      gs - the canvas graphics state
      ctm - the coordinate transformation matrix at the time the image is rendered
      imageStream - the image stream object
      resourceName - the name of the image resource
      colorSpaceDictionary - the color space dictionary from resources which are associated with the image
      isInline - defines if the encountered image was inline
