macro / formula UI

[wunderer]

hi everybody,

the colleagues from "imageJ" provide a macro/formula UI, where you may enter manipulation formulas for the image
e.g. for the pixel value "v" a formula like this: if ((v>99) && (v<200)) v=v/2+155
- the result "v" is automatically truncated to 0 ... 255.
- this UI also handles other variables like pixel-xyz, width, height,...

wouldn't this be something for xnview as well?
or is it already available, and I simply overlooked it?

cheers, wunderer
