Image Compression Manager Functions

The following sections describe the functions that the Image Compression Manager provides to application programs. This section is divided into the following topics:

"Getting Information About Compressor Components" describes the Image Compression Manager functions that allow applications to gather information about the manager and installed compressor components
"Getting Information About Compressed Data" describes the functions that allow applications to obtain information about compressed images
"Working With Images" defines the functions that applications can use to compress and decompress single-frame images that are stored in pixel maps
"Working With Pictures and PICT Files" describes the functions that applications can use to compress and decompress single-frame images that are stored as pictures or picture files (PICT files)
"Making Thumbnail Pictures" defines the functions that create and manipulate thumbnail images
"Working With Sequences" describes the functions that allow applications to compress and decompress sequences of images
"Changing Sequence-Compression Parameters" discusses the functions that your application can use to manipulate many of the parameters that govern sequence- compression operations
"Constraining Compressed Data" describes the functions and a data structure that allow your application to communicate information to compressors that can constrain compressed data to a specific data rate
"Changing Sequence-Decompression Parameters" discusses the functions that your application can use to manipulate many of the parameters that govern sequence-decompression operations
"Working With the StdPix Function" describes the functions that work with the StdPix function to allow your application to have access to compressed image data as it is displayed
"Aligning Windows" describes the functions that your application can use to position individual windows along optimal alignment grids
"Working With Graphics Devices and Graphics Worlds" discusses the functions that let you select graphics devices and specify graphics worlds for use in compression and decompression operations
