I'm designing some things related to retro video-games. Part of these involving having blown-up game sprites. When I rip them from games, they are obviously microscopic (usually 16x16 px or so), scaling in Photoshop makes them all blurry due to something built-in. How do I do just a straight scale? It's annoying to have to copy past into another app just to scale something.

They are small low resolution images and you can't make them larger without them looking as you describe.

What I mean is, I want to blow up a 1x1 red pixel to be 16x16 (as in 16 red pixels by 16 red pixels), without photoshop blurring it up. Right now the "workaround" I have is using Graphic Converter, which is obviously not what I'd like to do.

Hi mrtickles, welcome to the forum firstly.

Secondly. I fear you may be misunderstanding either the capabilities or the designation of Photoshop. I have provided some links in case they help:

http://en.wikipedia.org/wiki/Anti-aliasing

http://en.wikipedia.org/wiki/Aliasing

http://www.fredmiranda.com/SI/index.html

I could go on with links, but in my view, what you are asking is about aliasing, in essence.

What I'm asking is how to turn anti-aliasing off when scaling graphics so I don't have to use another program to do so.

I don't know if this is what you mean but you can change the interpolation in the General Preferences, by all accounts if enlarging pictures go with Bi-Cubic Sharper, even if enlarging (this goes against the Adobe recommendation)

In case any of you are still wondering how to do this, in the "Image Size" dialog, select "nearest neighbor" from the drop-down menu...
