Add, Edit, Read and Delete Bookmarks in a PDF Document in Java

It is very useful to add bookmarks to PDF files, especially technical documents and instruction manuals. After you add bookmarks to a PDF file, you can access to a specific part of a PDF file easily and efficiently. In this article, I’ll show you how to add, edit, read and delete bookmarks in a PDF document by using Free Spire.PDF for Java.

Dependency

First of all, please download the latest version of Free Spire.PDF for Java from the link, and add Spire.Pdf.jar to your project as a dependency.

Of course, if you are using maven, you can directly add the following code to your project’s pom.xml file.

Add Bookmarks

The first step of adding bookmarks is to loop through all pages in a PDF file, and then add bookmarks and childbookmarks for each page. At the same time, you can set text color and style for bookmarks by using setColor and setDisplayStyle methods.

import com.spire.pdf.PdfDocument;
import com.spire.pdf.PdfPageBase;
import com.spire.pdf.actions.PdfGoToAction;
import com.spire.pdf.bookmarks.PdfBookmark;
import com.spire.pdf.bookmarks.PdfTextStyle;
import com.spire.pdf.general.PdfDestination;
import com.spire.pdf.graphics.PdfRGBColor;
import java.awt.*;
import java.awt.geom.Point2D;

public class AddBookmark {
    public static void main(String[] args) {
        //Create a PdfDocument instance
        PdfDocument pdf = new PdfDocument();
        //Load a PDF file
        pdf.loadFromFile("C:\\Users\\Test1\\Desktop\\Sample.pdf");
        //Loop through the pages in the PDF file
        for(int i = 0; i< pdf.getPages().getCount();i++) {
            PdfPageBase page = pdf.getPages().get(i);
            //Add bookmark
            PdfBookmark bookmark = pdf.getBookmarks().add(String.format("Bookmark-%s", i + 1));
            //Set destination page and location
            PdfDestination destination = new PdfDestination(page, new Point2D.Float(0, 50));
            bookmark.setAction(new PdfGoToAction(destination));
            //Set text color
            bookmark.setColor(new PdfRGBColor(new Color(139, 7, 126)));
            //Set text style
            bookmark.setDisplayStyle(PdfTextStyle.Bold);

            //Add child bookmark
            PdfBookmark childBookmark = bookmark.add(String.format("ChildBookmark-%s", i + 1));
            //Set destination page and location
            PdfDestination childDestination = new PdfDestination(page, new Point2D.Float(0, 200));
            childBookmark.setAction(new PdfGoToAction(childDestination));
            //Set text color
            childBookmark.setColor(new PdfRGBColor(new Color(255, 127, 80)));
            //Set text style
            childBookmark.setDisplayStyle(PdfTextStyle.Italic);
        }
        //Save the result file
        pdf.saveToFile("output/AddBookmarks.pdf");
    }
}

Output

Edit Bookmarks

Using setTitle, setColor and setDisplayStyle methods, you can change the title, color and style of bookmarks 

and childbookmarks in a PDF file.

import com.spire.pdf.PdfDocument;

import com.spire.pdf.bookmarks.PdfBookmark;

import com.spire.pdf.bookmarks.PdfTextStyle;

import com.spire.pdf.graphics.PdfRGBColor;

import java.awt.*;

public class EditBookmark {

    public static void main(String[] args) {

        //Create a PdfDocument instance

        PdfDocument doc = new PdfDocument();

        //Load the PDF file

        doc.loadFromFile("C:\\Users\\Test1\\Desktop\\AddBookmarks.pdf");

        //Get the first bookmark

        PdfBookmark bookmark = doc.getBookmarks().get(0);

        //Change the title of the bookmark

        bookmark.setTitle("New Title");

        //Change the font color of the bookmark

        bookmark.setColor(new PdfRGBColor(new Color(2, 139, 2)));

        //Change the outline text style of the bookmark

        bookmark.setDisplayStyle(PdfTextStyle.Italic);

        //Edit child bookmarks of the first bookmark

        for (PdfBookmark childBookmark : (Iterable <PdfBookmark>) bookmark) {

            childBookmark.setColor(new PdfRGBColor(new Color(255, 19, 24)));

            childBookmark.setDisplayStyle(PdfTextStyle.Bold);

        }

        //Save the result file

        doc.saveToFile("output/EditBookmarks.pdf");

        doc.close();

    }

    }
Output
Read Bookmarks
To read bookmarks in a PDF file, you first get the bookmark collection by using pdf.getBookmarks() method, 
and then create a .txt file and insert bookmarks in it.

import com.spire.pdf.*;
import com.spire.pdf.bookmarks.PdfBookmark;
import com.spire.pdf.bookmarks.PdfBookmarkCollection;
import java.io.FileWriter;
import java.io.IOException;

public class ReadBookmark {

    public static void main(String[] args) {

        //Create a PdfDocument instance

        PdfDocument pdf = new PdfDocument();

        //Load the PDF file

         pdf.loadFromFile("C:\\Users\\Test1\\Desktop\\AddBookmarks.pdf");

        //Get bookmarkCollection

        PdfBookmarkCollection bookmarkCollection = pdf.getBookmarks();

        //Crate a StringBuilder instance

        StringBuilder stringbuilder = new StringBuilder();

        //Define a method to get bookmarks

        GetBookmarkTitle(bookmarkCollection, stringbuilder);

        //Create a .txt file,and write down bookmarks

        FileWriter writer;

        try {

            writer = new FileWriter("output/ReadBookmark.txt");

            writer.write(stringbuilder.toString());

            writer.flush();

