+<p>The libswscale library performs highly optimized image scaling and
+colorspace and pixel format conversion operations.
+</p>
+<p>Specifically, this library performs the following conversions:
+</p>
+<ul>
+<li> <em>Rescaling</em>: is the process of changing the video size. Several
+rescaling options and algorithms are available. This is usually a
+lossy process.
+
+</li><li> <em>Pixel format conversion</em>: is the process of converting the image
+format and colorspace of the image, for example from planar YUV420P to
+RGB24 packed. It also handles packing conversion, that is converts
+from packed layout (all pixels belonging to distinct planes
+interleaved in the same buffer), to planar layout (all samples
+belonging to the same plane stored in a dedicated buffer or &quot;plane&quot;).
+
+<p>This is usually a lossy process in case the source and destination
+colorspaces differ.
+</p></li></ul>
