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,Horizontal-
Crop}] [-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, pnm-
stitch can join them into one wide picture.
pnmstitch works only on side-by-side images, not top and bottom (though you could cer-
tainly 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 pnmcat.
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
-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 stitch-
ing process.
