    Modifier and Type Method Description
    boolean canProcess​(java.lang.String extension)
    this method returns, if the plugin is able to process files with a given extension
    java.util.Vector<Node> getDetectedNodes()
    this method is called by the GMAF to receive the results of this plugin and to fuse it into the MMFG
    static java.awt.Dimension getImageDimension​(java.io.File imgFile)
    Gets image dimensions for given file
    boolean isGeneralPlugin()
    if this plugin contains overall metadata, e.g.
    void process​(java.net.URL url, java.io.File f, byte[] bytes, MMFG fv)
    this method is called by the GMAF framework, when a new asset has to be processed
    boolean providesRecoursiveData()
    this method should indicate, if it returns recursive data, which are then re-processed within the GMAF framework
