>I naively wanted to use the drawing tools to
>fill in the value of a masked region of a 32-bit
>image: select the value using the picker, fill
>in the area with the fill bucket.
>
>When I tried it, I realized my naivite: the
>picker is a ColorPicker and only sees the
>look-up-table values, so the REAL values can't
>be picked and filled, at least not for non-color
>images.
>
>Of course, there are more difficult ways around
>this problem - create a mask, manipulate the
>mask, apply the manipulated mask - but it seems
>like the straight-forward way of doing it should
>work.

>Before I attempt to modify ColorPicker and
>Toolbar, I thought I'd ask for simpler solutions
>I haven't thought about.

>No, please don't send me a macro - I know one
>can do it using a dozen lines of ImageJ code.
>The point is that simple standard things
>shouldn't require an extra macro
