Convert CUR to J2K

The CUR file extension, short for Cursor Image, is a format used in Microsoft Windows for cursor icons. Its primary use is to display and manage custom cursor images, enhancing user interaction with graphical user interfaces. CUR files, a variant of ICO files, were introduced in early versions of Windows to enable animated and static cursor designs, elevating visual and functional user experiences. The structure typically contains image data, including multiple resolutions and color depths, which ensures adaptability across various display settings in Windows environments.

The J2K file extension stands for JPEG 2000 Code Stream Syntax, a part of the JPEG 2000 standard developed by the Joint Photographic Experts Group (JPEG). Introduced in 2000, JPEG 2000 offers superior image compression and quality compared to the original JPEG format. The J2K codestream is highly flexible, supporting both lossy and lossless compression, and allows for scalable decoding, which means images can be efficiently accessed at various resolutions and quality levels. This makes J2K ideal for applications requiring high-quality image storage and transmission, such as medical imaging, digital cinema, and satellite imagery.
