Introduce zoom-crop in Media image handling

[TwoThirdsWater]

Please could the wordpress image handling introduce support for a zoom crop of images smaller than specified file sizes.

What is the question here? What kind of changed do you need?

If you upload a small image, then request a larger file format (as specified using add_image_size) Wordpress will return a larger image, but not cropped to the ratio specified in add_image_size. As I understand it wordpress does not currently support 'zoom and crop'. This would be a useful function as the current set up can break layouts by returning incorrectly shaped images.

Ah that way. WordPress doesn't do upscaling. In this case I'm not sure what the right solution would be.

At the risk of stating the obvious, a solution would be to enable Wordpress to upscale, or at least add it as a configurable option. Whilst I understand all the arguments about loss of quality, this would be a valuable addition to the image handling set up (and not a hard one to achieve).

You can already enable it by using the link mentioned in that ticket: ​http://wordpress.org/support/topic/wp-351-wp-image-editor-scaling-up-images-does-not-work?replies=3.

Good to know. Many thanks!
