## NAME
       pfmtopam - Convert PFM (Portable Float Map) image to Netpbm format


## SYNOPSIS
       **pfmtopam **[**-maxval=_**n_] [**-verbose**] [_imagefile_]

       All  options can be abbreviated to their shortest unique prefix.  You may use two hyphens in‐
       stead of one.  You may separate an option name and its value with white space instead  of  an
       equals sign.


## DESCRIPTION
       This program is part of [**Netpbm**(1)](https://www.chedong.com/phpMan.php/man/Netpbm/1/markdown).

       **pfmtopam **reads a PFM (Portable Float Map) image and converts it to PAM.

       See [**pamtopfm**(1)](https://www.chedong.com/phpMan.php/man/pamtopfm/1/markdown) for a description of PFM.

       If you want one of the older, more portable Netpbm formats, run the output through **pamtopnm**.

       **pamtopfm  **creates  a PAM with tuple type "RGB" or "GRAYSCALE" depending on whether or not the
       PFM is in the color subformat.

       Use [**pamtopfm**(1)](https://www.chedong.com/phpMan.php/man/pamtopfm/1/markdown) to convert a PFM image to Netpbm format.



## OPTIONS
       In addition to the options common to all programs based on libnetpbm  (most  notably  **-quiet**,
       see ]8;;index.html#commonoptions\ Common Options]8;;\ ), **pfmtopam **recognizes the following command line options:



### -maxval=_

              This specifies the maxval for the PAM.  Default is 255.


### -verbose

              This causes **pfmtopam **to display messages describing
                   the PFM input file.
