+.SH DESCRIPTION
+.sp
+.LP
+The \fBpostmd\fR filter reads a series of floating point numbers from
+\fIfile\fRs, translates them into a PostScript gray scale image, and writes the
+results on the standard output. In a typical application, the numbers might be
+the elements of a large matrix, written in row major order, while the printed
+image could help locate patterns in the matrix. If no \fIfile\fRs are
+specified, or if \fB-\fR is one of the input \fIfile\fRs, the standard input is
+read.
+.SH OPTIONS

+The following options are supported:

+Packs the bitmap in the output file using \fInum\fR byte patterns. A value of
+\fB0\fR turns off all packing of the output file. By default, \fInum\fR is
+\fB6\fR.

+\fB\fB-c\fR \fInum\fR\fR

+.RE
+
+.sp

+\fB\fB-d\fR \fIdimen\fR\fR
+.ad
+.RS 13n
+.rt  
+Sets the default matrix dimensions for all input \fIfile\fRs to \fIdimen\fR.
+The \fIdimen\fR string can be given as \fIrows\fR or \fIrows\fR\fBx\fR
+\fIcolumns\fR. If \fIcolumns\fR is omitted it will be set to rows. By default,
+\fBpostmd\fR assumes each matrix is square and sets the number of rows and
+columns to the square root of the number of elements in each input file.

+.sp

+\fB\fB-g\fR \fIlist\fR\fR

+.rt  
+\fIlist\fR is a comma- or space-separated string of integers, each lying
+between 0 and 255 inclusive, that assigns PostScript gray scales to the regions
+of the real line selected by the \fB-i\fR option. 255 corresponds to white, and
+0, to black. The \fBpostmd\fR filter assigns a default gray scale that omits
+white (that is, 255)  and gets darker as the regions move from left to right
+along the real line.
+.RE
+
+.sp
+.ne 2
+.mk
+.na
+\fB\fB-i\fR \fIlist\fR\fR
+.ad
+.RS 13n
+.rt  
+\fIlist\fR is a comma-, space-, or slash(\fB/\fR)-separated string of  \fIN\fR
+floating point numbers that partition the real line into 2\fIN\fR+1 regions.
+The \fIlist\fR must be given in increasing numerical order. The partitions are
+used  to map floating point numbers read from the input \fIfile\fRs into gray
+scale integers that are either assigned automatically by \fBpostmd\fR or
+arbitrarily selected using the \fB-g\fR option. The default interval \fIlist\fR
+is \fB-1,0,1\fR, which partions the real line into seven regions.

+about the origin which, by default, is located at the center of each page. The

+.RE

+.mk

+\fB\fB-n\fR \fInum\fR\fR
+.ad
+.RS 13n
+.rt  
+Prints \fInum\fR logical pages on each piece of paper, where \fInum\fR can be
+any positive integer. By default, \fInum\fR is set to  \fB1\fR.
+.RE
+
+.sp

+.mk
+.na
+\fB\fB-o\fR \fIlist\fR\fR
+.ad
+.RS 13n
+.rt  
+Prints pages whose numbers are given in the comma separated \fIlist\fR. The
+list contains single numbers \fIN\fR and ranges \fIN1 \fR- \fIN2\fR. A missing
+\fIN1\fR means the lowest numbered page, a missing \fIN2\fR means the highest.
+The page range is an expression of logical pages rather than physical sheets of
+paper. For example, if you are printing two logical pages to a sheet, and you
+specified a range of \fB4\fR, then two sheets of paper would print, containing
+four page layouts. If you specified a page range of \fB3-4\fR, when requesting
+two logical pages to a sheet; then \fIonly\fR page 3 and page 4 layouts would
+print, and they would appear on one physical sheet of paper.

+\fIwindow\fR is a comma- or space-separated list of four positive integers that
+select the upper left and lower right corners of a submatrix from each of the
+input \fIfiles\fR. Row and column indices start at \fB1\fR in the upper left
+corner and the numbers in the input \fIfile\fRs are assumed to be written in
+row major order. By default, the entire matrix is displayed.

+.rt  
+Translates the origin \fInum\fR inches along the positive x axis. The default
+coordinate system has the origin fixed at the center of the page, with positive
+x to the right and positive y up the page. Positive \fInum\fR moves everything
+right. The default offset is  \fB0\fR inches.

+\fInum\fR moves everything up the page. The default offset is  \fB0\fR.
+.RE
+
+.sp
+.LP
+Only one matrix is displayed on each logical page, and each of the input
+\fIfile\fRs must contain complete descriptions of exactly one matrix. Matrix
+elements are floating point numbers  arranged in row major order in each input
+file. White space, including newlines,  is not used to determine matrix
+dimensions. By default, \fBpostmd\fR assumes each matrix is square and sets the
+number of rows and columns to the square root of the number of elements in the
+input file. Supplying default dimensions on the command line with the \fB-d\fR
+option overrides this default behavior, and in that case the dimensions apply
+to all input \fIfile\fRs.
+.sp
+.LP
+An optional header can be supplied with each input file and is used to set the
+matrix dimensions,  the partition of the real line,  the gray scale map, and a
+window into the matrix. The header consists of keyword/value pairs, each on a
+separate line. It begins on the first line of each input file and ends with the
+first unrecognized string, which should be the first matrix element. Values set
+in the header take precedence,  but apply only to the current input file.
+Recognized header keywords are \fBdimension\fR, \fBinterval\fR,
+\fBgrayscale\fR, and \fBwindow\fR. The syntax of the value string that follows
+each keyword  parallels what is accepted by the \fB-d\fR, \fB-i\fR, \fB-g\fR,
+and \fB-w\fR options.
+.SH EXAMPLES
+.LP
+\fBExample 1 \fRGenerating an interval list
+.sp
+.LP
+For example, suppose \fIfile\fR initially contains the 1000 numbers in a 20x50
+matrix. Then you can produce exactly the same output by completing three steps.
+
+.RS +4
+.TP
+1.
+First, issue the following command line:
+.sp
+.in +2
+.nf
+example% \fBpostmd -d20x50 -i"-100 100" -g0,128,254,128,0 file\fR
+.fi
+.in -2
+.sp
+
+.RE
+.RS +4
+.TP
+2.
+Second, prepend the following header to \fBfile\fR:
+.sp
+.in +2
+.nf
+example% \fBpostmd -d20x50 -i"\(mi100 100" -g0,128,254,128,0 file\fR
+.fi
+.in -2
+.sp
+
+.RE
+.RS +4
+.TP

+Third, issue the following command line:
+.sp
+.in +2
+.nf
+example% \fBpostmd file\fR
+.fi
+.in -2
+.sp
+
+.RE
+.sp
+.LP
+The interval list partitions the real line into five regions and the gray scale
+list maps numbers less than -100 or greater than 100 into 0 (that is, black),
+numbers equal to -100 or 100 into 128 (that is, 50 percent black), and numbers
+between -100 and 100 into 254 (that is, almost white).

+.SH NOTES
+.sp
+.LP
+The largest matrix that can be adequately displayed is a function of the
+interval and gray scale lists, the printer resolution, and the paper size. A
+600 by 600 matrix is an optimistic upper bound for a two element interval list
+(that is, five regions) using 8.5 by 11 inch paper on a 300 dpi printer.
+.sp
+.LP
+Using white (that is, 255) in a gray scale list  is not recommended and won't
+show up in  the legend and bar graph that \fBpostmd\fR displays below each
+image.
