Convert cff to pnm

What is the difference between .cff and .pnm?

Description: The Common File Format (CFF) is a standardized file structure designed to facilitate the sharing, exchange, and preservation of data across various platforms and applications. It is not tied to a specific domain but is rather a generic format that can be adopted by different types of software and systems for a wide range of data types. The CFF aims to provide a common framework that ensures data interoperability and accessibility, making it easier for users to work with data across different tools without the need for extensive conversions.; The PNM (Portable Any Map Image) file format is a subset of the broader Netpbm format, designed for storing various types of digital images. It acts as an umbrella term for three specific types of grayscale, color, and black-and-white images, represented by PBM (Portable Bitmap), PGM (Portable Graymap), and PPM (Portable Pixmap) formats respectively. PNM files are known for their simplicity and ease of conversion to other image formats.
