Unable To Successfully Disable Anti-Aliasing

[Paul Ryevere]

Forewarning, it's very possible I'm using incorrect terminology.
Sorry if I am.

I set a very small (64 x 48) image as my wallpaper through Wallpaper engine, and instructed Wallpaper Engine to resize it such that it would fill my monitor by selecting the "center" alignment option in the wallpaper entry's properties pane.

This worked, but in resizing the image, it applied some manner of anti-aliasing, which is undesirable to me.

I tried various things to get Wallpaper Engine to not apply this effect, but had no luck.
So, I searched the discussions, read everything that seemed even remotely relevant and found nothing. Searched around online, and discovered that Wallpaper Engine has a global Anti-Aliasing setting, which I then disabled.

However, when resized to fill my monitor, the effect is obviously still being applied.
So, I removed the wallpaper from my "inventory," made sure the setting was at "None," restarted Wallpaper Engine, double-checked the setting was still "None," re-imported the image I wanted to use, and still, when resized, the image remained blurry.

And I do mean "blurry" to be clear. Not pixelated, but blurry. I want it to be pixelated, with hard, distinct edges.

Anyway, I then removed the image entry in my "inventory," set global post-processing to "Disabled," restarted Wallpaper Engine, re-imported the image again, and, yep, same issue, still being altered beyond simple resizing.

Eventually, I gave up, and just resized the image myself in Photoshop.

While that does solve the problem of "the image isn't being displayed in the way that I want," it doesn't solve the problem of "Wallpaper Engine is seemingly ignoring my settings choices."

So, I am here to ask, is there a different setting which controls this behaviour?
Is this working as intended, or is this a bug?
How can I have Wallpaper Engine display this image in the manner in which I wish, without needing to use an external program to manually resize the image myself in advance?

Screenshots available if desired.
