Migration from legacy Aspose.Pdf.Kit for Java

Support for Legacy code

During the whole migration activity, we have definitely considered the impact of this activity over existing customers and we have tried our level best to minimize this impact as much as possible. Furthermore, we have also focused on making the new autoported release as backward compatible so that the code base of existing customers requires minimal changes. Even though the new autoported release provides Document Object Model (DOM) under com.aspose.pdf package to create as well as manipulate existing PDF files, but still if you would like to continue using your legacy code developed with Aspose.PDF.Kit for Java, you only need to import com.aspose.pdf.facades package and your code should work (except for updating explicit class references).

The following code snippet shows you how to run your existing Aspose.PDF.Kit for Java code with new autoported Aspose.PDF for Java.

 import com.aspose.pdf.facades.*;

public class template {

    public static void main(String[] args) {


            // load existing PDf file

            com.aspose.pdf.facades.PdfFileInfo fileInfo = new com.aspose.pdf.facades.PdfFileInfo("input.pdf");

            System.out.println("TITLE: " + fileInfo.getTitle());

            System.out.println("AUTHOR:" + fileInfo.getAuthor());

            System.out.println("CREATIONDATE:" + fileInfo.getCreationDate());

            System.out.println("CREATOR:" + fileInfo.getCreator());

            System.out.println("KeyWORDS:" + fileInfo.getKeywords());

            System.out.println("MODDATE:" + fileInfo.getModDate());

Using ReplaceTextStrategy class

In order to migrate code for ReplaceTextStrategy class, the setScope(..) method has been updated to setReplaceScope(..). Please take a look over following code snippet.

 // instantiate PdfContentEditor object

com.aspose.pdf.facades.PdfContentEditor editor = new com.aspose.pdf.facades.PdfContentEditor();

// bind source PDF file


// create replace text strategy

com.aspose.pdf.facades.ReplaceTextStrategy strategy = new com.aspose.pdf.facades.ReplaceTextStrategy();

// set the alignment for text replace


// scope for text replace


// set the replace strategy



// save updated file
