Let’s dive right in and unlock the potential of this versatile Java library.

Prerequisites

Before we embark on this exciting journey with Aspose.Imaging for Java, you need to make sure you have the following prerequisites in place:

1. Java Development Kit (JDK)

Ensure that you have the Java Development Kit (JDK) installed on your system. Aspose.Imaging for Java requires a compatible Java environment to function smoothly.

2. Aspose.Imaging for Java Library

You’ll need to acquire Aspose.Imaging for Java library, which you can download from the website. Use the following link to access the download page: Download Aspose.Imaging for Java.

3. Document Directory

Create a dedicated document directory where you will store your image files. Make sure to remember the path, as you’ll need it in the code examples.

Now that you have the prerequisites sorted, let’s proceed to import the necessary packages and explore the example step by step.

Import Packages

In your Java project, you need to import the required packages to use Aspose.Imaging for Java effectively. Here’s how you can do it:

import com.aspose.imaging.Image;
import com.aspose.imaging.Size;
import com.aspose.imaging.imageoptions.ImageOptionsBase;
import com.aspose.imaging.imageoptions.otg.OtgRasterizationOptions;
import com.aspose.imaging.imageoptions.pdf.PdfOptions;
import com.aspose.imaging.imageoptions.png.PngOptions;

Ensure that you’ve added these import statements at the beginning of your Java source file.

OTG File Format Support

Let’s explore an example that demonstrates OTG (OpenDocument Drawing Template) file format support using Aspose.Imaging for Java. This example converts an OTG file into both PNG and PDF formats. We’ll break it down into individual steps for a clearer understanding.

Step 1: Define the Data Directory

Set the path to your document directory where the OTG file is located.

String dataDir = "Your Document Directory" + "OTG/";

Replace "Your Document Directory" with the actual path to your document directory.

Step 2: Specify the OTG File Name

Define the OTG file name you want to process.

String fileName = "VariousObjectsMultiPage.otg";

Make sure to replace "VariousObjectsMultiPage.otg" with the name of your OTG file.

Step 3: Prepare Output Options

Create an array of image options that includes both PNG and PDF options.

ImageOptionsBase[] options = { new PngOptions(), new PdfOptions() };

This array will allow you to save the OTG file as both PNG and PDF.

Step 4: Load the OTG Image

Load the OTG image using Aspose.Imaging for Java.

try (Image image = Image.load(inputFileName))

The inputFileName variable should point to the OTG file you want to process.

Step 5: Configure Rasterization Options

Set rasterization options specifically for OTG files.

OtgRasterizationOptions otgRasterizationOptions = new OtgRasterizationOptions();
otgRasterizationOptions.setPageSize(Size.to_SizeF(image.getSize()));

This step ensures that the output matches the original OTG file’s dimensions.

Step 6: Save the Converted Image

Save the converted image in both PNG and PDF formats.

image.save("Your Document Directory" + "output" + fileExt, item);

The "output" portion of the path can be adjusted to your liking, and fileExt will automatically resolve to the correct file extension (either .png or .pdf) based on the image options.

Congratulations! You’ve successfully used Aspose.Imaging for Java to convert an OTG file into PNG and PDF formats.
