Is there a function or action I can create that will allow me to take an indexed image and limit the pixels in the horizontal plane. For example if I want to limit the pixels to a minimum of four pixels in the horizontal at all times in all used colors and not allowing any less than four pixels connecting is that a possibility? So it would have no stray one pixels, two, or three pixels but only sections of four pixels in every color at all times.

There is no good way to do that in Photoshop.
You'd almost have to write your own separate image processing code to make that work (or your own RGB -> indexed converter).

Sounds almost like you're trying to create a custom weave pattern (like for a jacard loom).

Chris,

Excellent guess at the end there. Thank you for your answer. I was sure it was a long shot at best. This forum is such an excellent resource.
