<p>Always call this function after <a href="ft2-glyph_stroker.html#FT_Stroker_GetBorderCounts">FT_Stroker_GetBorderCounts</a> to get sure that there is enough room in your <a href="ft2-outline_processing.html#FT_Outline">FT_Outline</a> object to receive all new data.</p>
<p>When an outline, or a sub-path, is ‘closed’, the stroker generates two independent ‘border’ outlines, named ‘left’ and ‘right’</p>
<p>When the outline, or a sub-path, is ‘opened’, the stroker merges the ‘border’ outlines with caps. The ‘left’ border receives all points, while the ‘right’ border becomes empty.</p>
<p>Use the function <a href="ft2-glyph_stroker.html#FT_Stroker_Export">FT_Stroker_Export</a> instead if you want to retrieve all borders at once.</p>
