Returns container value or error.
DescriptionCompresses a container value.
Compression is not recommended for file formats which are normally compressed already. This includes PDF, various image formats like PNG and JPEG, video and audio files as well as zip archives.
Compression works very well for text files.
It is recommended to check with Container.GetTotalSize to see if compressed data is smaller. If you compress an already compressed container, the result may be bigger due to the archive header.
Compressed containers can be detected by looking if the type list returned by Container.GetTypes contains an item named ZLIB. You can use Container.GetTypeSize to query the size of compressed data alone.
Not recommended for bigger file sizes. Compression may take long enough that user doesn't like to wait. e.g. 20 seconds for 300 MB.
