[Pantxo Diribarne]

Update of bug #54640 (project octave):

                  Status:                    None => Invalid                
             Open/Closed:                    Open => Closed

Follow-up Comment #2:

The top corner is at [197 1] *not* [1 197] ([x y], y axis is reversed and thus
starts at the top, also see the coordinates at the bottom of the figure window
when you hover it with your mouse cursor).

Simply use 

triangle_corners = fliplr ([ 1 197 ; 313 1 ; 311 389 ]);
corners = fliplr ([ 1 197 ; 313 1 ; 311 389 ]);
...


And you'll obtain the expected result which is that the image is stretched.

Closing report as invalid.
