[Octave-bug-tracker] [bug #30509] 'imshow' doesn't reverse 'ydir' of axis

[Rik]

Update of bug #30509 (project octave):

                  Status:                    None => Need Info

Follow-up Comment #2:

The 'ydir' property was specifically changed so that images and plots could
be overlaid using 'hold on'.  

The original bug report for that (#30033) has more information.

It would be interesting to see how Matlab handles these issues.  If you have
access to Matlab could you try the following:

plot(1:100,'c');
hold on;
get (gca, 'ydir')
imshow ("arrow_up.jpg");
get (gca, 'ydir')

What this should show is a cyan line from the lower left to the upper right
and the image of an arrow pointing to the top of the screen.  The file
"arrow_up.jpg" is attached to the bug report.

(file #21031)
