SYNOPSIS

10       pnmstitch  [ [left_filespec] right_filespec | left_filespec right_file‐
11       spec output_filespec ] [-width=width] [-height=height] [-xrightpos=col‐
12       umn]   [-yrightpos=row]  [-stitcher={RotateSliver,  BiLinearSliver,Lin‐
13       earSliver}]    [-filter={LineAtATime,HorizontalCrop}]     [-output=out‐
14       put_filespec] [-verbose]
15
16       All  options  can  be abbreviated to their shortest unique prefix.  You
17       may use two hyphens instead of one.  You may separate  an  option  name
18       and its value with white space instead of an equals sign.

DESCRIPTION

22       This program is part of Netpbm(1).
23
24       pnmstitch  stitches  together two panoramic photographs.  This means if
25       you have photographs of the left and right side of  something  that  is
26       too  big  for  a  single camera frame, pnmstitch can join them into one
27       wide picture.
28
29       pnmstitch works only on side-by-side images, not top and bottom (though
30       you  could  certainly  use  pamflip  in  combination  with pnmstitch to
31       achieve this).  It stitches together two images, but  you  can  use  it
32       repeatedly to stitch together as many as you need to.
33
34       Your  photographs  must overlap in order for pnmstitch to work, and the
35       overlap should be substantial.   pnmstitch  shifts  and  stretches  the
36       right hand image to match it up the left hand image.  You probably want
37       to crop the result with pamcut to make a nice rectangular image.
38
39       If you're just trying to join (concatenate) two images at their  edges,
40       use pnmcat.
41
42       The  left_filespec  and right_filespec arguments are the specifications
43       (names) of the PNM files  containing  the  left  hand  and  right  hand
44       images.   If you specify only right_filespec, the left hand image comes
45       from Standard Input.  If you specify neither,  both  images  come  from
46       Standard Input as a multi-image file containing first the left and then
47       the right image.
48
49       output_filespec is the specification (name) of  the  output  PNM  file.
50       The  -output option also specifies the output file.  You cannot specify
51       both the argument and the option.  If you specify neither,  the  output
52       goes to Standard Output.

OPTIONS

57       -width=width
58
59       -height=height
60
61       -xrightpos=column
62
63       -yrightpos=row
64              These  are  constraints  on  where pnmstitch stitches the images
65              together.  For the LinearSliver method, column and row tell what
66              location  in  the  right  hand image matches up to the top right
67              corner of the left hand image.
68
69
70       -stitcher={RotateSliver,BiLinearSliver,
71              LinearSliver} The default is RotateSliver.
72
73
74       -filter={LineAtATime,HorizontalCrop}
75              No details available.
76
77
78       -output=output_filespec
79              Name of output file.  If you don't specify this option, the out‐
80              put image goes to Standard Output.
81
82
83       -verbose
84              This option causes pnmstitch to issue messages to Standard Error
85              about the stitching process.
