?pdfPro

@Data
public class PdfPro {private String text;private float x;private float y;private Integer pageNum;public PdfPro(float x, float y, String text) {this.text = text;this.x = x;this.y = y;}public PdfPro(float x, float y, String text,Integer pageNum) {this.text = text;this.x = x;this.y = y;this.pageNum = pageNum;}}

?ImagePro

@Data
public class ImagePro { private float x; //x 坐標private float y; //y 坐標private float scalePercent;  //縮放百分比private String imgPath; //路徑private Integer pageNum;public ImagePro() { }public ImagePro(float x, float y, float scalePercent, String imgPath,Integer pageNum) {this.x = x;this.y = y;this.scalePercent = scalePercent;this.imgPath = imgPath;this.pageNum = pageNum;}

使用示例

public static String getSignPdf(String file, String signUrl, float x, float y,float scalePercent,String agreementNo0,String agreementNo1) {String outPutFile = SsmConstant.WRITE_TO_PDF_URL + UUID.fastUUID() + ".PDF";List<ImagePro> imageList = new ArrayList<>();//蓋章ImagePro imagePro = new ImagePro(x, y, scalePercent, signUrl, 6);imageList.add(imagePro);List<PdfPro> pdfList = new ArrayList<>();// 合同編號if(agreementNo0 != null && agreementNo1 != null){pdfList.add(new PdfPro(471.99628f, 769.37f, agreementNo0));pdfList.add(new PdfPro(500.99628f, 769.37f, agreementNo1));}try {EditorPDF.writeToPdf(file, outPutFile, imageList, pdfList);} catch (Exception e) {throw new BizException("PDF生成異常");}return outPutFile;
