Image interpolation mode in Chrome/Safari?
I need to have an image render with nearest-neighbor resizing and not the bicubic way that is currently used. I currently use the following:
ms-interpolation-mode: nearest-neighbor;
image-rendering: -moz-crisp-edges;
This works in IE and Firefox, but not in Chrome and Safari. Are there any webkit alternatives or any other way to achieve this effect?
Answer
Edit: It's now possible with image-rendering: -webkit-optimize-contrast;.

This doesn't work in current versions of Chrome, here are some useful links:

- Image scaling by CSS: is there a webkit alternative for -moz-crisp-edges?
I didn't think there was a way.
And some quick Googling all but confirms it; the top Google result for webkit image interpolation is:

Reported in September 2008, and still not resolved.

If I needed this, I'd probably write a PHP script to dynamically scale images up using nearest neighbour.
This will work in every browser, but then you have all that extra processing and transfer overhead.
