Convert RAF to PBM

The RAF file extension stands for Fujifilm Raw Image File, a format used by Fujifilm digital cameras to store uncompressed image data directly from the camera's sensor. Introduced to preserve maximum image quality, RAF files contain minimally processed data, allowing for extensive post-processing flexibility. This format, based on the TIFF/EP standard, includes metadata such as camera settings and format version. RAF files are primarily utilized by professional photographers and enthusiasts for high-quality image editing and archiving.

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.
