Convert pnm to pgx

What is the difference between .pnm and .pgx?

Description: 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.; The PGX file format is associated with Hopedot VOS, a virtual operating system software that allows users to run a separate operating environment on their computers, similar to virtualization technologies. A PGX file typically contains data related to the Hopedot VOS environment, such as settings, applications, and other user-specific information.
