image manipulation class - resize() maintain_ratio - not always! - El Forum - 10-19-2010

Hi

I'm re-sizing some images & have set the
$config['maintain_ratio'] = TRUE;

if I set a height value & resize, the aspect ratio is maintained.
However, when I set a width value, then the aspect ratio is NOT maintained.

Here's my code, which is pretty much ripped from the user guide, so nothing complicated:

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

$config['source_image'] = $image;

$config['maintain_ratio'] = TRUE;

$config['height'] = 180;

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

$this->image_lib->resize();

The above works fine.

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

$config['source_image'] = $image;

$config['maintain_ratio'] = TRUE;

$config['width'] = 320;

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

$this->image_lib->resize();

The above doesn't keep aspect ratio.

Anyone else experienced this?
Is it a bug in CI or in the gd2 image lib, or am I not using it properly again?

Cheers

Pete
