Hello I dont think we can do this and please correct me if I'm wrong, but I want to scale pixel art without blurring (a Nearest Neighbor scaling method) and currently we can't do this. I don't have room in memory to load super massive versions to scale down either.
More opengl type access would be nice for those of us using pixel art in our games.
I don't believe Corona currently has such low-level access.
However you could always simply scale your images in Photoshop or some other program before loading them into your app.

The problem is that i would have to scale them to be too large in photoshop because currently, only scaling down will maintain pixel art accuracy.
A quick google search yielded code to do the trick in objective-c
Sprite *aSprite = [Sprite spriteWithFile:@"someTextureImage.png"];
[aSprite.texture setAliasTexParameters];
In corona, a nice implementation would add a boolean "antialias" value to the table
--to scale pixelated content
image.antialias = false
--to smooth scale non-pixelated content
image.antialias = true
It would be nice to hear corona's opinion on matters like this.
