Method Detail

drawBar

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

"Draws" a bar at the given coordinates.

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

beginDraw

public void beginDraw()

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

endDraw

public void endDraw(int width,
                    int height)

Balanced with startDraw() above, used for caching, output of epilogues (for SVG), etc.

Parameters:

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

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

drawText

public int drawText(String text,
                    LabelLayout labelLayout)
             throws OutputException

Description copied from interface: Output

Draw the specified text.

Parameters:

text - text to draw

labelLayout - the text layout calculator

Returns:

the height of this text

Throws:

OutputException

paintBackground

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

Paint the background the background colour, based on the height and the width.

Parameters:

x - the x coordinate

y - the y coordinate

width - the width to be painted

height - the height to be painted
