A PDF portfolio allows multiple files to be assembled into a single interactive PDF container. The files in a PDF portfolio can be text documents, spreadsheets, presentations, images, videos, audio files, and more. By creating PDF portfolios, you can consolidate all of the relevant materials for a project into one unified package, making it easier to manage and distribute files. This article will demonstrate how to programmatically create a PDF portfolio and add files and folders to it 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.

Create a PDF Portfolio and Add Files to It in Java
As a PDF portfolio is a collection of files, Spire.PDF for Java allows you to create it easily using the PdfDocument.getCollection() method. Then you can add files to the PDF portfolio using the PdfCollection.addFile() method. The detailed steps are as follows:
- Specify the files that need to be added to the PDF portfolio.
- Create a PdfDocument instance.
- Create a PDF portfolio and add files to it using PdfDocument.getCollection().addFile() method.
- Save the result file using PdfDocument.saveToFile() method.
- Java
import com.spire.pdf.FileFormat;
import com.spire.pdf.PdfDocument;
public class CreatePortfolioWithFiles {
public static void main(String []args){
// Specify the files
String[] files = new String[] { "Input.pdf", "Sample.docx", "Report.xlsx","Intro.pptx","Logo.jpg" };
//Create a PdfDocument instance
PdfDocument pdf = new PdfDocument();
//Create a PDF Portfolio and add files to it
for (int i = 0; i < files.length; i++)
{
pdf.getCollection().addFile(files[i]);
}
//Save the result file
pdf.saveToFile("PortfolioWithFiles.pdf", FileFormat.PDF);
pdf.dispose();
}
}
Create a PDF Portfolio and Add Folders to It in Java
After creating a PDF portfolio, Spire.PDF for Java also allows you to create folders within the PDF portfolio to further manage the files. The detailed steps are as follows:
- Specify the files that need to be added to the PDF portfolio.
- Create PdfDocument instance.
- Create a PDF portfolio using PdfDocument.getCollection() method.
- Add folders to the PDF portfolio using PdfCollection.getFolders().createSubfolder() method, and then add files to the folders using PdfFolder.addFile() method.
- Save the result file using PdfDocument.saveToFile() method.
- Java
import com.spire.pdf.FileFormat;
import com.spire.pdf.PdfDocument;
import com.spire.pdf.collections.PdfFolder;
public class CreatePortfolioWithFolders {
public static void main(String []args){
// Specify the files
String[] files = new String[] { "Input.pdf", "Sample.docx", "Report.xlsx","Intro.pptx","Logo.jpg" };
//Create a PdfDocument instance
PdfDocument pdf = new PdfDocument();
//Create a portfolio and add folders to it
for (int i = 0; i < files.length; i++)
{
PdfFolder folder = pdf.getCollection().getFolders().createSubfolder("folder" + i);
//Add files to the folders
folder.addFile(files[i]);
}
//Save the result file
pdf.saveToFile("PortfolioWithFolders.pdf", FileFormat.PDF);
pdf.dispose();
}
}

Invisiblize Textual Data When Creating Barcode&QR code in Java
2021-07-02 02:27:06 Written by KoohjiIn this tutorial, we are going to introduce how to invisiblize the textual data in the middle of creating a Barcode&QR code using Spire.Barcode for Java and its settings.setShowText(false); method.
Invisiblize the Textual Data When Creating a Barcode
import com.spire.barcode.BarCodeGenerator;
import com.spire.barcode.BarCodeType;
import com.spire.barcode.BarcodeSettings;
import javax.imageio.ImageIO;
import java.awt.*;
import java.awt.image.BufferedImage;
import java.io.File;
import java.io.IOException;
public class CreateBarcode {
public static void main(String[] args) throws IOException {
BarcodeSettings settings = new BarcodeSettings();//Instantiate BarcodeSettings object
settings.setType(BarCodeType.Codabar);//Set the Barcode type
settings.setData("123456789");//Set the Barcode data
settings.setShowText(false);//Make the textual data invisible
settings.setShowTextOnBottom(true);//Make the textual data visible at the bottom of the Barcode
settings.setX(0.8f);//Set width for the black and white stripes
settings.setImageHeight(50);//Set height for the created Barcode image
settings.setImageWidth(70);//Set width for the created Barcode image
settings.hasBorder(true);//Make the border visible
settings.setBorderColor(new Color(135,206,250));//Set the border color
settings.setBorderWidth(1);//Set the border width
settings.setBackColor(new Color(240,255,255));//Set background color for the Barcode
BarCodeGenerator barCodeGenerator = new BarCodeGenerator(settings);//Instantiage BarCodeGenerator object
BufferedImage bufferedImage = barCodeGenerator.generateImage();//Generate image data based on settings and save it to BufferedImage instance
ImageIO.write(bufferedImage, "png", new File("Codabar.png"));//Save the Barcode as PNG
}
}

This article demonstrates how to set text horizontal and vertical alignment within a shape using Spire.Presentation for Java.
import com.spire.presentation.*;
import com.spire.presentation.drawing.FillFormatType;
import java.awt.*;
import java.awt.geom.Rectangle2D;
public class SetTextAlignment {
public static void main(String[] args) throws Exception {
//Create a Presentation object
Presentation presentation = new Presentation();
presentation.getSlideSize().setType(SlideSizeType.SCREEN_16_X_9);
//Add a shape
IAutoShape textShape = presentation.getSlides().get(0).getShapes().appendShape(ShapeType.RECTANGLE, new Rectangle2D.Float(50, 50, 400, 200));
textShape.getShapeStyle().getLineColor().setColor(Color.DARK_GRAY);
textShape.getFill().setFillType(FillFormatType.NONE);
//Remove the default paragraphs
textShape.getTextFrame().getParagraphs().clear();
//Add a paragraph and append some text to it
textShape.getTextFrame().getParagraphs().append(new ParagraphEx());
textShape.getTextFrame().getParagraphs().get(0).getTextRanges().append(new PortionEx("Text Alignment"));
textShape.getTextFrame().getParagraphs().get(0).getTextRanges().get(0).setFontHeight(20f);
textShape.getTextFrame().getParagraphs().get(0).getTextRanges().get(0).setLatinFont(new TextFont("Arial"));
textShape.getTextFrame().getParagraphs().get(0).getTextRanges().get(0).getFill().setFillType(FillFormatType.SOLID);
textShape.getTextFrame().getParagraphs().get(0).getTextRanges().get(0).getFill().getSolidColor().setColor(Color.BLACK);
//Set text horizontal alignment to right
textShape.getTextFrame().getParagraphs().get(0).setAlignment(TextAlignmentType.RIGHT);
//Set text vertical alignment to bottom
textShape.getTextFrame().setAnchoringType(TextAnchorType.BOTTOM);
//Save to file
presentation.saveToFile("output/TextAlignment.pptx",FileFormat.PPTX_2013);
}
