Convert ODG to J2K via Java
Transform ODG into J2K using native Java APIs without needing any image editor or 3rd-party libraries.
How to Convert ODG to J2K Using Java
Converting file formats may seem like a routine task encountered by graphic designers. Yet, underestimating its significance would be a mistake. The evaluation of your work might depend on how swiftly and effectively you tackle this task. Typically, original images need conversion into formats better suited for printing or online publication. If the original image originates from a graphic editor, it might be in vector format. In this scenario, it must be rasterized and converted to a raster format for publishing purposes. You have the choice to save the image in an uncompressed format for optimal quality or convert it to a lossless compressed format to reduce file size. In certain contexts, like web publishing, you can opt for lossy compressed formats. Specially designed algorithms for image data compression permit a significant reduction in file size while preserving acceptable image quality. This facilitates fast image file downloads from the internet. In order to convert ODG to J2K, 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 Convert ODG to J2K via Java
Developers can easily load & convert ODG files to J2K in just a few lines of code.
- Load ODG file with Image.load method
- Create & set the instance of required subclass of ImageOptionsBase (e.g. BmpOptions, PngOptions, etc.)
- Call the Image.save method
- Pass file path with J2K extension & object of ImageOptionsBase class
System Requirements
Before running the conversion example code, make sure that you have the following prerequisites:
- Operating system: Windows or Linux.
- Development environment: Supports .NET Core 7 and higher, such as Microsoft Visual Studio.

ODG What is ODG File Format
The ODG file format is used by Apache OpenOffice's Draw application to store drawing elements as a vector image. It follows the XML based file format specifications outlined by Advancement of Structural Information Standards (OASIS). ODG represents drawings as vector images using points, lines and curves. Besides OpenOffice, LibreOffice and other applications also provide support for working with ODG file format. Other formats supported by OpenOffice, for example, include ODT, ODF, ODP and ODS.
