Converting a PS file to a JPEG2000 image in Java is a simple two-step process. The first step is to use the Aspose.PDF for Java API to export the PS file to a JPEG image. Aspose.PDF for Java is a powerful PDF manipulation API that is part of the Aspose.Total for Java package. It allows you to easily convert PS files to JPEG images with just a few lines of code. The second step is to use the Aspose.Imaging for Java API to render the JPEG image to a JPEG2000 image. Aspose.Imaging for Java is an advanced image processing API that is also part of the Aspose.Total for Java package. It provides a wide range of image processing capabilities, including the ability to render JPEG images to JPEG2000 images. With just a few lines of code, you can easily convert a JPEG image to a JPEG2000 image. In summary, converting a PS file to a JPEG2000 image in Java is a straightforward process that can be accomplished in two simple steps. By using the Aspose.PDF for Java API to export the PS file to a JPEG image, and then using the Aspose.Imaging for Java API to render the JPEG image to a JPEG2000 image, you can quickly and easily convert a PS file to a JPEG2000 image in Java.
Export PS to JPEG2000 via Java
Get Started with Java File Automation APIs
You can easily use Aspose.Total for Java directly from a Maven based project and include libraries in your pom.xml.
Alternatively, you can get a ZIP file from downloads .
Convert PS to JPEG2000 in a Single File via Java
The API also allows you to export PS file to JPEG2000 to a single file. In order to convert all pages, you can first render your PS document to one TIFF file and after that, you can export the TIFF file to JPEG2000. You can open the input file using Document class and create Resolution, TiffSettings, & TIFF device objects. You can get a single TIFF image using process method of TiffDevice class. Finally, you can load TIFF file using Image class and save it to JPEG2000 format using save method.
Convert PS to JPEG2000 With Watermark via Java
Using the API, you can also export PS file to JPEG2000 with watermark in your JPEG2000 document. In order to add a watermark to you can first convert PS to JPEG and add a watermark in it. In order to add watermark, load an image file using the Image class, create an object of the Graphics class and initialize it with Image object, create a new Matrix object and set translation and transformation to the desired angle and add watermark using Graphics.drawString method. After adding the watermark in your image, you can save the JPEG as JPEG2000 format.
Convert & Rotate PS to JPEG2000 File via Java
Using the API, you can also rotate the output JPEG2000 image as per your needs. The Image.rotateFlip method can be used to rotate the image by 90/180/270-degrees and flip the image horizontally or vertically. The library provides simple methods to perform complex operations while encapsulating all ugly details. You can specify the type of rotation and flip to apply to the image. In order to rotate and flip the image, you can load the converted JPEG image using the Image class and call the Image.rotateFlip method while specifying the appropriate RotateFlipType .

What is PS File Format?
The PS (PostScript) file format is a page description language developed by Adobe Systems. It is commonly used for printing and is supported by a wide range of printers and imaging devices. PS files contain instructions that describe how elements such as text, images, and graphics should be rendered on a printed page.
PS files are created by applications that generate PostScript output, such as Adobe Illustrator, Adobe InDesign, or other graphics software. They are primarily used in professional printing workflows, where high-quality and consistent output is required.
The PS file format is based on a stack-based programming language, where commands and operands are placed on a stack and executed in a sequential manner. This allows for precise control over page layout, typography, color, and other printing parameters.
PS files are typically text-based and can be opened and edited with a text editor. They consist of a series of ASCII characters that represent the PostScript code. The code describes the arrangement and appearance of objects on a page, including text positioning, image placement, and graphical transformations.
While PS files are primarily used for printing, they can also be converted to other formats for digital distribution or further processing. For example, PS files can be converted to PDF (Portable Document Format) files, which are widely supported and can be easily viewed and printed on various devices.
What is JPEG2000 File Format?
JPEG2000 is an advanced file format developed by the Joint Photographic Experts Group (JPEG) as an extension of the popular JPEG image format. It was designed to provide superior image quality and efficient compression compared to other formats available at the time. JPEG2000 incorporates several key features that contribute to its advantages in various applications.
One notable feature of JPEG2000 is its utilization of wavelet-based compression. Unlike the discrete cosine transform (DCT) used in traditional JPEG, wavelet-based compression allows for more efficient compression rates while preserving higher image quality. This makes JPEG2000 particularly well-suited for applications that require both high compression and excellent image fidelity, such as medical imaging, digital cinema, and satellite imagery.
A significant benefit of JPEG2000 is its support for lossless compression. Lossless compression enables the reduction in file size without sacrificing any original image data. This is crucial in applications where data preservation is essential, including archiving and storage of critical images or documents. JPEG2000’s lossless compression capability ensures that no data is lost during the compression process, maintaining the integrity of the original image.
JPEG2000 is also scalable, which means it allows for the creation of multiple versions of the same image with varying levels of detail. This scalability feature enables the generation of images at different resolutions or quality levels from a single compressed file, offering flexibility in various scenarios. For instance, it can be useful in applications where images need to be delivered at different levels of detail based on the available bandwidth or display capabilities.
