  14
  15 The libswscale library performs highly optimized image scaling and
  16 colorspace and pixel format conversion operations.
  17
  18 Specifically, this library performs the following conversions:
  19
  20 @itemize
  21 @item
  22 @emph{Rescaling}: is the process of changing the video size. Several
  23 rescaling options and algorithms are available. This is usually a
  24 lossy process.
  25
  26 @item
  27 @emph{Pixel format conversion}: is the process of converting the image
  28 format and colorspace of the image, for example from planar YUV420P to
  29 RGB24 packed. It also handles packing conversion, that is converts
  30 from packed layout (all pixels belonging to distinct planes
  31 interleaved in the same buffer), to planar layout (all samples
  32 belonging to the same plane stored in a dedicated buffer or "plane").
  33
  34 This is usually a lossy process in case the source and destination
  35 colorspaces differ.
