Method Detail

beginDraw

public void beginDraw()

Description copied from interface: Output

Sets up the drawing environment. Called before drawing starts. Matched with call to endDraw() at the end. This allows for caching as needed.

endDraw

public void endDraw(int width,
                    int height)

From AbstractOutput - finished up the EPS output.

Parameters:

width - The output width (in pixels) of the barcode

height - The output height (in pixels) of the barcode.

drawBar

public int drawBar(int x,
                   int y,
                   int width,
                   int height,
                   boolean paintWithForegroundColor)

From AbstractOutput - outputs the correct rectangle to the EPS output.

Parameters:

x - the x coordinate

y - the y coordinate

width - the width

height - the height

paintWithForegroundColor - if true, use the foreground color, otherwise use the background color

Returns:

the width of the bar drawn

drawBarEPS

public double drawBarEPS(double x,
                         double y,
                         double width,
                         double height,
                         boolean paintWithForegroundColor)

From AbstractOutput - outputs the correct rectangle to the EPS output.

Parameters:

x - the x coordinate

y - the y coordinate

width - the width

height - the height

paintWithForegroundColor - if true, use the foreground color, otherwise use the background color

drawText

public int drawText(java.lang.String text,

Overrides:

toggleDrawingColor in class AbstractOutput

paintBackground

public void paintBackground(int x,
                            int y,
                            int width,
