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


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.


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 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.


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.
LinearSliver} The default is RotateSliver.
No details available.
Name of output file. If you don't specify this option, the output image goes to Standard Output.
This option causes pnmstitch to issue messages to Standard Error about the stitching process.

This program was added to Netpbm in Release 10.7 (August 2002).

"Breadth. Circle. Desert. Monarch. Month. Wisdom. (for which there are
No rhymes)" was just the title, and I only read that far.

That was because I felt like some old agent-of-the-Czar
When a plotter swims within the scope of his exertions,
And I was scared this hothead would start hedging his assertions
Before I had him dead-to-rights. (A Chekan's or a SMERSHian's
Lot, you know, is not a happy one.) He might retract.

A liar is a liar is a liar. That's his act.
But six distinct demonstrable defiances-of-fact
Before he hits line one? That's taking aim at the World's Record.
I wanted this quark-colored tangerine-flake double-deckered
Omnibus of absurdities to make it to the checkered
Flag. He started fast, but could he forge on? Was he s e r i o u s?

He had the Grand Prix style all right. Intense. Composed. Imperious.
And lies to burn. Poor lies, in no wise deep or deleterious.
He drove them home like thumb (or rather tooth nail fist and chin) tacks.
He planted Cosmic Glints to make you whimper for a glint-axe.
"Unconstellated words rain down...inexorable syntax"
Etcetera Etcetera.

It's not that I'd set up,
Like Carrie Nation beating back the drunkard from his cup,
To scourge the world of liars. I'd as soon be Offissa Pup.
I'd sooner hassle fetishists and call myself a bra-narc.

If I were Lord of All (or even constitutional monarch)
I'd send a Deluge down, with one-way tickets on the Non-ark
For lying priests and pedagogues. They make a feller's fez hurt.
But whom does Keats's whopper about corpulent Cortez hurt?
Or any poet's whopper? If he wants to say the Desert
Is made of pea-green camambert, hell, welcome to the circle.

We listen to a Bard the way a certain kind of jerk'll
Listen to the leaves or listen to a percolator perkle.
As long as he can grind em out, a dozen-or-so a month,
We'll praise him to the nth degree, and to the n-plus-1th.
He could have called the thing "Fifth. Sixth. Eighth. Ninth. Twelfth.
Baker's dozenth"
For all we care. We'll cheer him to the w-x-y-zedth
As long as his flimflammeries have brio and have breadth
And don't come on like nursery-nannies pushing early to bedth
To three-year-olds with jingles about Health and Wealth and Wisdom.

He should look out though. He might take himself in, and that is dumb.

Do that, and sure as malheur is the better part of Msdom,
Sententiousness will sidle in with snapshots in his wallet
To lay a little something on us camels: some small strawlet
Of Wisdom, say, or Beauty. Take this poem now. I call it
"Width. Rhombus. (see Lozenge.) Glacier. Despot. Fortnight. Bilge."
I t o l d myself: "No overkill. Go easy on the bilge."
But then. T u e u r is human. And what rhymes with bilge is bilge.
