BARS
(package private) static byte[][] BARS
The bars to generate the code.
CHARS
(package private) static String CHARS
The index chars to BARS
.

Barcode39
public Barcode39()
Creates a new Barcode39.
createAwtImage
public java.awt.Image createAwtImage(Color foreground,
Color background)
Creates a java.awt.Image
. This image only
contains the bars without any text.
- createAwtImage in interface Barcode
foreground
- the color of the barsbackground
- the color of the background
getBarcodeSize
public Rectangle getBarcodeSize()
Gets the maximum area that the barcode and the text, if
any, will occupy. The lower left corner is always (0, 0).
- getBarcodeSize in interface Barcode
- the size the barcode occupies.
getBarsCode39
public static byte[] getBarsCode39(String text)
Creates the bars.
text
- the text to create the bars. This text does not include the start and
stop characters
getChecksum
(package private) static char getChecksum(String text)
Calculates the checksum.
getCode39Ex
public static String getCode39Ex(String text)
Converts the extended text into a normal, escaped text,
ready to generate bars.
placeBarcode
public Rectangle placeBarcode(PdfContentByte cb,
Color barColor,
Color textColor)
Places the barcode in a
PdfContentByte
. The
barcode is always placed at coodinates (0, 0). Use the
translation matrix to move it elsewhere.
The bars and text are written in the following colors:
barColor | textColor | Result |
---|
null | null | bars and text painted with current fill color |
barColor | null | bars and text painted with barColor |
null | textColor | bars painted with current color text painted with textColor |
