Image Lib: How to maintain_ratio with MINIMUM short side?

[eluser]Sven Delle[/eluser]
1. I have a thumbnail slot of 32 by 32 pixels
2. I will create thumbnails from both horizontal and vertical images
3. I need to maintain aspect ratio

How do I make sure I don't end up with white space in the thumbnails?

Scenario:
Image: width: 431 pixels, height: 600

Code:

$config['maintain_ratio'] = TRUE;
$config['master_dim'] = 'auto';
$config['width'] = 32;
$config['height'] = 32;

This gives me an image with a height of 32 and a width of ONLY 23.

How do I make sure that I always FILL the whole thumbnail slot wether the image is horizontal or vertical?

You need to use the crop function.

Grab the image dimensions from the upload class and use them to calculate the coordinates needed for cropping.

Take a quick look at http://www.matmoo.com/digital-dribble/co...image_moo/

It's saved me a load of time when dealing with the Image Library in CI...

Thanks, I'm going for the native CI image lib. And I do not want cropping. I'll see what I can come up with.
