Image Magik

[deathdeyfer2002]

All-

 

I'm trying to automatically resize all of the images on my webpage.  I currently have them stored in an array.  I can access the array from the following code

 

 

for ($imagecounter = 0; $imagecounter < $pic_count; $imagecounter++)
{
$currentimage = $folder[$imagecounter];
echo "<img src='/Movies/$currentimage' >";
}

 

That goes through all of the images and displays them as pictures.  I wanted to use the function from Imagemagik: mogrify .  From the command line it resized the images without any trouble using the following code

mogrify -resize 200x125 Left1.png

 

I have been trying to incorporate this into PHP to have it do this automatically.  Here is what I tried and it appears to be failing everytime

 

$command = '"mogrify -resize 468.75x200"/home/deathdefyer2002/imageA.jpg
exec($command);

 

 

Please help.

exec('mogrify -resize 468.75x200 /home/deathdefyer2002/imageA.jpg');

 

try that

Thanks for the reply.... Actually just tried that with NO luck.  Any other ideas?

try

 

$command = 'mogrify -resize 468.75x200 /home/deathdefyer2002/imageA.jpg';
$output = exec($command);
var_dump($output);

 

and tell us what you see

When I reload the page, It seems to be loading for a little bit but nothing new is being displayed. 

 

I entered

exec('mogrify -resize 468.75x200  /home/deathdefyer2002/imageA.jpg');

 

I am testing the code by using the following:

 

echo "<img src='/home/deathdefyer2002/imageA.jpg' >";

 

Every refresh and the image never changes.

Sorry I overlooked the "CODE" part in the last posing.

 

 

When I run the code I get

 

string(0) ""

[rajivgonsalves]

try this out

 

$command = 'mogrify -resize 468.75x200 /home/deathdefyer2002/imageA.jpg';
$output = array();
exec($command, $output);
var_dump($output);

 

also this

 

echo "<img src='/home/deathdefyer2002/imageA.jpg' >";

 

is that the right path, it should a http path and not your linux path

 

 

[deathdeyfer2002]

I went ahead and updated the code and I still receive the following output string(0) ""

 

 

The Imgsrc line appears to be working just fine.  It IS displaying the image, but with the original dimensions.  If I run the mogrify command on the command line and refesh the page, it does change the resolution.    If you beleive that the IMG SRC could be the problem, then I will go ahead and update that to the HTML path.

not too sure, but could be a permission issue as your php script will run as restricted user you might even want to change the command to a absolute path like for example

 

$command = '/usr/bin/mogrify -resize 468.75x200 /home/deathdefyer2002/imageA.jpg';

 

the above is just an example your command could be located at a different location, you can find the location on the shell by typing

 

which mogrify

 

hope its helpful

that should show you the full path of the command.

Also, you just need one size parameter when doing resize imagemagick can figure the rest out and resize nicely!

 

you should also place your file name in single quotes:

 

Try this:

$command = "mogrify -resize x200 '/home/deathdefyer2002/imageA.jpg'"
shell_exec($command);

I went ahead and updated the path to the file.  That didn't help at all.  I also changed the resolution to X200.  Also this didn't do anything.  Any other suggestions?

[rajivgonsalves]

the only thing i could suggest is to add these lines on top of your script and see if any errors are outputted not too sure how helpful it would be

 

ini_set('display_errors', '1');
error_reporting(E_ALL);

[deathdeyfer2002]

I added that and I get a BUNCH of the following error repeated over and over again

 

 

Notice: Undefined index: quantity in /var/www/webfiles/Movies/Movies1.php on line 159

[rajivgonsalves]

Yes it would show you alot of errors do you have any errors pertaining to that exec function ?

[deathdeyfer2002]

Nope just that error over and over again
