Convert XBM to JNG

The XBM (X11 Bitmap Graphic) file extension is a plain-text binary file format historically used in the X Window System to store monochrome bitmap images. Its primary use is for defining small, simple graphics such as icons and cursors. Originating from the 1980s, XBM files enable the inclusion of image data directly in C source code, facilitating easy integration and compilation within applications. While their use has declined with the advent of more advanced graphics formats, XBMs remain relevant for legacy systems and specific low-resource environments.

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.
