  • Method Details

    • getMode

      public ModeEnum getMode()
      Description copied from interface: JRCommonElement
      Returns the element transparency mode. The default value depends on the type of the report element. Graphic elements like rectangles and lines are opaque by default, but the images are transparent. Both static texts and text fields are transparent by default, and so are the subreport elements.

      getMode in class JRBaseElement
