NAME

       pnmstitch - stitch together two panoramic (side-by-side) photographs

SYNOPSIS

       pnmstitch   [   [left_filespec]   right_filespec   |   left_filespec   right_filespec  output_filespec  ]
       [-width=width]   [-height=height]    [-xrightpos=column]    [-yrightpos=row]    [-stitcher={RotateSliver,
       BiLinearSliver,LinearSliver}] [-filter={LineAtATime,HorizontalCrop}] [-output=output_filespec] [-verbose]

       All  options can be abbreviated to their shortest unique prefix.  You may use two hyphens instead 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).

       pnmstitch stitches together two panoramic photographs.  This means if you have photographs  of  the  left
       and  right  side of something that is too big for a single camera frame, pnmstitch can join them into one
       wide picture.

       pnmstitch works only on side-by-side images, not top and bottom (though you could certainly  use  pamflip
       in  combination  with  pnmstitch  to  achieve this).  It stitches together two images, but you can use it
       repeatedly to stitch together as many as you need to.

       Your photographs must overlap in order for pnmstitch to work, and  the  overlap  should  be  substantial.
       pnmstitch  shifts  and  stretches  the right hand image to match it up the left hand image.  You probably
       want to crop the result with pamcut to make a nice rectangular image.

       If you're just trying to join (concatenate) two images at their edges, use pamcat.

       The left_filespec and right_filespec arguments are the specifications (names) of the PNM files containing
       the left hand and right hand images.  If you specify only right_filespec, the left hand image comes  from
       Standard  Input.   If  you  specify  neither,  both images come from Standard Input as a multi-image file
       containing first the left and then the right image.

       output_filespec is the specification (name) of the output PNM file.  The -output  option  also  specifies
       the  output  file.   You  cannot  specify  both the argument and the option.  If you specify neither, the
       output goes to Standard Output.

OPTIONS

       In addition to the options common to all programs based on libnetpbm (most notably  -quiet,  see   Common
       Options ), pnmstitch recognizes the following command line options:

       -width=width

       -height=height

       -xrightpos=column

       -yrightpos=row
              These  are  constraints  on  where  pnmstitch  stitches the images together.  For the LinearSliver
              method, column and row tell what location in the right hand image matches  up  to  the  top  right
              corner of the left hand image.

       -stitcher={RotateSliver,BiLinearSliver,
              LinearSliver} The default is RotateSliver.

       -filter={LineAtATime,HorizontalCrop}
              No details available.

       -output=output_filespec
              Name of output file.  If you don't specify this option, the output image goes to Standard Output.

       -verbose
              This option causes pnmstitch to issue messages to Standard Error about the stitching process.
