| @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. |
