how to use TextureCoordinates to generate a mask image?

[walemmlis]

Hello,

Is it possible to use TexCoord node to generate the following mask?
By default, both U and V is in the range (0, 1).
In the following mask, U will be 0 in the left 50% of the image. And will be 1 in the middle from 50% to 80%. And 0 again in the right 20 percent.
V is not used in this case.

I know SphereMask can do something similar, but, it’s interesting t to know how to do this without using SphereMask.
