How to setup in Maven

JPedal is a Java PDF library that allows developers to view, print, rasterize and extract content from PDF files in their own Java applications.

This tutorial shows how to set up a Maven project using the JPedal jar for development.

Please note: A trial or full copy of the JPedal jar is needed. You can download the trial jar from here or find out how to purchase a license here.

Step 1 - Setup Maven repo and add JPedal code examples

Create the following directory structure:

<project_directory>
|_lib
|_src
|__main
|___java

Get the example file that we have up on GitHub.

Either:

• Run git clone https://github.com/idrsolutions/jpedal-code-example.git from a command line

Or

• Click “Code” -> “Download ZIP” and extract the JPedalExamples.java file

Copy JPedalExamples.java into the src/main/java folder

<project_directory>
|_lib
|_src
|__main
|___java
|____JPedalExamples.java

Create a new file called pom.xml and copy the following contents into it.

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>

    <groupId>org.example</groupId>
    <artifactId>jpedal-example</artifactId>
    <version>1.0-SNAPSHOT</version>

    <dependencies>
        <dependency>
            <groupId>com.idrsolutions</groupId>
            <artifactId>jpedal</artifactId>
            <version>1.0</version>
        </dependency>
    </dependencies>
</project>

Step 2 - Install JPedal jar (trial or full version)

Find your copy of the JPedal jar file and move the jar into the lib directory.

<project_directory>
|_lib
|__**jpedal.jar**
|_src
|__main
|___java
|____JPedalExamples.java

Open the command line in the lib directory and run the following command

mvn install:install-file -Dfile=jpedal.jar -DgroupId=com.idrsolutions -Dpackaging=jar -DartifactId=jpedal -Dversion=1.0

Once done, the dependency can be added to your project. This is already done for the example pom but can be achieved with the <dependency> tag.

Step 3 - Run in Preferred IDE

Open your preferred Java IDE

Select Open project:

• IntelliJ IDEA (Open)
• Eclipse (Import -> Maven -> Existing Maven Projects)
• NetBeans (Open Project)

Select the project folder

Step 4 - Start coding

Uncomment the action that you want to try out from the examples

public static void main(String[] args) {
    try {
        pdfToImage();
//        pdfViewer();
//        extractWords();
//        extractImages();
    } catch (final Exception e) {
        e.printStackTrace();
    }
}

Change the parameters of the action to point to the correct input/output

public static void pdfToImage() throws PdfException {
    ConvertPagesToImages.writeAllPagesAsImagesToDir("/path/to/input/file.pdf",
            "/path/to/output/", "png", 1.33f);
}

Click the run button.
