Re: color from txt images

In a direct offline reply to me, Wayne questioned how I import since an
imported text file should open as a 32-bit (float) image. I was properly
importing, however, embarassingly, when this first happened, and
neglecting that it was 32-bit, I incorrectly jumped to the conclusion
that it was RGB - somehow in spite of it being 32-bit and not 24 or
36-bit. Needing 8-bit gray scale, I just got into the habit of
immediately chnaging the mode to 8-bit grayscale every time I imported a
text file and forgot about the problem until I saw the post I replied
to.

Therefore...thanks to Wayne for calling attention to my ovesight and
error, and my apologies to any who caught that and spent any time
pondering it.
