You may separate an option +name and its value with white space instead of an equals sign. + +.UN description +.SH DESCRIPTION +.PP +This program is part of +.BR "Netpbm" (1)\c +\&. +.PP +\fBpamtopfm\fP reads a Netpbm image (PNM or PAM) and converts it +to a PFM (Portable Float Map) image. +.PP +The PFM (Portable Float Map) image format is a lot like PPM, but uses +floating point numbers with no maxval to achieve a High Dynamic Range +(HDR) format. That means it doesn't have a concept of absolute color +and it can represent generic light intensity information rather than +just visual information like PPM does. For example, two pixels that +are so close in intensity that the human eye cannot tell them apart +are not visually distinct, so a visual image format such as PPM would +have no reason to use different sample values for them. But an HDR format +would. +.PP +There are details of the PFM format in the +.BR "PFM +Format Description" (5)\c +\&. +.PP +.UR http://www.debevec.org/HDRShop +USC's HDRShop program +.UE +\& and a program called Lefty use it. + +\fBpamtopfm\fP creates a color PFM image if its input is RGB (PPM) +and a non-color PFM otherwise. +.PP +Use +.BR "\fBpfmtopam\fP" (1)\c +\& to convert a PFM +image to Netpbm format. + + +.UN options +.SH OPTIONS + + +.TP +\fB-scale=\fP\fIfloat\fP +.sp +This specifies the scale factor of the PFM image. + Scale factor is a component of the PFM format. + Default is 1.0. + +.TP +\fB-endian=\fP{\fBbig\fP|\fBlittle\fP} +.sp +This specifies the endianness of the PFM image. The samples + in the raster of a PFM image are 4 byte IEEE floating point + numbers. A parameter of the IEEE format, and therefore the PFM + format, is endianness, i.e. whether the specified bytes are + ordered from low addresses to high addresses or vice versa. +.sp +\fBbig\fP means big endian -- the natural ordering; + \fBlittle\fP means little-endian, the Intel-friendly ordering. +.sp +Default is whichever endianness the machine on which \fBpamtopfm\fP + runs uses internally, which results in the faster execution. + + + +.UN seealso +.SH SEE ALSO +.BR "Netpbm" (1)\c +\&, +.BR "pfmtopam" (1)\c +\&, +.BR "pam" (5)\c +\& + +.UN history +.SH HISTORY +.PP +\fBpamtopfm\fP was added to Netpbm in Release 10.22 (April 2004). +.SH DOCUMENT SOURCE +This manual page was generated by the Netpbm tool 'makeman' from HTML +source.
