Ah, I see now that

  image ([0, 1], [0.49, 62.5], [1:64; 1:64])

works, so I guess this is a problem with displaying images that have only one row or column.

I think the cause of this problem is that things like

  image ([0, 1], [0.49, 62.5], 1:64)

are not working correctly now with the fltk backend.  Using the gnuplot backend, this generates a rainbow image (with the spectrum determined by the current colormap).  With the fltk backend, the image is apparently not displayed.

hello,
I noticed that in fltk backended octave(3.3.52+) a colorbar is not shown correctly(it shows frame only). The colorbar of ver 3.3.52(fltk backend) works well in my environment.

% colorbar test
imagesc(rand(8))
colorbar
