此代碼創建BarCode圖像以及圖像下方的文本。 我需要從圖像中刪除文字。 Code39Bean沒有任何屬性來禁用此功能。在Code39Bean中的條碼圖像下方禁用文本
public static ByteArrayOutputStream generateBarcodeImg(String inputId)
throws Exception {
ByteArrayOutputStream baos = new ByteArrayOutputStream();
Code39Bean bean = new Code39Bean();
final int dpi = 150;
/**
* Configure the bar-code generator and makes the narrow bar width
* exactly one pixel.
*/
bean.setModuleWidth(UnitConv.in2mm(1.0f/dpi));
bean.setWideFactor(3);
bean.doQuietZone(false);
try {
/** Set up the canvas provider for monochrome PNG output. */
BitmapCanvasProvider canvas = new BitmapCanvasProvider(baos,
BarCodeConstant.CONTENT_TYPE, dpi,
BufferedImage.TYPE_BYTE_BINARY, false, 0);
/** Generate the bar code. */
bean.generateBarcode(canvas, inputId);
/** Signal end of generation. */
canvas.finish();
