Class Barcode128

java.lang.Object

totalcross.barcode.Barcode

totalcross.barcode.Barcode128

public class Barcode128
extends Barcode

Implements the code 128 and UCC/EAN-128. Other symbologies are allowed in raw mode.

The code types allowed are:

• CODE128 - plain barcode 128.
• CODE128_UCC - support for UCC/EAN-128.
• CODE128_RAW - raw mode. The code attribute has the actual codes from 0 to 105 followed by '\uffff' and the human readable text.

The default parameters are:

 x = 1f;
 font = new Font("Helvetica",Font.PLAIN,20));
 textAlignment = ALIGN_CENTER;
 codeType = CODE128;
 transparent = true;
 shotText = true
 quietZone = true;
 quietZoneX = 10;

Constructor Detail

Barcode128

public Barcode128()

Creates new Barcode128

Method Detail

getBarcodeWidth

public int getBarcodeWidth()

Gets the maximum width that the barcode will occupy. The lower left corner is always (0, 0).

Specified by:

getBarcodeWidth in class Barcode

Returns:

the size the barcode occupies.

getBarsCode128Raw

public static byte[] getBarsCode128Raw(java.lang.String text)

Generates the bars. The input has the actual barcodes, not the human readable text.

Parameters:

text - the barcode

Returns:

the bars

getRawText

public static java.lang.String getRawText(java.lang.String text,
                                          boolean ucc)

Converts the human readable text to the characters needed to create a barcode. Some optimization is done to get the shortest code.

Parameters:

text - the text to convert

ucc - true if it is an UCC/EAN-128. In this case the character FNC1 is added

Returns:

the code ready to be fed to getBarsCode128Raw()

placeBarcode

public void placeBarcode(Image i,
                         int barColor,
                         int textColor)

Places the barcode in a BufferedImage. The 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
barColor	textColor	bars painted with barColor text painted with textColor

Specified by:

placeBarcode in class Barcode

Parameters:

i - the Image where the barcode will be placed

barColor - the color of the bars. It can be -1

textColor - the color of the text. It can be -1
