Convert K25 to PGM

The K25 file extension stands for Kodak DC25 Digital Camera Raw Image. It is a proprietary format used by the Kodak DC25 digital camera, introduced in the mid-1990s. K25 files store unprocessed image data directly from the camera's sensor, preserving high image quality and allowing extensive post-processing. This format was pivotal in early digital photography, enabling users to manipulate images without significant quality loss.

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.
