Some file formats may contain multiple frames in a single file. QPix currently supports the following multi-frame file formats:

This command returns the number of frames contained in the image (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 numFrames receives the number of frames.

Note: Individual frames in a multi-frame image may have different characteristics (width and height, depth, etc).
