Convert PIX to PJPEG

The PIX file extension stands for Alias/Wavefront Run-Length Encoding (RLE) Image Format. Developed by Alias Systems Corporation (later acquired by Autodesk), it was designed for storing bitmap images in PowerAnimator and Alias 3D software. This format was instrumental in creating high-resolution 3D models and animations for movies and video games in the 1990s. The RLE compression minimized file size without compromising image quality, optimizing performance for graphics-heavy tasks. Although its usage has declined in favor of more versatile formats, PIX played a significant role in the evolution of computer graphics technology.

The PJPEG (Progressive JPEG) is a file extension for images that enhances the standard JPEG format by displaying images in successive waves of increasing detail, improving the user experience during slow network conditions. The JPEG stands for "Joint Photographic Experts Group", the organization that developed the standard in 1992. PJPEG is particularly useful for web applications, as it allows images to appear more quickly and progressively refine in quality, rather than loading from top to bottom like baseline JPEGs.