        } catch (IOException e) {

            e.printStackTrace();

        }

        pdf.dispose();

    }

    // Define a method to get the titles of bookmarks

    static void GetBookmarkTitle(PdfBookmarkCollection bookmarkCollection, StringBuilder stringbuilder)

    {

        if (bookmarkCollection.getCount()> 0)

        {

            for(int i = 0 ; i< bookmarkCollection.getCount(); i++ )

            {

                PdfBookmark parentBookmark = bookmarkCollection.get(i);

                stringbuilder.append(parentBookmark.getTitle());

                GetBookmarkTitle(parentBookmark, stringbuilder);

            }

        }

    }

}
Output
Delete Bookmarks
You can easily delete a specific child bookmark, a parent bookmark along with its child bookmarks or
all the bookmarks from a PDF file. 
import com.spire.pdf.PdfDocument;

public class DeleteBookmark {

public static void main(String[]
args) {

//Create a PdfDocument instance

PdfDocument pdf = new PdfDocument();

//Load the PDF file

pdf.loadFromFile("C:\\Users\\Test1\\Desktop\\AddBookmarks.pdf");


//Delete the first child bookmark
//pdf.getBookmarks().get(0).removeAt(0);

//Delete the first bookmark along with its child bookmark

//pdf.getBookmarks().removeAt(0);

//Delete all the bookmarks

pdf.getBookmarks().clear();

//Save the result file
pdf.saveToFile("output/DeleteBookmarks.pdf");

    }

Insert, Hide and Delete Excel Rows and Columns in Java

If you need to add new data or delete existing data in an Excel worksheet, you can insert or delete rows or columns in the worksheet. Besides, you will have a cleaner spreadsheet without deleting data you might need later by hiding rows and columns. In this article, I’ll show you how to insert, hide and delete Excel rows and columns by using Free Spire.XLS for Java.

ADD JAR TO PROJECT

Download the latest version of Free Spire.XLS forJava, unzip it and add Spire.Xls.jar located in the “lib” folder to your Java project as a dependency.

Of course, if you are using maven, you need to add the following code to your project’s pom.xml file.

<repositories>  

        <repository>  

            <id>com.e-iceblue</id>  

            <name>e-iceblue</name>

Using the code
 1. Insert Rows and Columns in Excel 
By using the InsertRow and InsertColumn methods, we can insert one or several rows and
columns in Excel workbook. Below are the code snippets.

import com.spire.xls.*;

public class AddRowsAndColumns {
    public static void main(String[] args) {
        //Load the sample Excel file
        Workbook workbook = new Workbook();
        workbook.loadFromFile("C:\\Users\\Test1\\Desktop\\Sample.xlsx");

        //Get the first worksheet
        Worksheet worksheet = workbook.getWorksheets().get(0);

        //Insert a row into the worksheet.
        worksheet.insertRow(2);

        //Insert a column into the worksheet.
        worksheet.insertColumn(2);

        //Insert multiple rows into the worksheet.
        worksheet.insertRow(5, 2);

        //Insert multiple columns into the worksheet.
        worksheet.insertColumn(5, 2);

        //Save to file.
        workbook.saveToFile("output/InsertRowsAndColumns.xlsx", ExcelVersion.Version2013);
    }
}
Effective screenshot after inserting the empty rows and columns:


2.Hide Rows and Columns in Java
import com.spire.xls.*;

public class HideRowsAndColumns {
    public static void main(String[] args) {
        //Load the sample Excel file
        Workbook workbook = new Workbook();
        workbook.loadFromFile("C:\\Users\\Test1\\Desktop\\InsertRowsAndColumns.xlsx");

        //Get the first worksheet
        Worksheet worksheet = workbook.getWorksheets().get(0);

        //Hide the column of the worksheet.
        worksheet.hideColumn(2);

        //Hide the row of the worksheet
        worksheet.hideRow(3);

        //Save to file.
        workbook.saveToFile("output/HideRowAndColumn.xlsx", ExcelVersion.Version2013);
    }
}
Effective screenshot after hiding the second column and the third row:

3. Delete Rows and Columns in Excel

import com.spire.xls.*;

public class DeleteRowsAndColumns {
    public static void main(String[] args) {
        //Load the sample Excel file
        Workbook workbook = new Workbook();
        workbook.loadFromFile("C:\\Users\\Test1\\Desktop\\InsertRowsAndColumns.xlsx");

        //Get the first worksheet
        Worksheet worksheet = workbook.getWorksheets().get(0);

        //Delete a row from the worksheet.
        worksheet.deleteRow(2);

        //Delete multiple columns from the worksheet.
        worksheet.deleteColumn(5, 2);

        //Save to file.
        workbook.saveToFile("output/DeleteRowAndColumn.xlsx", ExcelVersion.Version2013);
    }
}
Effective screenshot after deleting the second row and the fifth and sixth columns:

Add Shapes to PowerPoint in Java

Shapes in PowerPoint can be used to add interest to any presentation, emphasize a point or create custom graphics based on your requirement. Generally, shapes used in PowerPoint are circles, rectangles, squares, pentagons and so on. Furthermore, individual shapes can be merged in to other complex shapes. Let’s take a look at how to add individual shapes or group shapes to PowerPoint by using Free Spire.Presentation for Java.

ADD SPIRE.PRESENTATION.JAR AS 

DEPENDENCY

Download the latest version of Free Spire.Presentation for Java from the link, unzip it and add Spire.Presentation.jar located in the “lib” folder to your Java IDEA.

Of course, if you are creating a Maven project, you can easily add the jar dependency by adding the following configurations to the pom.xml.
