Q: Force output colorspace without antialiasing possible?

[GeorgLegato]

I need to know, if and how SD could be parametrized so that no antialiasing (AA) effects will occur by creation.
To remove such AA-effects is possible afterwards but always error-prone and imperfect and therefore not under discussion here.

So, is there any api/diffuser-config to make SD produce flat, sharp edges ? Perfectly, if forced to draw in a 16-color-palette colorspace?!
I tried prompting like "hard edges, contrast" ... but nothing helps against that.
