Use to use mogrify to create a thumbnail of an image

[Phil Powell]

[PHP]
$mogResponse = exec("mogrify -size ${width}x$heigh t " .
$this->locationPath . '/' . $this->fileName . '
-resize ' .
$width . "x$height > +profile " .
$this->thumbLocationP ath . '/' . $this->fileName
.. ' 2>&1');
[/PHP]

This attempt at creating a thumbnail only causes the original image to
be resized while creating a "ghost image" in the /thumb folder where
the thumbnail should be.

Could someone show me exactly how to use mogrify to generate a
thumbnail in another folder while keeping the original image intact?

BTW imagecreatetrue color() is not an option in this case because I'm
working with PHP 4.1.2

Thanks
Phil

The answer is to make a copy Phil, then work on that one =)

Maybe not the best code in the world but it does work and maybe useful to
you:


<http://tk.digiserv.net/dLib_IMagick_Si mple.class.phps >


It does little more than what you're asking.. an example:


<?php
require_once('d Lib_IMagick_Sim ple.class.php') ;

$image_filename = 'foo.png';
$image_width = 300; /* Resized width */
$image_height = 240; /* Resized height */
$display_image = false; /* Self explanitory option */
$scaling = true; /* Force size or scale image */
$overwrite_imag e = false; /* Return false or overwrite image */

$img = new IMagick_Simple;
$img->debug(true) /* Optional verbose debugging */

/* Note the following 2 can be the same location */
$img->thumbs_path( '/full/path/to/dir/for/destination/image/');
$img->fullsize_path( '/full/path/to/dir/with/original/image/');

if (!$img->thumb(
$image_filename ,
$image_width,
$image_height,
$display_image,
$scaling,
$overwrite_imag e
)) {
die($img->error_msg()) ; /* Pointless if debug == true */
}
?>


If all goes well, you should have 'foo.png' as your original image and
't_foo.png' as the resized ( / scaled) image.

Some vars above are used unneccessarily. . but there's no docs per-se for
the class.. so hopefully this outlines the usage a little better (although
the debug error msgs do contain the syntax).

If any use.. feel free to do as you wish with the code (re-use / modify
/ use chunks of).. but would be nice to leave the header intact =)

HTH anyway.
