Are posterize, invert, equalize, and threshold legal to use? They are under adjustments in Photoshop, not in the filters. If applied to the whole image would they be legal in Basic?

Yep, as long as they effect every pixel in the image, these actions are legal :)

Enjoy.

I don't think it's as simple as looking under the adjustment menu -- gradients are listed there as well and a whole thread went back and forth on them a while back, end result wwas they were not legal.

If they change the value of of the layers under them, without having pixel values themselves -- then yes they are legal.

Posterize, equalize, and threshold are effects, and although they are not under the filters menu, they function as such and are illegal in Basic.
Invert is a special case. One can obtain an inverted-color (negative) image quite easily using curves, which is an allowed tool. The invert function (wherever it's located in the various software packages) is also legal in Basic, if applied to the whole image.

you can posterize using curves as well.
