Java Code 128 Image Setting Common Properties and Uses

      Code128 barcode = new Code128();

Adjust Code 128 Image Positon

Code 128 image position can be set with rotate and bar alignment:

      //Code 128 generated in Java with 0, 90, 180, 270 angles b y rotating it, default is 0 (IBarcode.ROTATE_0);
        Valid choices are 0 (IBarcode.ROTATE_0); 1 (IBarcode.ROTATE_90); 2 (IBarcode.ROTATE_180); 
        3 (IBarcode.ROTATE_270);
      barcode.setroatte(1 (IBarcode.ROTATE_90));
//Barcode horizontal alignment inside Code 128 can be set among with 0: left, 1: center, 2: right; default is 1: center. barcode.setbarAlignment(0(left));

Java Code 128 Image Resolution, Color and Rotation

      //Code 128 resolution is set in DPI which stands for Dot Per Inch.default is 72;
//Java Code 128 image background color, default is white; barcode.setbackColor(red);
//Java Code 128 fore ground color, which actually is the bar color, default is black; barcode.setforeColor(black);
//the color of the text below the image barcode.settextColor(black);
//rotate the Code 128 image with 0, 90, 180, 270 degrees in Java projects barcode.setRotate(IBarcode.ROTATE_0);

Hide Code 128 Text

Code 128 generator in Java show text can be enable or disable with your need. If the show text property is set to be false, the text of the Code 128 in Java can be hided without showing
