<div class="markdown level1 summary"><p>Gets the frame image as a <a class="xref" href="GrapeCity.Documents.Imaging.GcBitmap.html">GcBitmap</a>.</p>
<p>Many GIF files use frames with transparent pixels where the previous frame
is partly visible. If you read multiple GIF frames you can improve the performance
dramatically by reading frames into the same <a class="xref" href="GrapeCity.Documents.Imaging.GcBitmap.html">GcBitmap</a> and passing
index of the previous frame in the additional contentFrameIndex parameter.</p>
