    • Method Detail

      • getTransform

        public AffineTransform getTransform()
        Returns the transform.
        Returns:
        the current transformation matrix

      • checkTransform

        public boolean checkTransform​(AffineTransform tf)
        Check the current transform. The transform for the current state is the combination of all transforms in the current state. The parameter is compared against this current transform.
        Parameters:
        tf - the transform the check against
        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:
        value - line cap (0, 1 or 2) as defined by the setlinecap command
        Returns:
        true if the line cap changed compared to the previous setting

      • 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
        Returns:
        true if the line join changed compared to the previous setting

      • useMiterLimit

        public boolean useMiterLimit​(float value)
        Establishes the specified miter limit.
        Parameters:
        value - the miter limit as defined by the setmiterlimit command
        Returns:
        true if the miter limit changed compared to the previous setting

      • useLineWidth

        public boolean useLineWidth​(double value)
        Establishes the specified line width.
        Parameters:
        value - line width as defined by the setlinewidth command
        Returns:
        true if the line width changed compared to the previous setting

      • useDash

        public boolean useDash​(String pattern)
        Establishes the specified dash.
        Parameters:
