This +means if you have photographs of the left and right side of something +that is too big for a single camera frame, <b>pnmstitch</b> can join them +into one wide picture. + +<p><b>pnmstitch</b> works only on side-by-side images, not top and bottom +(though you could certainly use <b>pnmrotate</b> in combination with +<b>pnmstitch</b> to achieve this). It stitches together two images, but +you can use it repeatedly to stitch together as many as you need to. + +<p>Your photographs must overlap in order for <b>pnmstitch</b> to +work, and the overlap should be substantial. <b>pnmstitch</b> shifts +and stretches the right hand image to match it up the left hand image. +You probably want to crop the result with <b>pamcut</b> to make a nice +rectangular image. + +<p>If you're just trying to join (concatenate) two images at their edges, use +<b>pnmcat</b>. + +<p>The <i>left_filespec</i> and <i>right_filespec</i> arguments are the +specifications (names) of the PNM files containing the left hand and +right hand images. If you specify only <i>right_filespec</i>, 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. + +<p><i>output_filespec</i> is the specification (name) of the output PNM file. +The <b>-output</b> 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. + + +<A NAME="lbAE"> </A> +<H2>OPTIONS</H2> + +<DL COMPACT> +<DT><B>-width=<i>width</i></B> +<DT><B>-height=<i>height</i></B> +<DT><B>-xrightpos=<i>column</i></B> +<DT><B>-yrightpos=<i>row</i></B> +<DD> +These are constraints on where <b>pnmstitch</b> stitches the images together. +For the <b>LinearSliver</b> method, <i>column</i> and <i>row</i> tell what +location in the right hand image matches up to the top right corner of the +left hand image. + +<DT><b>-stitcher=</b>{<b>RotateSliver</b>,<b>BiLinearSliver</b>, + <b>LinearSliver</b>} +<DD> +The default is <b>RotateSliver</b>. + +<dt><b>-filter=</b>{<b>LineAtATime</b>,<b>HorizontalCrop</b>} +<DD> +No details available. + +<dt><b>-output=</b><i>output_filespec</i> +<DD> +Name of output file.
