Convert K25 to PBM

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 PBM (Portable Bitmap) file extension, part of the Netpbm project, originated in the late 1980s to facilitate efficient and portable graphics file interchange. Primarily, PBM files are used to store monochrome bitmaps in a simple ASCII text format, ensuring easy compatibility across different systems and platforms. This format supports only black-and-white imagery, making it particularly useful in scenarios where simplicity and minimalism are prioritized, such as in Unix environments for bitmap manipulation and transfer. Its historical significance lies in promoting a standardized approach to bitmap graphics in early computer technology.
