CI's image_lib cropping isn't working properly

[eluser]KeyStroke[/eluser]
Hi,

I'm using a javascript interface to pass the X/Y axis and height/width to CodeIgniter to crop images. I noticed that cropping, for some reason, isn't working properly. It doesn't crop exactly where I want, and it seems to ignore the width I provide.

Note that the following CI code doesn't work:

Code:

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

$image_uri = './resources/images/picture.jpg';


$config['x_aixs'] = $this->input->post('x');
$config['y_axis'] = $this->input->post('y');
$config['source_image'] = $image_uri;
$config['width'] = $this->input->post('w');
$config['height'] = $this->input->post('h');
$config['maintain_ratio'] = TRUE;

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

if( ! $this->image_lib->crop() )
{
    echo $this->image_lib->display_errors();
}

Whereas this native PHP code that I've copied from the javascript cropping library works perfectly fine:

Code:

$targ_w = $targ_h = 150;
$jpeg_quality = 90;

$src = './resources/images/picture.jpg';
$img_r = imagecreatefromjpeg($src);
$dst_r = ImageCreateTrueColor( $targ_w, $targ_h );

imagecopyresampled($dst_r,$img_r,0,0,$_POST['x'],$_POST['y'],
$targ_w,$targ_h,$_POST['w'],$_POST['h']);

header('Content-type: image/jpeg');
imagejpeg($dst_r,null,$jpeg_quality);*/

Any idea what's wrong?

Your help is much appreciated

No idea as to your problem. I've hit on many drawbacks using the native image library. I use class.upload.php from verot.net... It is very good.

I don't see where you are passing your $config array to the image library.

Oh crap, lol. I forgot to include that too. Here's the whole function:

Code:

function crop_image()
{
$this->load->library('image_lib');

$image_uri = './resources/images/picture.jpg';

$config['x_aixs'] = $this->input->post('x');
$config['y_axis'] = $this->input->post('y');
$config['source_image'] = $image_uri;
$config['width'] = $this->input->post('w');
$config['height'] = $this->input->post('h');
$config['maintain_ratio'] = TRUE;

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

if( ! $this->image_lib->crop() )
{
    echo $this->image_lib->display_errors();
}

}

Code:

$config['x_aixs'] = $this->input->post('x');

should read:

Code:

$config['x_axis'] = $this->input->post('x');

axis is spelt incorrectly.

Don't you just hate typoos?

Noooooooooooooo. I can't believe I've overlooked such thing. :'(

I guess it happens when do you too much work.

Thanks a lot TheFuzzy0ne.

Incorrect. It's usually a result of having too much blood in the caffeine stream. More coffee ought to fix it!
