Method from org.apache.pdfbox.filter.FilterManager Detail:
 public  void addFilter(COSName filterName,
    Filter filter) {
        filters.put( filterName, filter );
}
This will add an available filter.
 public Filter getFilter(COSName filterName) throws IOException {
        Filter filter = (Filter)filters.get( filterName );
        if( filter == null )
        {
            throw new IOException( "Unknown stream filter:" + filterName );
        }
        return filter;
}
This will get a filter by name.
 public Filter getFilter(String filterName) throws IOException {
        return getFilter( COSName.getPDFName( filterName ) );
}
This will get a filter by name.
 public Collection<Filter> getFilters() {
        return filters.values();
}
This will get all of the filters that are available in the system.
