Hello -
I'd like to use ginput to extract image coordinates from the cursor on an
image, however ginput is returning 0's.
The image (.jpg) displays fine with imshow or image [the coordinates in
lower left of figure do not change when moving cursor over figure/image]
Ginput does not generate an error, but returns '0' (or '0, 0, -1' if
returning 3 values.)
I am using 3.2.4 on ubuntu 11.10; ginput works fine for regular plots. Same
issue on a wubi/xp 11.1 installation.
Any help/suggestions would be greatly appreciated.
Rob
p.s. I'm relatively novice with ubuntu and have preferred
installations/updates with synaptic or software centre, in that's relevent
[saw a couple older threads re Windows 7 issues but not on ubuntu, or w/
solutions that looked applicable]
