Any way to compress images

[eluser]gvillavizar[/eluser]
Hello,

In my site my users are uploading pictures, I can limit the file size they're uploading. Is there any way for me to reduce the file size from 1mb to, say 250kb?

Thanks for your help.

You can change the quality setting in the image manipulation class: http://ellislab.com/codeigniter/user-gui...e_lib.html

Thanks for your reply. That worked like a charm.

Another question, can I load the library more than once with different properties in the same controller.

Like

Code:

if($photo1)
{
$config['source_image'] = '/images/' . $photo1];
$config['create_thumb'] = FALSE;
$config['maintain_ratio'] = TRUE;
$config['width'] = 330;
$config['height'] = 280;
$config['quality'] = '100%';
                
$this->load->library('image_lib', $config);

$this->image_lib->resize();

}

if($photo2)
{
$config2['source_image'] = '/images/' . $photo2];
$config2['create_thumb'] = FALSE;
$config2['maintain_ratio'] = TRUE;
$config2['width'] = 330;
$config2['height'] = 280;
$config2['quality'] = '100%';
                
$this->load->library('image_lib', $config2);

$this->image_lib->resize();

}

Don't load it more than once.
Use

Code:

$this->image_lib->clear();
$this->image_lib->initialize($config2);

The user guide states:

The clear function resets all of the values used when processing an image. You will want to call this if you are processing images in a loop.
