Working With Pictures and PICT Files
This section describes the functions that let your application compress and decompress single-frame images stored as pictures and PICT files. See "Working With Images," which begins on page 3-68, for information on compressing and manipulating single-frame images stored as pixel map structures. See "Working With Sequences," which begins on page 3-110, for information on compressing and decompressing sequences of images.As with image compression, the Image Compression Manager provides two sets of functions for working with compressed pictures. If you do not need to control the compression parameters, use the
CompressPictureorCompressPictureFilefunctions. If you need more control over the operation, use theFCompressPictureorFCompressPictureFilefunctions.The Image Compression Manager automatically expands compressed pictures when you display them. Use the
DrawPictureFilefunction to display the contents of a picture file. If you want to alter the spatial characteristics of the image, use theDrawTrimmedPictureorDrawTrimmedPictureFilefunctions.You can work with an image's control information by calling the
GetPictureFileHeaderfunction.
