pfm: the PFM graphic image file format as understood by the Netpbm; Examples of ppm files in various formats

Feb 27, 2024 · This document describes the PFM graphic image file format as understood by the Netpbm converters pamtopfm and pfmtopam. There are multiple similar formats known as PFM in the world, none of them authoritatively documented.

PFM Portable FloatMap Image Format The Portable FloatMap format was designed as a floating-point image format in the spirit of Jef Poskanzer 's Portable Pixmap file format from the PBMPlus toolkit, most currently available through the Source Forge NetPBM distribution.

Pfm (or Portable FloatMap) image format stores image as floating point pixels and hence are not restricted to usual 0-255 pixel value range. This is useful for HDR images or images that describes something other than colors like depth. One …

The PFM (Portable Floatmap) is a simple structured raster image format part of Netpbm converters. It supports both color and grayscale images.

Feb 24, 2025 · 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.

May 17, 2024 · A Portable Float Map (PFM) file is a specialized type of file used primarily in computer graphics and simulations to store grayscale images or height maps. Here’s a breakdown of what it is...

Dec 1, 2024 · Portable Float Map (PFM): This is a simple, floating-point grayscale image format primarily used for high-dynamic-range imaging. Printer Font Metrics (PFM): This kind of PFM file contains font metric data used by printers and operating systems to render fonts correctly.

This document describes the PFM graphic image file format as understood by the Netpbm converters pamtopfm(1)and pfmtopam(1). There are multiple similar formats known as PFM in the world, none of them authoritatively documented.

The Portable FloatMap (PFM) file format is a lesser-known yet critically important image format, especially in fields that require high fidelity and precision in image data. Unlike more common formats like JPEG or PNG that are designed for general use and web graphics, the PFM format is specifically engineered to store and handle high-dynamic ...
