Image manipulation difficulties - El Forum - 11-03-2010
[eluser]Bram Jetten[/eluser]
I am creating a WYSIWYG-editor ( http://cl.ly/e24d621d45dd6dacb9a7 ). It also has image uploading capability. When uploading small to moderately sized images they are uploaded, resized and copied. However, when I try to upload a really big picture (say 6 MP JPG) it will successfully upload that entire image, but just won't do any of the image manipulations. Does this sound familiar?
Here's the code I'm working with:
Code:
if(!$this->upload->do_upload()) {
echo "Mislukt";
} else {
$imgdata = $this->upload->data();
$afbeelding = $imgdata['file_name'];
$upload_config['source_image'] = $imgdata['full_path'];
$upload_config['width'] = 550;
$upload_config['height'] = 550;
$this->image_lib->initialize($upload_config);
$this->image_lib->resize();
$upload_config['create_thumb'] = true;
$upload_config['thumb_marker'] = "_thumb";
$upload_config['width'] = 100;
$upload_config['height'] = 100;
$this->image_lib->initialize($upload_config);
$this->image_lib->resize();
echo base_url() . "uploads/fotos/" . $afbeelding;

Sounds like memory limit issue.. or you've hit the max execution time. For example resizing ~1M jpeg can easily consume 32M of memory as the processing is done with the raw picture inmemory. So you can imagine how much memory it will need to process 6 meg pic.
If you can, try ImageMagick in the config(and if its installed). Atleast with that it wont use the memory_limit set in PHP.

@cahva
Thanks for the tip! After checking out the error logs I found several entries of the following message:
Code:
[Wed Nov 03 21:47:21 2010] [error] [client 77.250.86.248] PHP Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 11672 bytes) in /var/www/vhosts/bsdewaai.nl/httpdocs/system/libraries/Image_lib.php on line 1157, referer: http://www.bsdewaai.nl/blog/dashboardI do not have access to ImageMagick on this particular server. Is it OK to adjust the memory_limit to a higher value so that it won't get exhausted again? Or should I look for a different solution?

When you get the following error ...
"Allowed memory size of 33554432 bytes exhausted"
... there are two things you can do:
1) Increase the memory_limit in your php.ini file to 64MB (or more if necessary) and restart apache. Let us hope it is not 'mislukt';
2) Define the memory limit in your .htaccess (check the internet about how to do this)
You don't have to change anything in ImageMagick ;-)
Can you notify me if you have a beta version of your wysiwyg editor? I need something like that! (or isn't it open source?) I just need to be able to write in bold and be able to set some big smilies.

Thanks for your help guys. My problem is solved! I ended up setting the memory limit in .htaccess to 64MB.
@Christophe28:
I'm using the following source: http://www.wymeditor.org/. I'm just creating a nicer skin and adding proper image uploading/resizing.
