The result of this function returns in a <code>u16</code> array, <SPAN class="argument">selectedPoints</SPAN>, which is the position number of the points in <code>strokes->points</code> that remain after resampling. The results also return in <SPAN class="argument">pSelectedPointNum</SPAN>, which is the number of points. In the array, the numbers are stored in ascending order. You must allocate a size of at least <SPAN class="argument">maxPointCount</SPAN> for <SPAN class="argument">selectedPoints</SPAN>.</P> 82<P>The <SPAN class="argument">buffer</SPAN> argument provides a pointer to the work area used for the resampling process. The work area requires <code>sizeof(int)*maxPointCount</code>. Allocate this beforehand.</P> 83<P>For details on the resampling algorithms and thresholds, see <A href="PRCResampleMethod.html"><CODE>PRCResampleMethod</CODE></A>.</P> 84<P>This function is not required for normal pattern recognition procedures.
