_CUBICTO</code> segments
+need to be flattened. Flattening is performed with a fixed-sized
+stack, holding the coordinates of subdivided segments. When the base
+iterator returns a <code>SEG_QUADTO</code> and
+<code>SEG_CUBICTO</code> segments, it is recursively flattened as
+follows:</p>
+
+<ol><li>Intialization: Allocate memory for the stack (unless a
+sufficiently large stack has been allocated previously). Push the
+original quadratic or cubic curve onto the stack. Mark that segment as
+having a <code>recLevel</code> of zero.</li>
+
+<li>If the stack is empty, flattening the segment is complete,
+and the next segment is fetched from the base iterator.</li>
+
+<li>If the stack is not empty, pop a curve segment from the
+stack.
+
+ <ul><li>If its <code>recLevel</code> exceeds the recursion limit,
+ hand the current segment to the consumer.</li>
+
+ <li>Calculate the squared flatness of the segment. If it smaller
+ than <code>flatnessSq</code>, hand the current segment to the
+ consumer.</li>
+
+ <li>Otherwise, split the segment in two halves. Push the right
+ half onto the stack. Then, push the left half onto the stack.
+ Continue with step two.</li></ul></li>
+</ol>
+
+<p>The implementation is slightly complicated by the fact that
+consumers <em>pull</em> the flattened segments from the
+<code>FlatteningPathIterator</code>. This means that we actually
+cannot &#x201c;hand the curent segment over to the consumer.&#x201d;
+But the algorithm is easier to understand if one assumes a
+<em>push</em> paradigm.</p>
+
+
+<h2>Example</h2>
+
+<p>The following example shows how a
+<code>FlatteningPathIterator</code> processes a
+<code>SEG_QUADTO</code> segment. It is (arbitrarily) assumed that the
+recursion limit was set to 2.</p>

+
+ <li>Currently, the curve in the stack would be approximated by one

+ Therefore, <code>stackSize</code> is set to 1.</li>
+
+ <li>This single straight line segment is approximating the original

+ splits. Therefore, <code>recLevel[0]</code> is set to

+
+Column A shows the state after the initialization step.</li>
+
+<li>The algorithm proceeds by taking the topmost curve segment

+ is called to calculate the squared flatness.</li>
+
+ <li>For the sake of argument, we assume that the squared flatness is
+ exceeding the threshold stored in <code>flatnessSq</code>. Thus, the
+ curve segment <i>S</i> &#x2013; <i>C</i> &#x2013; <i>E</i> gets
+ subdivided into a left and a right half, namely

+ <i>C<sub>r</sub></i> &#x2013; <i>E<sub>r</sub></i>. Both halves are

+
+ <br />&nbsp;<br />The left half starts at the same point

+ half and of the original curve are identical
+ (<i>E<sub>r</sub></i> = <i>E</i>). More interestingly, the left
+ half ends where the right half starts. Because
