Convert EPUB to APNG via Java
Export EPUB file to APNG within any within any Java J2SE, J2EE, J2ME applications without using Adobe® Acrobat Reader
Converting an epub file to an APNG 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 the epub file to a JPEG image. The second step is to use the Aspose.Imaging for Java Image Processing API to render the JPEG image to an APNG image.
The Aspose.PDF for Java API is a powerful library that enables you to manipulate PDF documents in various ways. It allows you to convert PDF documents to other file formats, such as JPEG, PNG, and TIFF. It also enables you to extract text, images, and other content from PDF documents.
The Aspose.Imaging for Java Image Processing API is a comprehensive library that provides a wide range of image processing capabilities. It allows you to manipulate images in various ways, such as resizing, cropping, rotating, and flipping. It also enables you to convert images from one format to another, such as JPEG to APNG.
By combining the capabilities of the Aspose.PDF for Java and Aspose.Imaging for Java APIs, you can easily convert an epub file to an APNG image in Java. This process is simple and efficient, and it can be completed in just two steps. With the Aspose.Total for Java package, you can access both of these powerful APIs and take advantage of their comprehensive image processing capabilities.
Convert EPUB to APNG in a Single File via Java
The API also allows you to export EPUB file to APNG 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 APNG. 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 APNG format using save method.
Convert EPUB to APNG With Watermark via Java
Using the API, you can also export EPUB file to APNG with watermark in your APNG 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 APNG format.
Convert & Rotate EPUB to APNG File via Java
Using the API, you can also rotate the output APNG 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 .
