PDF properties, as a part of a PDF document, are not shown on a page. Those properties contain information on documents, including title, author, subject, keywords, creation date, and creator. Some of the property values will not be produced automatically, and we have to set them by ourselves. This article will show you how to set or retrieve PDF properties programmatically using Spire.PDF for Java.
Install Spire.PDF for Java
First of all, you're required to add the Spire.Pdf.jar file as a dependency in your Java program. The JAR file can be downloaded from this link. If you use Maven, you can easily import the JAR file in your application by adding the following code to your project's pom.xml file.

Set Properties of a PDF Document in Java
The detailed steps of setting PDF properties are as follows.
- Create an object of PdfDocument class.
- Load a PDF document from disk using PdfDocument.loadFromFile() method.
- Set document properties including title, author, subject, keywords, creation date, modification date, creator, and producer using the methods under DocumentInformation object returned by PdfDocument.getDocumentInformation() method.
- Save the document using PdfDocument.saveToFile() method.
- Java
import com.spire.pdf.*;
import java.util.Date;
public class setPDFProperties {
public static void main(String[] args) {
//Create an object of PdfDocument
PdfDocument pdfDocument = new PdfDocument();
//Load a PDF document from disk
pdfDocument.loadFromFile("D:/Samples/Sample.pdf");
//Set the title
pdfDocument.getDocumentInformation().setTitle("PDF(Portable Document Format)");
//Set the author
pdfDocument.getDocumentInformation().setAuthor("John");
//Set the subject
pdfDocument.getDocumentInformation().setSubject("Introduction of PDF");
//Set the keywords
pdfDocument.getDocumentInformation().setKeywords("PDF, document format");
//Set the creation time
pdfDocument.getDocumentInformation().setCreationDate(new Date());
//Set the creator name
pdfDocument.getDocumentInformation().setCreator("John");
//Set the modification time
pdfDocument.getDocumentInformation().setModificationDate(new Date());
//Set the producer name
pdfDocument.getDocumentInformation().setProducer("Spire.PDF for Java");
//Save the document
pdfDocument.saveToFile("output/setPDFProperties.pdf");
}
}
Get Properties of a PDF Document in Java
The detailed steps of retrieving PDF properties are as follows.
- Create an object of PdfDocument class.
- Load a PDF document from disk using PdfDocument.loadFromFile() method.
- Create a StringBuilder instance to store the values of document properties.
- Get properties using the methods under DocumentInformation object returned by PdfDocument.getDocumentInformation() method and put them in the StringBuilder.
- Create a new TXT file using File.createNewFile() method.
- Write the StringBuilder to the TXT file using BufferedWriter.write() method.
- Java
import com.spire.pdf.*;
import java.io.*;
public class getPDFProperties {
public static void main(String[] args) throws IOException {
//Create an object of PdfDocument class
PdfDocument pdf = new PdfDocument();
//Load a PDF document from disk
pdf.loadFromFile("D:/Samples/Sample.pdf");
//Create a StringBuilder instance to store the values of document properties
StringBuilder stringBuilder = new StringBuilder();
//Retrieve property values and put them in the StringBuilder
stringBuilder.append("Title: " + pdf.getDocumentInformation().getTitle() + "\r\n");
stringBuilder.append("Author: " + pdf.getDocumentInformation().getAuthor() + "\r\n");
stringBuilder.append("Subject: " + pdf.getDocumentInformation().getSubject() + "\r\n");
stringBuilder.append("Keywords: " + pdf.getDocumentInformation().getKeywords() + "\r\n");
stringBuilder.append("Creator: " + pdf.getDocumentInformation().getCreator() + "\r\n");
stringBuilder.append("Creation Date: " + pdf.getDocumentInformation().getCreationDate() + "\r\n");
stringBuilder.append("Producer: " + pdf.getDocumentInformation().getProducer() + "\r\n");
//Create a new TXT file
File file = new File("D:/output/getPDFProperties.txt");
file.createNewFile();
//Write the StringBuilder to the TXT file
FileWriter fileWriter = new FileWriter(file, true);
BufferedWriter bufferedWriter = new BufferedWriter(fileWriter);
bufferedWriter.write(stringBuilder.toString());
bufferedWriter.flush();
}

When creating PDF, it’s important to use appropriate fonts in different situations. For normal PDF files, you can draw text with common fonts such as Arial, Times New Roman. If you want to create a distinctive PDF with a unique visual identity, you can use private fonts. This article will demonstrate how to use different fonts in a PDF document with Spire.PDF for Java library.

