Properly scaling pixel art with lwjgl and slcik-util

[Jumbosize]

Hello,

I have come across a small dilemma with scaling images. I am loading my images pretty much exactly how it is shown the Ninja Cave tutorial (http://lwjgl.org/wiki/index.php?title=Slick-Util_Library_-_Part_1_-_Loading_Images_for_LWJGL).  The problem is this method automatically applies anti aliasing (I believe that's what it is, right?) to the images. Since I'm making a pixel art with quite small images that need to be heavily scaled up, this is a pretty big deal. Pixel art is supposed to be very sharp.

Is there a way to make the images scale up crisply without blurring? Thanks in advance.

The proper term for the "blurring" of an image when stretched is called interpolation.

Unless you want it to look pixelated when zoomed up (which it sounds like you don't want either), you are stuck with two options:
1) Make the images larger so they don't stretch.
2) Create a pixel shader that does what you want to the image when it is stretched.

EDIT: If you do just want to get rid of the blurriness, then use the TextureLoader.getTexture() overload that takes a filter and pass in GL11.GL_NEAREST as the value.

I'm pretty sure he just wants to use GL_NEAREST. That's all you need to get good pixel art.
