Convert PDF to APNG via Java
Export PDF file to APNG within any within any Java J2SE, J2EE, J2ME applications without using Adobe® Acrobat Reader
Converting a PDF file to an APNG image in Java is a simple two-step process. The first step is to use the Aspose.PDF for Java API to export the PDF file to a JPEG image. This API is part of the Aspose.Total for Java package, which provides a comprehensive set of APIs for manipulating and converting various file formats.
Once the PDF file has been converted to a JPEG image, the second step is to use the Aspose.Imaging for Java API to render the JPEG image to an APNG image. This API provides a wide range of image processing capabilities, including the ability to render images in various formats. It also provides a number of features for manipulating and editing images, such as resizing, cropping, and rotating.
By using the Aspose.PDF for Java and Aspose.Imaging for Java APIs, you can easily convert a PDF file to an APNG image in Java. The process is straightforward and requires minimal coding. Furthermore, the Aspose.Total for Java package provides a comprehensive set of APIs for manipulating and converting various file formats, making it an ideal choice for developers who need to work with different file types.
Convert PDF to APNG in a Single File via Java
The API also allows you to export PDF file to APNG to a single file. In order to convert all pages, you can first render your PDF 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 PDF to APNG With Watermark via Java
Using the API, you can also export PDF file to APNG with watermark in your APNG document. In order to add a watermark to you can first convert PDF 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 PDF 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 .
