Convert JNG to RAS

The JPEG Network Graphics (JNG) file extension is designed for storing JPEG-encoded image data within the PNG file format. Introduced as part of the MNG (Multiple-image Network Graphics) format, JNG was created to provide a flexible, high-quality image format that supports both lossy and lossless compression. It is particularly useful in applications requiring the integration of JPEG compression within a wider range of data types and multimedia elements. Though not widely adopted, JNG offers enhanced compatibility and versatility for complex imaging tasks in computer graphics and web development.

The Sun Raster file extension, also known as RAS, is a bitmap graphics file format developed by Sun Microsystems for use on their SunOS operating system. It supports black-and-white, grayscale, and color images with various pixel depths and includes simple Run-Length Encoding (RLE) compression. The format was widely used in UNIX-based systems and is supported by many imaging applications. The RAS format has largely been superseded by more modern formats but remains relevant for legacy systems and specific use cases.
