I was having similar problems resizing the original and creating a thumbnail.
I tried $this->image_lib->clear(); and $this->image_lib->initialize($config); but still had problems until I renamed the $config array.
Code:
// SNIP ----------
$this->load->library('image_lib');
print('about to create THUMBNAIL of ' . $this->photos_dir . $filename . '<br />');
$this->create_thumbnail($this->photos_dir . $filename);
print('about to resize ' . $this->photos_dir . $filename . '<br />');
$this->resize_image($this->photos_dir . $filename);
// SNIP -----------
// RESIZE IMAGE * * * * * * * * * * * * * * * * * * * * *
function resize_image($filepath) {
// configure the ORIGINAL IMAGE
$orig['image_library'] = 'gd2';
$orig['source_image'] = $filepath;
$orig['width'] = $orig['height'] = '600';
$orig['master_dim'] = 'width';
$orig['maintain_ratio'] = TRUE;
$orig['create_thumb'] = FALSE;
// load image manipulation class
$this->image_lib->clear();
$this->image_lib->initialize($orig);
// resize original
if ( ! $this->image_lib->resize()) {
print($this->image_lib->display_errors().'<br />');
return TRUE;
} else {
print('original image resized<br />');
return FALSE;
}
}
// CREATE THUMBNAIL * * * * * * * * * * * * * * * * * * * * *
function create_thumbnail($filepath) {
// configure the THUMBNAIL IMAGE
$config['image_library'] = 'gd2';
$config['source_image'] = $filepath;
$config['width'] = $config['height'] = '160';
$config['master_dim'] = 'width';
$config['maintain_ratio'] = TRUE;
$config['create_thumb'] = TRUE;
// load image manipulation class
$this->image_lib->clear();
$this->image_lib->initialize($config);
// resize thumbnail image
if ( ! $this->image_lib->resize()) {
print($this->image_lib->display_errors().'<br />');
return TRUE;
} else {
print('thumbnail created<br />');
return FALSE;
}
}
This finally worked for me.
I agree that the example in the docs should be a little more explicit about initialize();
