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