I've just started messing around with Kha and was wondering if there was any way to turn off antialiasing for fonts?

I'm using a size 16 font and rendering at an integer position, but the text is still blurred as shown below. Any help would be greatly appreciated.

I think, that there may be few different reasons for such blur.

In some cases it may be controlled by OS, but most probably it's not our case.
It may be somehow corellated with textue sampler interpolation technique, that samples pixels at the center of pixel (at 0.5x, 0.5y coord, for example), so that UV coords passed to sampler must take it into account.

Most probably, as far as i see, it's result of how fonts managed in Kha. When you load new font, tool, named Kravur creates font texture. And then during render process function getBakedQuad() takes small quad for each rendered character. It's part of optimization for render process. Therefore we have multiple points, where font can be resized and resampled.

Please, note, that i'm not very familiar with Kha, so my statements may be completely wrong.

One possible solution, that I see, to achieve pixel-perfect fonts - is to bake your font into texture, for example with this online tool: http://kvazars.com/littera/
And then adopt graphics2 internals to use your texture, instead of loading from *.ttf

kravur isn't currently used but Kha does basically the same thing at runtime. Some blurriness is to be expected when rendering ttf files and Kha doesn't do super-high-end font-rendering (no subpixel antialiasing for example). Turning off antialiasing is also generally a very bad idea with ttf fonts, you will likely have actual holes in your fonts. When you want super-shard pixely fonts especially at very small sizes you are better off using actual bitmap fonts.
All that said, when asking about font sharpness please provide a sample project. Most people who complained about blurry fonts actually messed up with render targets and texture filtering while I was babbling along about font rendering details.

I've uploaded an example to github. It's quite likely I just messed something up. I know in other frameworks I've been able to get the crisp pixel fonts. Bitmap fonts would also work for me, so this isn't a big deal at all. Again, I really appreciate all the help.

Aha, this is something special, a ttf font which tries to look pixely. Even Windows very own font viewer makes it look blurry in smaller sizes (though it does profit a lot from sub-pixel anti-aliasing). Better use some good old bitmap font rendering for that, putting this in a ttf renderer is just overcomplicating things.

Cool, that makes sense. Thanks for the help.
