Convert pnm to fpx

What is the difference between .pnm and .fpx?

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 FPX (FlashPix Bitmap Image File) format is a type of image file designed to support high-resolution photographs and images. Developed in the mid-1990s by a consortium including Kodak, Microsoft, Hewlett-Packard, and Live Picture Inc., the FPX format is based on the Image Content Architecture (ICA), which allows it to store multiple resolutions of an image within a single file. This makes it especially useful for efficiently viewing and editing images without requiring the full image file.
