PFM (Portable Float Map)


 * "PFM" redirects here. For the font format, see Adobe Type 1.

PFM (Portable FloatMap) is the unofficial floating point Netpbm image format.

Such a format has been invented multiple times, in incompatible ways. The most standard version of it is probably the one supported by Netpbm, which apparently came from the HDR Shop graphics software.
