It is widely used in medical imaging, digital cinema, and archival applications, with support in tools like Kakadu, OpenJPEG, and Adobe Photoshop. The format employs wavelet-based compression, supports multiple color spaces, and includes advanced features like region-of-interest coding, progressive decoding, and metadata embedding for enhanced flexibility and scalability.
