Getting Information About Compressed Data
This section describes the functions that enable your application to collect information about compressed images and images that are about to be compressed. Your application may use some of these functions in preparation for compressing or decompressing an image or sequence.You can use the
GetCompressionTimefunction to determine how long it will take for a compressor to compress a specified image. Similarly, you can use theGetMaxCompressionSizefunction to find out how large the compressed image may be after the compression operation.You can use the
GetCompressedImageSizeto determine the size of a compressed image that does not have a complete image description.The
GetSimilarityfunction allows you to determine how similar two images are. This information is useful when you are performing temporal compression on an image sequence.
