Convert PIX to PPM

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 Portable Pixmap (PPM) file extension, an image format within the Netpbm family, stores simple, uncompressed images. Introduced in the late 1980s, PPM supports RGB color and grayscale images, making it suitable for basic image processing and conversion tasks. Its plain text encoding simplifies debugging and data manipulation, although its lack of compression results in larger file sizes compared to modern formats. As such, PPM finds limited use in contemporary applications, mainly in educational and experimental settings where ease of implementation and readability are prioritized.
