@chapter Description

@c man begin DESCRIPTION
|
|
|
|
The libswscale library performs highly optimized image scaling and
|
|
colorspace and pixel format conversion operations.
|
|
|
|
Specifically, this library performs the following conversions:
|
|
|
|
@itemize
|
|
@item
|
|
@emph{Rescaling}: is the process of changing the video size. Several
|
|
rescaling options and algorithms are available. This is usually a
|
|
lossy process.
|
|
|
|
@item
|
|
@emph{Pixel format conversion}: 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 "plane").
|
|
|
|
This is usually a lossy process in case the source and destination
|
|
colorspaces differ.
