Convert DPX to PPM

The DPX (Digital Picture Exchange) 2.0 file format is a widely adopted standard for exchanging high-quality, resolution-independent, pixel-based images, primarily used in the film and post-production industries. Developed by the Society of Motion Picture and Television Engineers (SMPTE), DPX files store individual frames of scanned film or digital images, supporting both color and grayscale data. Introduced in 1994 and updated to version 2.0, DPX facilitates the transfer of digital images for film recording and digital cinema projection, ensuring consistent image quality across different platforms and devices.

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.
