Having problems with the image lib and resizing images proportionally.
This is my config:
Code:
$config['image_library'] = 'gd2';
$config['source_image'] = $file_path;
$config['new_image'] = $resize_file_path;
$config['maintain_ratio'] = TRUE;
$config['master_dim'] = 'auto';
$config['width'] = $this->input->get('w');
//$config['height'] = $this->input->get('h');When I do this and resize to 100 width, the width is 100, but the height is the original image size. I thought that maintain_ratio would scale the image proportionally?
I did see this post, but I did not have a image_thumb, so not appropriate.

I almost want to do all the the new with/height logic myself, but feel it really should be built in.

Try changing $config['master_dim'] from 'auto' to 'width';

Tried that, $config['master_dim'] = 'width'; gives the same result.

Try setting height property to some small number, here is an example of what worked for me:
Code:
$config['image_library'] = 'gd2';
$config['source_image'] = $source_image;
$config['new_image'] = $new_image;
$config['maintain_ratio'] = TRUE;
$config['master_dim'] = 'width';
$config['width'] = $width;
$config['height'] = 100;
$this->image_lib->initialize($config);Image resize problems - El Forum - 08-26-2008

Nice one steelaz, that worked.
Is that really how it is intended to work? Seems to me that if i wanted to fit an image proportionally into a certain width all i would need is the width and maintain_ratio.
I might have to extended the image lib to make it a little easier to scale images.
