JBarcodeBean 生成条形码 并拼接图片
http://my.oschina.net/ruibo/blog/546364
查了好多博客 好多都用的 EAN8/EAN13/Code39 后来发现生成的条形码都不能把 数字显示完成 就改为了code128
|
1 2 3 4 5 6 7 8 |
Java代码 JBarcodeBean jBarcodeBean = new JBarcodeBean(); jBarcodeBean.setCodeType(new Code128()); jBarcodeBean.setCode("301010025000001877"); BufferedImage img1 = new BufferedImage(300, 100, BufferedImage.TYPE_INT_RGB); img1 = jBarcodeBean.draw(img1); saveToPNG(img1, "4.png"); |
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 |
Java代码 static void saveToJPEG(BufferedImage paramBufferedImage, String paramString) { saveToFile(paramBufferedImage, paramString, "jpeg"); } static void saveToFile(BufferedImage paramBufferedImage, String paramString1, String paramString2) { try { FileOutputStream localFileOutputStream = new FileOutputStream( "d:/test/" + paramString1); ImageUtil.encodeAndWrite(paramBufferedImage, paramString2, localFileOutputStream, 100, 100); localFileOutputStream.close(); } catch (Exception localException) { localException.printStackTrace(); } } |
因为有需要把生成的条形码 拼接在一个图片里 保存

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 |
Java代码 public byte[] getJabCode(String code) throws IOException{ //String code="301010025000001877,301010025000001878"; String[] args=code.split("\\,"); JBarcodeBean jBarcodeBean = new JBarcodeBean(); jBarcodeBean.setLabelPosition(JBarcodeBean.LABEL_BOTTOM); // 条形码类型 jBarcodeBean.setCodeType(new Code128()); // jBarcodeBean.setCodeType(new Code39()); //jBarcodeBean1.setLabelPosition(JBarcodeBean.LABEL_BOTTOM); int width1=200; int height1 =100; BufferedImage imageNew1 = new BufferedImage(width1, height1*args.length , BufferedImage.TYPE_INT_RGB); for(int i=0;i<args.length;i++){ jBarcodeBean.setCode(args[i]); BufferedImage tempimg = new BufferedImage(width1, height1, BufferedImage.TYPE_INT_RGB); tempimg = jBarcodeBean.draw(tempimg); int[] ImageArrayOne1 = new int[width1 * height1]; ImageArrayOne1 = tempimg.getRGB(0, 0, width1, height1, ImageArrayOne1, 0, width1); imageNew1.setRGB(0, 100*i, width1, height1, ImageArrayOne1, 0, width1); } ByteArrayOutputStream out = new ByteArrayOutputStream(); boolean flag = ImageIO.write(imageNew1, "gif", out); byte[] b = out.toByteArray(); //saveToPNG(imageNew1, "imageNew1.png"); return b; } |
