PDF转图片以及转html

嘿，笔者就是本着有意思的心态。其实实现的原理与ppt转html的一致。先转成图片，然后把图片呈现在html上。直接贴代码喽。

        package com.css.java.learning.massbag;

        import java.awt.image.BufferedImage;
        import java.io.File;
        import java.io.FileOutputStream;
        import java.util.ArrayList;
        import java.util.Iterator;
        import java.util.List;
        import javax.imageio.IIOImage;
        import javax.imageio.ImageIO;
        import javax.imageio.ImageWriter;
        import javax.imageio.stream.ImageOutputStream;
        import org.apache.pdfbox.pdmodel.PDDocument;
        import org.apache.pdfbox.pdmodel.PDPage;

            private static void pdfToHtml(String sourcePath, String outPath){
                List<String> imgList = new ArrayList<String>();
                try {
                    PDDocument doc = PDDocument.load(sourcePath);
                    int pageCount = doc.getPageCount();
                    System.out.println("总共多少页？" + pageCount);
                    List pages = doc.getDocumentCatalog().getAllPages();
                    for(int i=0;i<pages.size();i++){

                            BufferedImage image = page.convertToImage();

                            writer.write(new IIOImage(image,null,null));
                    }
                    doc.close();
                } catch (Exception e) {
                    e.printStackTrace();
                }
                PptToHtml.createPPTHtml(outPath, imgList, sourcePath);

            public static void main(String[] args) {
                pdfToHtml("D:\\red_ant_file\\20180925\\20180925_pdf\\西点烘焙百科全书电子书.pdf",

        }

实现效果
