方法详细资料

drawBar

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

"Draws" a bar at the given coordinates.

指定者:

drawBar 在类中 AbstractOutput

参数:

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

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.

参数:

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

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

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.

参数:

x - the x coordinate

y - the y coordinate

width - the width to be painted

height - the height to be painted

beginDraw

public void beginDraw(double width,
             double height)

从类复制的说明: AbstractOutput

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

指定者:

beginDraw 在类中 AbstractOutput

参数:

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

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

endDraw

public void endDraw()

从类复制的说明: AbstractOutput

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

指定者:

endDraw 在类中 AbstractOutput

drawText

public double drawText(java.lang.String text,
              double x,
              double y,
              double width)

从类复制的说明: AbstractOutput

Draw the specified text.

指定者:

drawText 在类中 AbstractOutput

参数:

text - text to draw

x - x position

y - y position

width - width of barcode (total)

返回:

the height of this text

drawText

public void drawText(java.lang.String leadChar,
            LabelLayout createMarginLayout)

指定者:

drawText 在类中 AbstractOutput
