Convert EPUB to JPEG2000 via Java
Export EPUB file to JPEG2000 within any within any Java J2SE, J2EE, J2ME applications without using Adobe® Acrobat Reader
Converting an epub file to a JPEG2000 image in Java is a straightforward process that can be completed in two simple steps. The first step is to use the Aspose.PDF for Java API, which is part of the Aspose.Total for Java package. This API allows you to export an EPUB file to a JPEG image. The second step is to use the Aspose.Imaging for Java API, which is also part of the Aspose.Total for Java package. This API allows you to render the JPEG image to a JPEG2000 image.
The Aspose.PDF for Java API is a powerful library that enables developers to create, edit, and convert PDF documents in Java applications. It provides a wide range of features, such as the ability to export EPUB files to JPEG images. The API also supports a variety of other file formats, including DOCX, XLSX, PPTX, HTML, and more.
The Aspose.Imaging for Java API is a comprehensive library that enables developers to manipulate images in Java applications. It provides a wide range of features, such as the ability to render JPEG images to JPEG2000 images. The API also supports a variety of other image formats, including BMP, GIF, TIFF, PNG, and more.
By using the Aspose.PDF for Java and Aspose.Imaging for Java APIs, developers can easily convert an epub file to a JPEG2000 image in Java. Both APIs are part of the Aspose.Total for Java package, which provides a comprehensive set of APIs for working with a variety of file formats in Java applications.
Convert EPUB to JPEG2000 in a Single File via Java
The API also allows you to export EPUB file to JPEG2000 to a single file. In order to convert all pages, you can first render your EPUB 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 EPUB to JPEG2000 With Watermark via Java
Using the API, you can also export EPUB file to JPEG2000 with watermark in your JPEG2000 document. In order to add a watermark to you can first convert EPUB 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 EPUB 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 .
