Thread Subject: imshow problem

Hi all,

I have a problem about how to show the name of the image on top of the
window of the figure while using IMSHOW command.

the image showed but there is just this 'Figure 1' on top of the
image, how can I write the name of the image instead on top?

Thanks in advance.
Sophia.

Sophia:

% Enlarge figure to full screen.
set(gcf, 'units','normalized','outerposition',[0 0 1 1]);
% Rename figure title bar.
set(gcf,'name','Demo by ImageAnalyst','numbertitle','off')

You could put any string variable in place of 'Demo by ImageAnalyst'
if you want, such as the filename of the image you displayed.

Hi Sophia,

After imshow use the 'set' command to set the name of the figure. E.g.

>> set(gca, 'Name', 'My Figure Name');

Thanks a lot for helping, but I have some questions about SET
command.
In SET what does gcf do? I searched it in MATLAB help it says :

GCF Get handle to current figure.

What does it mean?

I didn't find anything for these variables:
'units','normalized','outerposition',[0 0 1 1]
What's their use?and what do they mean?

Sorry for asking too much. I just want to understand this command
better.

It would be very nice of you if you help me again.

Thanks in advance.
Sophia.

Are you being sarcastic? It didn't help. It couldn't because axes
does not have a name property. I didn't think it did so I tried and
got this error:
Error using hg.axes/set
The name 'Name' is not an accessible property for an instance of class
'axes'.
You will have to do it the way I said, not the way Jomar says, and
that is to use gcf NOT gca.

Sophia:
gcf is the handle to the current (i.e. last used) figure window.
Look under "Figure properties" in the help for a list of properties
held by the "figure" class.

It helped just for introducing me the SET command(as you said),
otherwise I used what you've said, complete and without any errors. :)

Thank you, I think now it's more comprehensive for me :)
