1、Barcode4j使用措施1-using the JavaBean APIpublic static void generateCode128Barcode(File file, String code) Code128Bean bean = new Code128Bean(); final int dpi = 150; /barcode bean.setModuleWidth(0.21); bean.setHeight(15); bean.doQuietZone(true); bean.setQuietZone(2);/两边空白区 /human-readable bean.setFontNa

2、me(Helvetica); bean.setFontSize(3); bean.setMsgPosition(HumanReadablePlacement.HRP_BOTTOM); OutputStream out = null; try out = new FileOutputStream(file); BitmapCanvasProvider canvas = new BitmapCanvasProvider(out, image/jpeg, dpi, BufferedImage.TYPE_BYTE_BINARY, true, 0); bean.generateBarcode(canva

3、s, code); canvas.finish(); catch (Exception e) e.printStackTrace(); finally try if (out != null) out.close(); catch (IOException e) e.printStackTrace(); public static void generateCode39Barcode(int mode, File file, String code) Code39Bean bean = new Code39Bean(); / Dot Per Inch每英寸所打印的点数或线数，用来表达打印机打印

4、辨别率。 final int dpi = 150; / bean.setModuleWidth(UnitConv.in2mm(1.0f / dpi); bean.setModuleWidth(0.2); bean.setHeight(15); bean.setWideFactor(3); bean.doQuietZone(true); OutputStream out = null; try out = new FileOutputStream(file); if (mode = 0) BitmapCanvasProvider canvas = new BitmapCanvasProvider

5、(out, image/jpeg, dpi, BufferedImage.TYPE_BYTE_GRAY, false, 0); bean.generateBarcode(canvas, code); canvas.finish(); else BitmapCanvasProvider canvas = new BitmapCanvasProvider(dpi, BufferedImage.TYPE_BYTE_GRAY, true, 0); bean.generateBarcode(canvas, code); canvas.finish(); BufferedImage barcodeImag

6、e = canvas.getBufferedImage(); ImageIO.write(barcodeImage, jpg, out); catch (Exception e) e.printStackTrace(); finally try if (out != null) out.close(); catch (IOException e) e.printStackTrace(); 2-use XML APIcode39.xml 15mm 0.19mm 2.5 1mw 10mw ignore bottom Helvetica 8pt false false java* * 不同的类型，其

7、属性定义有所有同，最佳是加载xml文献的方式来配备 */ public static Configuration buildCfg(String barcode_type) DefaultConfiguration cfg = new DefaultConfiguration(barcode); DefaultConfiguration barcodeType = new DefaultConfiguration(barcode_type); /* *属性设立* */ addChild(barcodeType,bar-height,15); addChild(barcodeType,modul

8、e-width,0.19); addChild(barcodeType,quiet-zone,10); addChild(barcodeType,wide-factor,2.5); addChild(barcodeType,interchar-gap-width,1); DefaultConfiguration humanReadable = new DefaultConfiguration(human-readable); addChild(humanReadable,placement,bottom); addChild(humanReadable,font-name,Helvetica)

9、; addChild(humanReadable,font-size,3mm); barcodeType.addChild(humanReadable); cfg.addChild(barcodeType); return cfg; /* * 添加子节点 * param parent * param attrName * param attrValue */ public static void addChild(DefaultConfiguration parent,String attrName,Object attrValue) DefaultConfiguration attr; at

10、tr = new DefaultConfiguration(attrName); if(attrValue instanceof String) attr.setValue(String)attrValue); else attr.setValue(Integer)attrValue); parent.addChild(attr); /* * 加载xml配备的条形码属性文献 * param file * return */ public static Configuration buildCfgFromFile(File file) DefaultConfigurationBuilder bu

11、ilder = new DefaultConfigurationBuilder(); Configuration cfg = null; try cfg = builder.buildFromFile(file); catch (Exception e) e.printStackTrace(); return cfg; /* * 生成条形码 * param barcodeType * param code * param file */ public static void generateBarcode(String barcodeType, String code, File file)

12、byte data; ByteArrayOutputStream baos = null; BitmapCanvasProvider bitmap = null; String FORMAT = MimeTypes.MIME_JPEG; int RESOLUTION = 150; int ORIENTATION = 0; try /加载文献方式 /Configuration cfg = buildCfgFromFile(getResourceFile(barcodeType.concat(.xml); Configuration cfg = buildCfg(barcodeType);/程序中

13、的配备属性 BarcodeUtil util = BarcodeUtil.getInstance(); BarcodeGenerator gen = util.createBarcodeGenerator(cfg); baos = new ByteArrayOutputStream(); bitmap = new BitmapCanvasProvider(baos, FORMAT, RESOLUTION, BufferedImage.TYPE_BYTE_GRAY, true, ORIENTATION); gen.generateBarcode(bitmap, code); bitmap.fin

14、ish(); data = baos.toByteArray(); FileOutputStream out = new FileOutputStream(file); out.write(data); catch (Exception e) e.printStackTrace(); finally try if (baos != null) baos.close(); bitmap = null; catch (Exception e) /* * 取资源文献 * param fileName * return */ public static File getResourceFile(Str

15、ing fileName) String path = ClassLoader.getSystemResource().getPath().substring(1) + fileName; return new File(path); 3.测试 public static void main(String args) String code = ISN8859-52036; generateCode39Barcode(0, new File(d:/barcode/code39_0.jpg), code); generateCode39Barcode(1, new File(d:/barcode/code39_1.jpg), code); generateCode128Barcode(new File(d:/barcode/code128.jpg), code); generateBarcode(code39, code, new File(d:/barcode/code39.jpg);
