使用aspose进行将word转换为图片格式

项目为maven项目，因为使用的是破解版的aspose.jar包，所以使用引用外部jar包方式直接将包打入项目中build即可

将word文件路径与文件名传入saveImage方法 调用即可生成图片

public String saveImage(String filePath, String fileName){ //word2pdf("C:/Users/Administrator/Desktop/1.doc","C:/Users/Administrator/Desktop/xxxx.pdf");//word转pdf //word转图片格式 try { File file = new File(filePath+fileName); System.out.println(filePath+fileName); InputStream inStream = new FileInputStream(file); Document doc = new Document(filePath+fileName); int pageCount = doc.getPageCount(); System.out.println(pageCount); List<BufferedImage> wordToImg = wordToImg(inStream,pageCount+2);// BufferedImage mergeImage = mergeImage(false, wordToImg); String imgPath = "D:/ruoyi/uploadPath/avatar/" +UUID.randomUUID()+".png"; ImageIO.write(mergeImage, "jpg",new File( imgPath)); try { inStream.close(); } catch (IOException e1) { e1.printStackTrace(); } if (file.isFile() && file.exists()) { file.delete(); } return imgPath; } catch (Exception e) { // TODO Auto-generated catch block e.printStackTrace(); } return null; } /** * @Description: word和txt文件转换图片 */ private static List<BufferedImage> wordToImg(InputStream inputStream, int pageNum) throws Exception { if (!isWordLicense()) { return null; } try { long old = System.currentTimeMillis(); Document doc = new Document(inputStream); ImageSaveOptions options = new ImageSaveOptions(SaveFormat.PNG); options.setPrettyFormat(true); options.setUseAntiAliasing(true); options.setUseHighQualityRendering(true); int pageCount = doc.getPageCount(); if (pageCount > pageNum) {//生成前pageCount张 pageCount = pageNum; } List<BufferedImage> imageList = new ArrayList<BufferedImage>(); for (int i = 0; i < pageCount; i++) { OutputStream output = new ByteArrayOutputStream(); options.setPageIndex(i); doc.save(output, options); ImageInputStream imageInputStream = javax.imageio.ImageIO.createImageInputStream(parse(output)); imageList.add(javax.imageio.ImageIO.read(imageInputStream)); } return imageList; } catch (Exception e) { e.printStackTrace(); throw e; } } //outputStream转inputStream public static ByteArrayInputStream parse(OutputStream out) throws Exception { ByteArrayOutputStream baos = new ByteArrayOutputStream(); baos = (ByteArrayOutputStream) out; ByteArrayInputStream swapStream = new ByteArrayInputStream(baos.toByteArray()); return swapStream; } /** * 合并任数量的图片成一张图片 * * @param isHorizontal true代表水平合并，fasle代表垂直合并 * @param imgs 待合并的图片数组 * @return * @throws IOException */ public static BufferedImage mergeImage(boolean isHorizontal, List<BufferedImage> imgs) throws IOException { // 生成新图片 BufferedImage destImage = null; // 计算新图片的长和高 int allw = 0, allh = 0, allwMax = 0, allhMax = 0; // 获取总长、总宽、最长、最宽 for (int i = 0; i < imgs.size(); i++) { BufferedImage img = imgs.get(i); allw += img.getWidth(); if (imgs.size() != i + 1) { allh += img.getHeight() + 5; } else { allh += img.getHeight(); } if (img.getWidth() > allwMax) { allwMax = img.getWidth(); } if (img.getHeight() > allhMax) { allhMax = img.getHeight(); } } // 创建新图片 if (isHorizontal) { destImage = new BufferedImage(allw, allhMax, BufferedImage.TYPE_INT_RGB); } else { destImage = new BufferedImage(allwMax, allh, BufferedImage.TYPE_INT_RGB); } Graphics2D g2 = (Graphics2D) destImage.getGraphics(); g2.setBackground(Color.LIGHT_GRAY); g2.clearRect(0, 0, allw, allh); g2.setPaint(Color.RED); // 合并所有子图片到新图片 int wx = 0, wy = 0; for (int i = 0; i < imgs.size(); i++) { BufferedImage img = imgs.get(i); int w1 = img.getWidth(); int h1 = img.getHeight(); // 从图片中读取RGB int[] ImageArrayOne = new int[w1 * h1]; ImageArrayOne = img.getRGB(0, 0, w1, h1, ImageArrayOne, 0, w1); // 逐行扫描图像中各个像素的RGB到数组中 if (isHorizontal) { // 水平方向合并 destImage.setRGB(wx, 0, w1, h1, ImageArrayOne, 0, w1); // 设置上半部分或左半部分的RGB } else { // 垂直方向合并 destImage.setRGB(0, wy, w1, h1, ImageArrayOne, 0, w1); // 设置上半部分或左半部分的RGB } wx += w1; wy += h1 + 5; } return destImage; }

也可以将word直接转换为pdf输出，将pdf转换为图片。本项目中暂不采取这种措施，因为来回发生效率问题

public static void word2pdf(String docPath,String savePath){ try { String s = "<License><Data><Products><Product>Aspose.Total for Java</Product><Product>Aspose.Words for Java</Product></Products><EditionType>Enterprise</EditionType><SubscriptionExpiry>20991231</SubscriptionExpiry><LicenseExpiry>20991231</LicenseExpiry><SerialNumber>8bfe198c-7f0c-4ef8-8ff0-acc3237bf0d7</SerialNumber></Data><Signature>sNLLKGMUdF0r8O1kKilWAGdgfs2BvJb/2Xp8p5iuDVfZXmhppo+d0Ran1P9TKdjV4ABwAgKXxJ3jcQTqE/2IRfqwnPf8itN8aFZlV3TJPYeD3yWE7IT55Gz6EijUpC7aKeoohTb4w2fpox58wWoF3SNp6sK6jDfiAUGEHYJ9pjU=</Signature></License>"; ByteArrayInputStream is = new ByteArrayInputStream(s.getBytes()); License license = new License(); license.setLicense(is); com.aspose.words.Document document = new com.aspose.words.Document(docPath); document.save(new FileOutputStream(new File(savePath)),SaveFormat.PDF); } catch (Exception e) { e.printStackTrace(); } }
