Pixel Resize Tutorial

[Lavalevel]

Hey guys, last night I was searching around for how to create and resize some pixel stuff! I cobbled together this technique and figured I should do a tutorial on it.
You guys I assume are all old pros and I don't know how useless this method is, but it works great for me.

You can do this in Photoshop, just make sure the piece is in indexed mode. Might be faster since you never have to switch programs.

What you have to do in Photoshop is go to: Image > Image Size..., change the Resample Method to Nearest Neighbour and change pixels to percentage and (i quoute myself from another post) "remember to enlarge in hundreds (Ex: 200%, 300%, 400%, etc...), if not it's not gonna be faithful. When you enlarge by 500% a pixel turns into 25 (5x5)".

In GraphicsGale:

All Frames -> Resample
*Enter new dimensions* (not Dr-Who-style... well you can if you want...)
Untick "Smooth"
OK

Bahahar, he vector traces it first! That actually works? Thomas Knoll wants to slap you. Kidding, Lava. Welcome to this place. And thanks so much for taking the time to post this.


But like Jorund said, just scale it up the correct percentage and with the right interpolation setting. It only truly works in increments of 100%. Behold:

Notice how when you scale in increments of 100% you're simply adding the original's width and height to itself each time. This way you get a pure and non-destructive enlargement. There's no way to non-destructively downscale pixel art.


Now your way offers infinite size possibilities since you convert it to vector (which I'd default to Illustrator for) but it inevitably muddles the pixels since you're not using the above stated formula. This is a scaled up crop of your blog's final resultant image:

Also this might be helpful for people using Photoshop:

Go to Preferences > General, set Image Interpolation to Nearest Neighbor. Now whenever you distort, rotate, whatever something there wont be automatic anti aliasing and such.

I found this tool pretty interesting: http://info.sonicretro.org/RotSprite
