| =head1 NAME | |
| libswscale - video scaling and pixel format conversion library | |
| =head1 DESCRIPTION | |
| The libswscale library performs highly optimized image scaling and | |
| colorspace and pixel format conversion operations. | |
| Specifically, this library performs the following conversions: | |
| =over 4 | |
| =item * | |
| I<Rescaling>: is the process of changing the video size. Several | |
| rescaling options and algorithms are available. This is usually a | |
| lossy process. | |
| =item * | |
| I<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. | |
