Convert DPX to PGM

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 Graymap (PGM) file extension, originating in the late 1980s as part of the Netpbm project, stands for "Portable Gray Map". It serves as a simple, versatile format for grayscale images, enabling easy reading and writing by various programs. Due to its straightforward structure and plain text encoding, it's often used in academic and research settings where ease of parsing and accessibility are crucial. PGM files store grayscale images in a compact, efficient manner, making them an essential tool for image processing tasks.
