That's not the kind of modification I was suggesting for imshow.  I

was suggesting this much simpler change (pseudocode):

  if (length (size (image)) == 3 && size (image, 3) == 4)

    show image(:, :, 1:3)

  else

    show image

  endif

I can only see the point of this behaviour if 'imread' actually returns

NxMx3 arrays.

Aaarghh, I of course ment to write MxNx4 here...

That brings us back around to my original post.  I have examples of png files for which

  im = imread ("file.png");

  size (im, 3)

produces the output 4.  The command

  imshow (im(:, :, 1:3))

is a perfectly nice color image.
