GDI+ Turning off AntiAlias

semhelp

Is there a way to turn off antialiasing? I've tried smoothingmode.none, but
it doesn't help.

I need to draw 2 rectangles (using a hatchbrush) that have some overlap.
I'd like the result to appear as if single polygon was drawn. With the
antialiasing, I get a different result where the rectangles overlap.

Textures such as hatch brushes and texture brushes should respond to the
InterpolationMode settings.

The interpolationmode does have an effect, but there isn't a
"interpolationmode.NONE" setting. The "interpolationmode.nearestneighbor"
setting doesn't completely turn off anitaliasing.

Any other ideas?
