How to create pptx file for Link-Video in Slide using Apache-POI

I want to create pptx file having linked-Video in slides using Apache-poi.
I got one example in Apache-Examples code
poi-4.1.2\src\scratchpad\testcases\org\apache\poi\hslf\model\TestMovieShape.
Using this example I can able to create .ppt file but it's not creating .pptx file.
Also using this example media-controls are not visible.

Only a few lines needed to be changed opposed to the embedded video case.
The video URI is not a real URI, but simply a relative .mp4 filename in the same directory. Although I haven't tested it, absolute file URIs should also work.
I haven't implemented the frame extraction, as it's mentioned in the embedded example - so either look for an archived version of xuggler or find a different library to extract the preview image.
Tested with Powerpoint 2016 / POI 5.0.0-Snapshot.

Convert Extent Report HTML file to PDF

I am trying to convert Extent report HTML file to PDF, however i did not succeed.
Below is the code i tried.
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import com.itextpdf.text.Document;
import com.itextpdf.text.DocumentException;
import com.itextpdf.text.pdf.PdfWriter;
import com.itextpdf.tool.xml.XMLWorkerHelper;
public class Demo
{
public static void main( String[] args ) throws DocumentException, IOException
{
Document document = new Document();
PdfWriter writer = PdfWriter.getInstance(document, new FileOutputStream("pdf.pdf"));
document.open();
XMLWorkerHelper.getInstance().parseXHtml(writer, document,new FileInputStream("html.html"));
document.close();
System.out.println( "PDF Created!" );
}
}

Try this example. You did not create the file and trying to fill it.
package sandbox.xmlworker;
import com.itextpdf.text.Document;
import com.itextpdf.text.DocumentException;
import com.itextpdf.text.pdf.PdfWriter;
import com.itextpdf.tool.xml.XMLWorkerHelper;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import sandbox.WrapToTest;
#WrapToTest
public class D02_ParseHtml {
public static final String HTML = "resources/xml/walden.html";
public static final String DEST = "results/xmlworker/walden1.pdf";
/**
* Html to pdf conversion example.
* #param file
* #throws IOException
* #throws DocumentException
*/
public void createPdf(String file) throws IOException, DocumentException {
// step 1
Document document = new Document();
// step 2
PdfWriter writer = PdfWriter.getInstance(document, new FileOutputStream(file));
// step 3
document.open();
// step 4
XMLWorkerHelper.getInstance().parseXHtml(writer, document,
new FileInputStream(HTML));
// step 5
document.close();
}
/**
* Main method
*/
public static void main(String[] args) throws IOException, DocumentException {
File file = new File(DEST);
file.getParentFile().mkdirs();
new D02_ParseHtml().createPdf(DEST);
}
}

Finally found a work around for it. So what I have done is Added A css file with some adjustments in to the html and was able to covert to PDF and print with attached screenshots.

Importing PDF to String in java

i need to extract text from a pdf file using java. I found iText but it doesn't work the way i wanted it to. Here's my code
package com.itextpdf.mavenproject1;
import com.itextpdf.forms.PdfAcroForm;
import com.itextpdf.forms.fields.PdfButtonFormField;
import com.itextpdf.forms.fields.PdfFormField;
import com.itextpdf.io.font.FontConstants;
import com.itextpdf.kernel.font.PdfFontFactory;
import com.itextpdf.kernel.geom.Rectangle;
import com.itextpdf.kernel.pdf.PdfDocument;
import com.itextpdf.kernel.pdf.PdfReader;
import com.itextpdf.text.pdf.parser.PdfTextExtractor;
import com.itextpdf.kernel.pdf.PdfString;
import com.itextpdf.kernel.pdf.PdfWriter;
import com.itextpdf.kernel.pdf.action.PdfAction;
import com.itextpdf.kernel.pdf.annot.PdfAnnotation;
import com.itextpdf.kernel.pdf.annot.PdfTextAnnotation;
import com.itextpdf.kernel.pdf.canvas.PdfCanvas;
import com.itextpdf.kernel.pdf.canvas.parser.PdfTextExtractor;
import com.itextpdf.test.annotations.WrapToTest;
import java.io.File;
import java.io.IOException;
public class zczytywanie {
public static void main(String args[]) throws IOException {
PdfDocument pdfDoc = new PdfDocument(new PdfReader("D:/pdf/pdf"));
String page= PdfTextExtractor.getTextFromPage(pdfDoc, 1);
System.out.println(page);
}
}
And it tells me that there is an error in the line where i try to use PDdfTextExtractor (PdfDocument can not be converted to pdfPage, although i found that pdfDoc has to be PdfReader)
It doesn't work with
PdfReader pdfDoc = new PdfReader("D:/pdf/pdf");
either.

You can try PDFBox or Tikka. But here I am giving an example for PDFBox
Add the PDFBox jar dependency to your pom.xml.
<dependencies>
<dependency>
<groupId>org.apache.pdfbox</groupId>
<artifactId>pdfbox</artifactId>
<version>2.0.23</version>
</dependency>
</dependencies>
Java class
import org.apache.pdfbox.pdmodel.PDDocument;
import org.apache.pdfbox.text.PDFTextStripper;
import org.apache.pdfbox.text.PDFTextStripperByArea;
import java.io.File;
import java.io.IOException;
public class TestPDF {
public static void main(String[] args) {
try (PDDocument document = PDDocument.load(new File("/path_to_your_pdf_file"))) {
document.getClass();
if(!document.isEncrypted()){
PDFTextStripperByArea stripper = new PDFTextStripperByArea();
stripper.setSortByPosition(true);
PDFTextStripper tStripper = new PDFTextStripper();
String pdfFileInText = tStripper.getText(document);
System.out.println("Text:" + pdfFileInText);
}
} catch (IOException e) {
e.printStackTrace();
}
}
}
