PDF Compare

With the PDF rotation tool, you can Compare your PDF file as you want. The following examples show how to upload a test PDF file and compare PDF using Java languages. Then, output the compare PDF file.

java

// Create a client
CPDFClient client = new CPDFClient(publicKey,secretKey);

// Create a task
// Create an example of a Compare task
CPDFCreateTaskResult result = client.createTask(CPDFDocumentEditorEnum.PDF_CONTENT_COMPARE);
//CPDFCreateTaskResult result = client.createTask(CPDFDocumentEditorEnum.PDF_COVER_COMPARE);

// Get a task id
String taskId = result.getTaskId();

// File handling parameter settings
CPDFOverlayComparisonParameter fileParameter = new CPDFOverlayComparisonParameter();
fileParameter.setInTransparency("0.5");
fileParameter.setNewTransparency("0.5");
fileParameter.setCoverType("0");
fileParameter.setInColor("#FBBDBF");
fileParameter.setNewColor("#93B9FD");

// Upload files
client.uploadFile(new File("test.pdf"), taskId, fileParameter);
client.uploadFile(new File("test1.pdf"), taskId, fileParameter);

// Execute task
client.executeTask(taskId);

// Query TaskInfo
CPDFTaskInfoResult taskInfo = client.getTaskInfo(taskId);

Compare PDF content (Include text and images):

• For one task, you must upload two PDF files. If isSaveTwo is set to "1", the processing result will be in a .zip file, which contains the comparison result files of the two PDFs.
• For the same task, two PDF files must be uploaded. If isSaveTwo is set to "0", the processing result will be in a .pdf file, where the comparison results of the two files are combined into this file.

Needed Parameters

isSaveTwo: Specify whether to generate two output files during content comparison: 1 for yes, 0 for no (default value is 0).

imgCompare: Specify whether to enable image comparison: 1 for yes, 0 for no (default value is 1).

textCompare: Specify whether to enable text comparison: 1 for yes, 0 for no (default value is 1).

replaceColor: Define the color for the replaced content (default value is #93B9FD).

insertColor: Define the color for the inserted content (default value is #C0FFEC).

deleteColor: Define the color for the deleted content (default value is #FBBDBF).

Result:
