Convert CUR to J2C

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 J2C file extension stands for JPEG 2000 Code Stream, a format defined in Part 1 of the JPEG 2000 standard. Developed by the Joint Photographic Experts Group (JPEG) from 1997 to 2000, J2C files utilize wavelet-based compression, supporting both lossy and lossless compression. This format is primarily used for high-quality image storage and transmission, offering superior compression efficiency and flexibility compared to the original JPEG standard. J2C files are often embedded within other file formats like JP2 for enhanced metadata support.
