[SOLVED] Problems using image lib in a loop - El Forum - 11-11-2010

[eluser]Mr. Pickle[/eluser]
I'm having problems using the image_lib in a loop.

Description:
I have a folder with several image files.
I loop all the image files within a folder to copy them (with new dimensions) to a different directory.

Therefor I use the image_lib with which you have to set the settings (such as source file, dimensions and destination file) in a config array and pass them to the image lib.

This is my code for that part:

Code:
$config['image_library']= 'gd2';

$config['source_image'] = $dir . $file;

$config['create_thumb'] = FALSE;

$config['maintain_ratio'] = TRUE;

$config['width']     = 1024;

$config['height']     = 768;

$config['new_image']     = $this->config->item('photo_dir') . strtolower($file);

$this->load->library('image_lib', $config);

Next thing is that I do the resize action:

Code:
$this->image_lib->resize();

After this I clear the image_lib:

Code:
$this->image_lib->clear();

My problem
The image lib is still using the config from the first loop as I only get the first image (name) with the last image content in my destination folder.

Found the solution, I had to (re)initialize the image_lib:

First, just call the image_lib without config outside the loop.
After this within the loop I set the settings config for the loop and have the image_lib first cleared and then re-initialized with the settings for that loop.

So outside the loop:

Code:
$this->load->library('image_lib');

And within the loop:

Code:
// Set all the configs

$config['key'] = 'value';

// Clear to be sure

$this->image_lib->clear();

// Initialize

$this->image_lib->initialize($config);

// Resize

$this->image_lib->resize();
