Usage

To get page count
获取PDF页数

import com.testautomationguru.utility.PDFUtil;
 
PDFUtil pdfUtil = new PDFUtil();
pdfUtil.getPageCount("c:/sample.pdf"); //returns the page count

To get page content as plain text
以纯文本的方式获取页面内容

//returns the pdf content - all pages
//以Text返回PDF的内容 - 所有页
pdfUtil.getText("c:/sample.pdf");
 
// returns the pdf content from page number 2
// 以Text返回PDF第2页的内容
pdfUtil.getText("c:/sample.pdf",2);
 
// returns the pdf content from page number 5 to 8
// 以Text返回PDF第5~8页的内容
pdfUtil.getText("c:/sample.pdf", 5, 8);

To extract attached images from PDF
从PDF中提取附加图像

//set the path where we need to store the images
//设置我们需要存储图像的路径
 pdfUtil.setImageDestinationPath("c:/imgpath");
 pdfUtil.extractImages("c:/sample.pdf");
 
// extracts &amp; saves the pdf content from page number 3
// 从PDF的第3页中提取并保存内容
pdfUtil.extractImages("c:/sample.pdf", 3);
 
// extracts &amp; saves the pdf content from page 2
// 从PDF的第2页中提取并保存内容
pdfUtil.extractImages("c:/sample.pdf", 2, 2);

To store PDF pages as images
将PDF页面存储为图像

//set the path where we need to store the images
//设置我们需要存储图像的路径
 pdfUtil.setImageDestinationPath("c:/imgpath");
 pdfUtil.savePdfAsImage("c:/sample.pdf");

To compare PDF files in text mode (faster – But it does not compare the format, images etc in the PDF)
以文本模式比较PDF文件(速度更快-但不比较PDF中的格式、图像等)

String file1="c:/files/doc1.pdf";
String file1="c:/files/doc2.pdf";
 
// compares the pdf documents &amp; returns a boolean
// true if both files have same content. false otherwise.
// 比较PDF文档并返回 True or False
pdfUtil.compare(file1, file2);
 
// compare the 3rd page alone
// 仅比较第3页
pdfUtil.compare(file1, file2, 3, 3);
 
// compare the pages from 1 to 5
// 比较第1~5页
pdfUtil.compare(file1, file2, 1, 5);

To exclude certain text while comparing PDF files in text mode
在文本模式下排除某些文本再对PDF文件进行比较

String file1="c:/files/doc1.pdf";
String file1="c:/files/doc2.pdf";
 
//pass all the possible texts to be removed before comparing
//对比之前删除有可能的文本内容
pdfutil.excludeText("1998", "testautomation");
 
//pass regex patterns to be removed before comparing
//使用正则表达式，在比较之前删除指定内容
// \\d+ removes all the numbers in the pdf before comparing
// \\d+ 在比较之前删除PDF中的所有数字 \\d+是数字的正则表达式
pdfutil.excludeText("\\d+");
 
// compares the pdf documents &amp; returns a boolean
// true if both files have same content. false otherwise.
// 比较PDF文档并返回一个布尔值
// True表示相同；false 表示不一样.
pdfUtil.compare(file1, file2);
 
// compare the 3rd page alone
// 仅比较第3页
pdfUtil.compare(file1, file2, 3, 3);
 
// compare the pages from 1 to 5
// 比较第1~5页
pdfUtil.compare(file1, file2, 1, 5);

To compare PDF files in Visual mode (slower – compares PDF documents pixel by pixel – highlights pdf difference & store the result as image)
以视图模式比较PDF文件(较慢--对PDF文档进行像素逐一比较 -- 高亮PDF差异并将结果存储为图像)

String file1="c:/files/doc1.pdf";
String file1="c:/files/doc2.pdf";
 
// compares the pdf documents &amp; returns a boolean
// true if both files have same content. false otherwise.
// Default is CompareMode.TEXT_MODE
// 比较PDF文档并返回一个布尔值
// 两个PDF完全一样返回True， 不一样返回False
// 默认是 CompareMode.TEXT_MODE
pdfUtil.setCompareMode(CompareMode.VISUAL_MODE);
pdfUtil.compare(file1, file2);
 
// compare the 3rd page alone
pdfUtil.compare(file1, file2, 3, 3);
 
// compare the pages from 1 to 5
pdfUtil.compare(file1, file2, 1, 5);
 
//if you need to store the result
//需要的话，可以将不同的地方高亮并以图像存储到你的本地
pdfUtil.highlightPdfDifference(true);
pdfUtil.setImageDestinationPath("c:/imgpath");
pdfUtil.compare(file1, file2);

For example, I have 2 PDF documents which have exact same content except the below differences in the charts.

The difference is shown as
