word转图片方法：
1.word转pdf用的是poi,pdf转图片用的是icepdf
/** * 将word文档， 转换成pdf, 中间替换掉变量 * @param source 源为word文档， 必须为docx文档 * @param target 目标输出 * @param params 需要替换的变量 * @throws Exception */ public static void wordConverterToPdf(InputStream source, OutputStream target, Map<String, String> params) throws Exception { wordConverterToPdf(source, target, null, params); } /** * 将word文档， 转换成pdf, 中间替换掉变量 * @param source 源为word文档， 必须为docx文档 * @param target 目标输出 * @param params 需要替换的变量 * @param options PdfOptions.create().fontEncoding( "windows-1250" ) 或者其他 * @throws Exception */ public static void wordConverterToPdf(InputStream source, OutputStream target, PdfOptions options, Map<String, String> params) throws Exception { //HWPFDocument doc=new HWPFDocument(source); XWPFDocument doc = new XWPFDocument(source); paragraphReplace(doc.getParagraphs(), params); for (XWPFTable table : doc.getTables()) { for (XWPFTableRow row : table.getRows()) { for (XWPFTableCell cell : row.getTableCells()) { paragraphReplace(cell.getParagraphs(), params); } } } PdfConverter.getInstance().convert(doc, target, options); } /** 替换段落中内容 */ private static void paragraphReplace(List<XWPFParagraph> paragraphs, Map<String, String> params) { if (MapUtils.isNotEmpty(params)) { for (XWPFParagraph p : paragraphs){ for (XWPFRun r : p.getRuns()){ String content = r.getText(r.getTextPosition()); if(StringUtils.isNotEmpty(content) && params.containsKey(content)) { r.setText(params.get(content), 0); } } } } }
/** * 将指定pdf文件的首页转换为指定路径的缩略图 *@param filepath 原文件路径，例如d:/test.pdf *@param imagepath 图片生成路径，例如 d:/test-1.jpg *@param zoom 缩略图显示倍数，1表示不缩放，0.3则缩小到30% */ public static void tranfer(String filepath, String imagepath, float zoom) throws Exception { // ICEpdf document class Document document = null; float rotation = 0f; document = new Document(); try { document.setFile(filepath); } catch (Exception e1) { e1.printStackTrace(); } Integer maxPages = document.getPageTree().getNumberOfPages(); for (int i = 0; i < maxPages; i ) { // maxPages = document.getPageTree().getNumberOfPages(); Iterator iter = null; ImageWriter writer = null; // 文件输出位置: FileOutputStream out = null; ImageOutputStream outImage = null; BufferedImage img = (BufferedImage) document.getPageImage(i, GraphicsRenderingHints.SCREEN, Page.BOUNDARY_CROPBOX, rotation, zoom); try { File outFile = new File("/users/limeng/ccc4/ccc" i SUFF_IMAGE); iter = ImageIO.getImageWritersBySuffix(FILETYPE_JPG); writer = (ImageWriter) iter.next(); out = new FileOutputStream(outFile); outImage = ImageIO.createImageOutputStream(out); writer.setOutput(outImage); writer.write(new IIOImage(img, null, null)); System.gc(); } catch (IOException e) { e.printStackTrace(); } finally { outImage.flush(); outImage.close(); out.close(); document.dispose(); System.gc(); } } }
public static void main(String[] args) { try {
//word转pdf在走的是office服务，在其他系统上有问题，通用性不好
//pdf转图片方法在各个系统通用 SimpleDateFormat dfs = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"); long c1=Calendar.getInstance().getTimeInMillis(); //路径写成这样，因为我的运行环境是mac系统
String filepath = "/users/limeng/aaa.docx"; String outpath = "/users/limeng/ccc.pdf"; InputStream source = new FileInputStream(filepath); OutputStream target = new FileOutputStream(outpath); Map<String, String> params = new HashMap<String, String>(); PdfOptions options = PdfOptions.create(); wordConverterToPdf(source, target, options, params); tranfer(outpath,"/users/limeng/ccc.jpg",4f); long c2=Calendar.getInstance().getTimeInMillis(); System.out.println((c2-c1)/1000); } catch (Exception e) { e.printStackTrace(); } }
