Returns the number of images in a multi-image container.
Some file formats may contain multiple images in a single file. QuickTime 4 currently supports the following multi-image file formats:
This command returns the number of images contained in the image container (file, URL, or BLOB) that is associated with the importer instance specified by importerRef. If importerRef is not a reference to a valid graphics importer instance, error qpx_paramErr is returned.
Parameter numImages receives the number of images.
Note: Individual images in a multi-image file may have different characteristics (width and height, depth, etc).