First of all, you're required to add the Spire.Pdf.jar file as a dependency in your Java program. The JAR file can be downloaded from this link. If you use Maven, you can easily import the JAR file in your application by adding the following code to your project's pom.xml file.

Apply Different Fonts in a PDF Document in Java
Spire.PDF for Java supports standard PDF fonts, TrueType fonts, private fonts as well as CJK font. The following are the steps to draw text in PDF using these fonts.
- Create a PdfDocument instance.
- Add a page and then create a brush.
- Create an instance of the PdfFont class with a standard PDF font, and then use the PdfPageBase.getCanvas().drawString() method to draw text on the page with the standard font.
- Create an instance of the PdfTrueTypeFont class with a specified font, and then draw text on the page with the TrueType font.
- Load a private font and create an instance of the PdfTrueTypeFont class with it. Then draw text on the page with the private font.
- Create an instance of PdfCjkStandardFont class with a CJK font, and then draw text on the page with the CJK font.
- Save the result document using PdfDocument.saveToFile() method.
- Java
import com.spire.pdf.PdfDocument;
import com.spire.pdf.PdfPageBase;
import com.spire.pdf.graphics.*;
public class PdfFonts {
public static void main(String[] args) {
//Create a PdfDocument instance
PdfDocument pdf = new PdfDocument();
//Add a page
PdfPageBase page = pdf.getPages().add();
//Create a brush
PdfBrush brush = PdfBrushes.getBlack();
//Initialize y coordinate
float y = 30;
//Draw text using standard fonts
PdfFont standardFont = new PdfFont(PdfFontFamily.Helvetica, 14f);
page.getCanvas().drawString("Standard Font - Helvetica", standardFont, brush, 0, y);
standardFont = new PdfFont(PdfFontFamily.Times_Roman, 14f);
page.getCanvas().drawString("Standard Font - Times_Roman", standardFont, brush, 0, (y = y + 16));
standardFont = new PdfFont(PdfFontFamily.Courier, 14f);

Lists are a great way to organize your information. When compared to chunks of text, it is usually easier to identify important points from a list. There are generally two different types of lists in PDF: order list and unorder list. You can also mix these two types in a nested list. In this article, you will learn how to create various types of lists in a PDF document using Spire.PDF for Java.
- Create an Ordered List in PDF
- Create an Unordered List with Symbol Bullets in PDF
- Create an Unordered List with Image Bullets in PDF
- Create a Nested Numbered List in PDF
Spire.PDF for Java provides the PdfSortedList class and the PdfUnorderedList class to represent the ordered list and the unordered list, respectively. To set the list’s content, indent, font, marker style and other attributes, use the methods under these two classes. The following table lists some of the core items involved in this tutorial.
| Member | Description |
| PdfSortedList class | Represents an ordered list in a PDF document. |
| PdfUnorderedList class | Represents an unordered list in a PDF document. |
| PdfListBase.setBrush() method | Sets a list's brush. |
| PdfListBase.setFont() method | Sets a list's font. |
| PdfListBase.sertIndent() method | Sets a list's indent. |
| PdfListBase.setTextIndent() method | Sets the indent from the marker to the list item text. |
| PdfListBase.getItems() method | Gets items of a list. |
| PdfListBase.setMarker() method | Sets the marker of a list. |
| PdfListBase.draw() method | Draw list on the canvas of a page at the specified location. |
| PdfOrderedMarker class | Represents the marker style of an ordered list, such as numbers, letters, and roman numerals. |
| PdfMarker class | Represents bullet style for an unordered list. |
