Changes the current image index in the case of multi-image files.
When working with multi-image files all graphic importer commands apply to the "current image". The current image is identified by its index. The image index ranges from 1 to the total number of images in the file. The default image index is 1.
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 imageIndex specifies the image index.
Note: An image index value of zero (0) is usually equivalent to one (1), unless some importers treat the zero value in a special way.
