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
