You're question kinda lack context so sorry if my answer doesn't help.

The option you're looking for could be named something like: 

- interpolation: none 

 - (min|max)_filter: nearest

-  crisp-edges

- pixelated

- nearest-neighbor

- optimize-contrast // this one is the weirdest O.o

 depending on software/framework/engine/library you use.

e.g. in opengl it is:

glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_NEAREST);
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_NEAREST);
