      Returns the transform.
      Returns:
      the current transformation matrix
    • checkTransform

      public boolean checkTransform(AffineTransform tf)

      Returns:
      true if the new transform is different then the current transform
    • concatMatrix

      public void concatMatrix(AffineTransform transform)
      Concats the given transformation matrix with the current one.
      Parameters:
      transform - The new transformation matrix
    • useLineCap

      public boolean useLineCap(int value)
      Establishes the specified line cap.
      Parameters:

    • useLineJoin

      public boolean useLineJoin(int value)
      Establishes the specified line join.
      Parameters:
      value - line join (0, 1 or 2) as defined by the setlinejoin command
