Display only a part of jpg without cropping the actual file

[Bonzo]

You would have to save this ( untested code ) as a file on its own and call from the page with <img src="code.php">

Code: Select all

<?php
$cmd = "convert image.jpg -gravity Center -crop 100x100+0+0  JPG:-";

header("Content-type: image/jpeg");
passthru($cmd, $retval);
?>

As to doing it without IM, I assume you could do it with Javascript

If you are not doing this for the web, but for a X window display use...

convert image -crop ???? miff:- | display

I very often use this to look at the results of various transformations, debugging, and trial and error option determination, without saving the resultingj image to disk.
