The ICompressionSettings interface provides images, video, and audio compression settings. For video and audio, you can set bitrate or quality in percents. For images, you can set quality in percents or IQ_LOSSLESS, which allows the compression of PNG images without loss in quality,
This interface can be obtained using the ISettings.Compression property.
