Image Resizing doesn't work [Solved] - El Forum - 01-14-2011

Hi,
I need some help because I don't understand why the code doesn't resize uploaded images.
Actually I'm using GalleryCMS, so, I have the code to upload them, to create the thumbnail and, after that I added this code to resize:
Code:
function resize($fileName, $ext) {
$mainimage = '../galeria/fotos/'.$fileName.'.'.$ext;
list($width, $height, $type, $attr) = getimagesize($mainimage);
$config['image_library'] = 'GD2';
$config['source_image'] = $mainimage;
$config['create_thumb'] = FALSE;
$config['maintain_ratio'] = TRUE;
$config['width'] = 400;
$config['height'] = 400;
$this->load->library('image_lib', $config);
$this->image_lib->resize();
if(!$this->image_lib->resize()) echo $this->image_lib->display_errors();
}Below the code to upload, I have this too:
Code:
$uploadImage = '../galeria/fotos/'.$newname;
write_file($uploadImage, $file);
$this->_createThumbnail($md5Date, $ext, $thumbWidth, $thumbHeight, $newname, $thumbname);
$this->resize($md5Date, $ext, $thumbWidth, $thumbHeight, $newname, $thumbname);
} else {
$this->load->view('gallery_view');
}Any idea?
Greetings.

Is upload process performed with success?
Is the source_image setting correct?
Why do you call two times the resize method? It's not necessary!
Code:
$this->load->library('image_lib', $config);
if(!$this->image_lib->resize())
echo $this->image_lib->display_errors();Cristian Gilè

Cristian, thank you for your reply.
The upload process and the thumbnail creation works fine. There's no problem with that, so I assume that the source it's ok, because it's the same.
To write the resize process, I followed these instructions: http://ellislab.com/codeigniter/user-guide/libraries/image_lib.html.
Have you have any idea about what's (not) happening?

Hello again,
Luckily I managed to do the resize. What I did was add the code for the resize function inside the thumbnail creation, instead of creating a new function.
The final code looked like this:
Code:
$config['image_library'] = 'GD2';
$config['source_image'] = $mainimage;
$config['create_thumb'] = TRUE;
$config['maintain_ratio'] = true;
$config['master_dim'] = 'width';
$config['width'] = $new_width;
$config['height'] = $new_height;
$config['quality'] = '100%';
$this->load->library('image_lib', $config);
$this->image_lib->resize();
if(!$this->image_lib->resize()) echo $this->image_lib->display_errors();
//Resize
$config['create_thumb'] = FALSE;
$config['width'] = 500;
$config['height'] = 500;
$this->image_lib->initialize($config);
$this->image_lib->resize();
$config['image_library'] = 'GD2';
$config['source_image'] = $t;
$config['create_thumb'] = FALSE;
$config['width'] = $final_width;
$config['height'] = $final_height;
$config['x_axis'] = $to_crop_left;
$config['y_axis'] = $to_crop_top;
$config['maintain_ratio'] = false;
$this->image_lib->initialize($config);
if(!$this->image_lib->crop()) {
echo $this->image_lib->display_errors();
} else {
$this->gallery_tbl->insertImage($_POST['id'], $newname, $thumbname);Thanks again.
