Barcode128 (TotalCrossSDK 7.2.1 API)

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;
 
```

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
