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 +\fBpamsumm\fP reads a Netpbm image (PNM or PAM) and performs a +summary function over all the samples in all the rows, columns, and planes +and prints the result to Standard Output. +.PP +\fBpamsumm\fP performs the operation on the actual sample values. In the +case of a PGM or PPM or PAM equivalent (i.e. a visual image), this is not the +same as the light intensities represented by those samples. See the format +specifications of +.BR "PGM" (1)\c +\&, +.BR "PPM" (1)\c +\&, and +.BR "PAM" (1)\c +\&, for the precise +meanings of samples in these formats. If you want to do arithmetic on light +intensities of such a visual image, you can use \fBpnmgamma\fP to convert it +to one with samples proportional to light intensity, and then +use \fBpamsumm\fP on the result. +.PP +If you want to summarize by column (e.g. add up the columns +separately), use \fBpamsummcol\fP. If you want to summarize by row, +use a combination of \fBpamsummcol\fP and \fBpamflip\fP. If you +want to summarize a particular plane, use \fBpamchannel\fP to +extract it and then \fBpamsumm\fP. + + +.UN options +.SH OPTIONS +.PP +In addition to the options common to all programs based on libnetpbm +(most notably \fB-quiet\fP, see +.UR index.html#commonoptions + Common Options +.UE +\&), \fBpamsumm\fP recognizes the following +command line options: +.PP +You must specify exactly one of \fB-sum\fP, \fB-mean\fP, +\fB-min\fP, or \fB-max\fP. + + +.TP +\fB-sum\fP +.sp +This option makes the summary function addition. + +.TP +\fB-mean\fP +.sp +This option makes the summary function arithmetic mean. + +.TP +\fB-min\fP +.sp +This option makes the summary function arithmetic minimum. + +.TP +\fB-max\fP +.sp +This option makes the summary function arithmetic maximum. + +.TP +\fB-normalize\fP +.sp +This option causes each sample to be normalized to a fraction + (in the range 0..1) so the result is independent of the image's + maxval. E.g. if you request the mean of an image which has maxval + 200 and all the samples have value 50, \fBpamsumm\fP will give you + 50 as an answer. But \fBpamsumm -normalize\fP will give you .25. +.sp +If instead you want a result that is independent of maxval but still + in integers, you can use \fBpamdepth\fP to convert the input to some + standard maxval and not use \fB-normalize\fP.
