Follow-up Comment #16, bug #48667 (project octave):
I've downloaded the latest code and compiled. I certainly prefer this
behavior, as I'm sure many will like this.
There are a couple issues when I try the first set of commands in the original
post:
1) In gnuplot graphics toolkit the color
>> get(gca, 'colormap')
ans =
1 0 0
0 1 0
is coming out as binary black and white rather than red-green. That seems
like something I need to fix in gnuplot script functions. Should I open a new
bug report for that, or just attach a patch file here?
2) When I switch to 'fltk' graphics toolkit, the GUI command line output
freezes here:
>> graphics_toolkit ('fltk')
>> demo('image', 1);
image example 1:
clf;
colormap (jet (21));
img = 1 ./ hilb (11);
x = y = -5:5;
subplot (2,2,1);
h = image (x, y, img);
ylabel ("limits = [-5.5, 5.5]");
title ("image (x, y, img)");
subplot (2,2,2);
h = image (-x, y, img);
title ("image (-x, y, img)");
subplot (2,2,3);
h = image (x, -y, img);
title ("image (x, -y, img)");
ylabel ("limits = [-5.5, 5.5]");
subplot (2,2,4);
h = image (-x, -y, img);
title ("image (-x, -y, img)");
The window will still accept commands and I see a red/green binary image in
the lower-right corner. 'exit' will exit properly as well. It's just that
the keystrokes don't appear in the window.
With the --no-gui option the command line output does not freeze.
