Some test text!
This guide will help you run PDFTron samples and integrate a free trial of the PDFTron SDK into Java applications on Windows. Your free trial includes unlimited trial usage and support from solution engineers.
JDK >= 5.
Make sure that the JDK has been added to your path
environment variable.
The Troubleshooting section has more information about some of the common Java installation issues.
Extract the folder from the .zip file.
Navigate to the location of extracted contents. Find and enter the Samples
folder. Here you can find sample code for a large number of features supported by the PDFTron SDK.
Run a specific sample
JAVA
folder inside. RunTest.bat
and run it. This can be done using either CLI or with a double-click. The results should appear on a cmd
window. Run all samples
runall_java.bat
in the samples folder and double click it to run it. The results should appear on a cmd
window. This is called the "PDFTron Hello World" application. It is easy to integrate the rest of PDFTron SDK if you are able to open, save and close a PDFDoc.
Samples
by the name HelloWorld
. HelloWorld
folder, create a new file called HelloWorld.java
, open and edit it using your favorite text editor.Insert the following to your file:
import java.io.File;
import java.io.IOException;
// These are the most important packages to import
// for basic document manipulation.
import com.pdftron.common.PDFNetException;
import com.pdftron.pdf.*;
import com.pdftron.sdf.SDFDoc;
import java.io.*;
public class HelloWorld
{
// Just a simple setup for the application
public static void main(String[] args)
{
// PDFNet must always be initialized before any PDFTron
// classes and methods can be used
PDFNet.initialize();
System.out.println("Hello World!");
// Most PDFTron operations are required to be wrapped in
// a try-catch block for PDFNetException, or in a method/class that
// throws PDFNetException
try {
// Creates a new PDFDoc object
PDFDoc doc = new PDFDoc();
// Creating a new page and adding it
// to document's sequence of pages
Page page1 = doc.pageCreate();
doc.pagePushBack(page1);
// Files can be saved with various options
// Linearized files are the most effective
// for opening and viewing quickly on various platforms
doc.save(("linearized_ouput.pdf"), SDFDoc.SaveMode.LINEARIZED, null);
doc.close();
} catch (PDFNetException e) {
System.out.println(e);
e.getStackTrace();
}
PDFNet.terminate();
}
}
To test that your code works, compile and run the code using a shell in the HelloWorld
folder using:
javac -cp .;../../Lib/PDFNet.jar HelloWorld.java
java.exe -Djava.library.path=../../Lib -classpath .;../../Lib/PDFNet.jar HelloWorld
Once you have successfully run this, you should see an output file in the working directory of this program.
