Get the current frame of a multi-image image
The graphics importer instance is specified by importerRef. If importerRef is not a reference to a valid graphics importer instance, error qpx_paramErr is returned.
Parameter frameIndex receives the current frame index. The frame index ranges from 1 to the total number of frames in the image. The default frame index is 1.
NOTE When working with multi-frame images, all importer commands apply to the "current" frame.
NOTE A frame index value of zero (0) is usually equivalent to one (1), unless the importer treat the zero value in a special way (some do).
