PHP - convert tif to jpg and resize using ImageMagick
I am using ImageMagick 6.7.1-7, installed on a Linux server. I have a tif image that needs to be converted to jpg and then resized to a thumbnail.
Here is the code I have so far:
No image is being returned. I am showing an error code of 1, but no error message (empty array). Any ideas how to fix this?
Here is the code I have so far:
$url = "/home/notie0/public_html/images/models/highres/231/";
$thumb_file = $url . 'thumbs/sample.jpg';
$tiff_file = $url . 'sample.tif';
$IM_path = '/usr/bin/';
$out=array();
$err = 0;
$run = exec($IM_path.'convert $tiff_file -resize 70x100 -quality 70 $thumb_file',$out,$err);
print_r($out);
print_r($err);No image is being returned. I am showing an error code of 1, but no error message (empty array). Any ideas how to fix this?
I guess my first idea would be to load the TIFF image into Photoshop and save it in a more commonly used format. A Photoshop "action" could be used to convert a library if you have more than one TIFF file. Or you might try some of the techniques described here:

After you have converted the TIFF to another format (I recommend PNG because it is not a "lossy" compression) it is easy to create a thumbnail in PHP. Would you be OK with the GD library functions for this part of the process?

Was able to solve this on my own. Although the experts had some great suggestions, none of them directly solved the problem.
<?php
$exec = "convert /path/to/file.tiff /path/to/file.jpg";
