resize option flag '^' does not work in PHP?

[SEO]

As it seems the resize option flag '^' does not work within the PHP environment. It does work when the command is executed via SSH shell so it must be related to PHP.

I have tried several commands and right now I am trying the folowing:

exec("convert -size 300x300 ".$image_loc." -thumbnail 100x100^ -gravity center -crop 100x100+0+0 +repage ".$image_loc."");

Is this a bug?

Thanks in advance for your help!

Try enclosing the part of code in " or '

Code: Select all

exec("convert -size 300x300 $image_loc -thumbnail \"100x100^\" -gravity center -crop 100x100+0+0 +repage $image_loc");

or

Code: Select all

exec("convert -size 300x300 $image_loc -thumbnail '100x100^' -gravity center -crop 100x100+0+0 +repage $image_loc");

Thank you for your reply! However, I already tried that and I just used your above examples to try it again and it didn't work.

When I try it in SSH it does work for some reason.

When running my first example on my server at home ( XAMPP on windows XP ) the first example I posted worked. But it will not work on the server my site is on; I have tried escaping the ^ and it still will not work.

I wonder if it is a version problem ?

convert: invalid argument for option `100x100^': -resize.

6.4.0 04/16/08 Q16 at home and 6.3.5 08/29/07 Q16 on my server.

Well, for me the server is already upgraded to the latest version and it does work from shell (SSH). Just not from within PHP.

Do you get the same error as me ?

Code: Select all

echo "<pre>";
$array = array();
exec("convert -size 300x300 $image_loc -resize 100x100^ -gravity center -crop 100x100+0+0 +repage $image_loc 2>&1", $array); 
echo "<pre>";
print_r($array); 
echo "</pre>";

I also tried escaping the ^ with ^ as somebody else had a similar problem and that worked for them but not for me.

I am not seeing any errors, I believe error reporting for exec()/system() calls is disabled for security reasons.

I can not get anything to work; I think you will have to do a bit more work with php:

Code: Select all

<?php

$size = getimagesize( $image_loc );
if ( $size[0] > $size[1] ){
$size = "x100"; }
else { $size = "100x"; }

$cmd = "-size 300x300 $image_loc -resize $size -gravity center -crop 100x100+0+0 +repage";

exec("convert $cmd $image_loc"); 

?>

exec("convert $cmd $image_loc"); 

?> 

Yes, that seems to be a good solution! I will try it!

Thanks a lot for your help!

FYI:

The ^ for resize was added in version 6.3.8-2 according to the changelog

I thought it had been around a lot longer than that. As I said in another post it works at home on 6.4.0 04/16/08 Q16 and not 6.3.5 08/29/07 Q16 on my server, that pressumably is why !

At least there is a simple way around it using a bit more php.

Also note that ^ is a special character for Windows batch scripts. It may not work as expected for PHP on a windows box.
