package com.example.core.mydemo.aspose; import org.apache.pdfbox.pdmodel.PDDocument; import org.apache.pdfbox.rendering.ImageType; import org.apache.pdfbox.rendering.PDFRenderer; import javax.imageio.ImageIO; import java.awt.image.BufferedImage; import java.io.File; public class PdfToImage { public static void main(String[] args) { String path = "D:\\pdf\\40255371604299_1_sign.pdf"; String path2 = "D:\\pdf"; pdfFileToImages(path,path2); } public static void pdfFileToImages(String filePath, String cachePath) { try { PDDocument pd = PDDocument.load(new File(filePath)); PDFRenderer pdfRenderer = new PDFRenderer(pd); /* dpi越大转换后越清晰,相对转换速度越慢 */ int pages = pd.getNumberOfPages(); System.out.println("pdf总共多少页-----" + pages); for (int page = 0; page < pages; ++page) { BufferedImage image = pdfRenderer.renderImageWithDPI(page, 96, ImageType.RGB); //将图片数据保存为PNG格式文档 File file= new File(cachePath + File.separator + ("new"+page) + ".png"); ImageIO.write(image, "png", file); System.out.println(file.getAbsolutePath()); System.out.println("PDF文档转PNG图片成功!"); } } catch (Exception e) { e.printStackTrace(); } } }
另外一种方法不适用,将word中的图片转换为图片,而不是将word文档转换为图片
package com.example.core.mydemo.aspose; import org.apache.poi.xwpf.usermodel.XWPFDocument; import org.apache.poi.xwpf.usermodel.XWPFPictureData; import java.awt.image.BufferedImage; import java.io.*; import java.util.List; import javax.imageio.ImageIO; /** * 将word中的图片转换为图片,而不是将word文档转换为图片 * https://blog.51cto.com/u_16213439/8905749 */ public class WordToImageConverter { public static void main(String[] args) { try { String wordFilePath = "D:\\pdf\\testword.docx"; String outputImagePath = "D:\\pdf\\image33.png"; XWPFDocument document = new XWPFDocument(new FileInputStream(wordFilePath)); List<XWPFPictureData> pictures = document.getAllPictures(); System.out.println("pictures size=" + pictures.size()); for (int i = 0; i < pictures.size(); i++) { XWPFPictureData picture = pictures.get(i); byte[] pictureData = picture.getData(); BufferedImage image = ImageIO.read(new ByteArrayInputStream(pictureData)); String imageFileName = outputImagePath + "_" + (i + 1) + ".png"; if(image != null) { ImageIO.write(image, "png", new FileOutputStream(new File(imageFileName))); } } document.close(); System.out.println("image ok 2"); } catch (IOException e) { e.printStackTrace(); } } }
