(Java实现)HTML转JPG，TIFF等图片格式和TIFF图片合并功能解决方案。

前一小段时间，发现Apache的一个开源工具，可以把PDF转成图片，没有直接从HTML转图片的jar包，就只能曲线救国了。
忘了介绍了。PDF转图片的包叫做apache pdfBox 右边是：pdfbox的官网 pdfBox官网
下面直接贴代码了：
[java]
public void convertToTiff(String pdfFilePath, String tiffFileName)
            throws Exception {

         PDDocument doc = PDDocument.load(pdfFilePath);
            int pageCount = doc.getPageCount();
            List pages = doc.getDocumentCatalog().getAllPages();
            List<File> files = new ArrayList<File>();
            List<File> deleteFiles = new ArrayList<File>();


            for(int i=0;i<pages.size();i++){
                PDPage page = (PDPage)pages.get(i);
                BufferedImage image = page.convertToImage(BufferedImage.TYPE_BYTE_BINARY, 300);


            Iterator iter = ImageIO.getImageWritersBySuffix("jpg");
            ImageWriter writer = (ImageWriter)iter.next();
            File outFile = new File("C:/1"+i+".jpg");
            FileOutputStream out = new FileOutputStream(outFile);

            ImageOutputStream outImage = ImageIO.createImageOutputStream(out);
            writer.setOutput(outImage);
            writer.write(new IIOImage(image,null,null));


            this.jpg2tif("C:/1"+i+".jpg", "C:/1"+i+".tif");
            files.add(new File("C:/1"+i+".tif"));
            deleteFiles.add(outFile);
            deleteFiles.add(new File("C:/1"+i+".tif"));


            outImage.close();
            out.close();
            writer.dispose();
        }

        if(files != null){
            this.tif2Marge(files, "C:/1.tif");
        }
    }
