16 The libswscale library performs highly optimized image scaling and
17 colorspace and pixel format conversion operations.
19 Specifically, this library performs the following conversions:
23 @emph{Rescaling}: is the process of changing the video size. Several
24 rescaling options and algorithms are available. This is usually a
28 @emph{Pixel format conversion}: is the process of converting the image
29 format and colorspace of the image, for example from planar YUV420P to
30 RGB24 packed. It also handles packing conversion, that is converts
31 from packed layout (all pixels belonging to distinct planes
32 interleaved in the same buffer), to planar layout (all samples
33 belonging to the same plane stored in a dedicated buffer or "plane").
35 This is usually a lossy process in case the source and destination
