How to Watermark JP2 File Using Java

A watermark is an essential tool for authors seeking maximum exposure for their work on the internet. Placing a watermark on an image serves not only to identify its source or copyright holder but also to promote its creator. This is because the signature containing the author’s name or the internet resource’s name is distributed alongside a digital copy of the image. Watermarks can take the form of text with a wide range of fonts and can be positioned at the image’s edge. When the watermark is transparent, it doesn’t disrupt viewing. However, if the author or copyright holder wishes to emphasize their name, the watermark may partially overlap the image. In order to watermark JP2 image file, we’ll use Aspose.Imaging for Java API which is a feature-rich, powerful and easy to use image manipulation and conversion API for Java platform. You can download its latest version directly from Maven and install it within your Maven-based project by adding the following configurations to the pom.xml.

Steps to Add Watermark to JP2 via Java

You need the aspose-imaging-version-jdk16.jar to try the following workflow in your own environment.

  • Load JP2 file with Image.load method
  • Create instance of Graphics from the Image
  • Define Font, Brush and Format for watermark text
  • Draw watermark using Graphics.drawString method
  • Save image to disc in JP2 format

  • About Aspose.Imaging for Java API

    Aspose.Imaging API is an image processing solution to create, modify, draw or convert images (photos) within applications. It offers: cross-platform Image processing, including but not limited to conversions between various image formats (including uniform multi-page or multi-frame image processing), modifications such as drawing, working with graphic primitives, transformations (resize, crop, flip&rotate, binarization, grayscale, adjust), advanced image manipulation features (filtering, dithering, masking, deskewing), and memory optimization strategies. It’s a standalone library and does not depend on any software for image operations. One can easily add high-performance image conversion features with native APIs within projects. These are 100% private on-premise APIs and images are processed at your servers.

    JP2 What is JP2 File Format

    JPEG 2000 (JP2) is an image coding system and state-of-the-art image compression standard. Designed, using wavelet technology JPEG 2000 can code lossless content in any quality at once. Moreover, without any substantial penalty in coding efficiency, JPEG 2000 have the capability to access and decode the same content efficaciously into a variety of other resolutions and qualities. The code streams in JPEG 2000 is significantly scalable having regions of interest that provide the facility for spatial random access. Possessing Up to 16384 diverse components with the dimensions in terapixels, and precision that can be high as 38 bits/sample.
