Display precomputed slice object on axes object

Hi there

I am doing some image processing. To visualize my data (on a gui), I use the slice function. Due to the amount of data, I want to precompute the slice plot before displaying it on an axes object. My idea is, to store the precomputed slice plot handle into an variable and display it later on the axes object (which is meanwhile used for other visualization).

The slice object is generated by:

handles.model = slice(x, y, z, imSeq, loc(1), loc(2), loc(3));
hold on;
colormap(gray);
set(handles.model, 'EdgeColor', 'none');
daspect(ratio);
%...
hold off;

In another part of the gui I want display the precomputed slice object:

% is there something like this? =)
set(handles.axesSlice, 'Data', handles.model)

Of course it is possible to add a second axes onto the gui and change the visibility of it, but it would be nice if I can manage it like I am asking for ;-)

Thank you for your reply, Fabian

Thanks for your inf sir

Let me to know how to extract an image from my files into Mat lab to process it

See copyobj()

Note: your slice() routine is going to produce a visible graph unless you specifically make it invisible after your "hold off". And it is going to produce it on whatever the current graphics axis is...

Hi, thanks for your reply.

I played a litte with copyobj. Now my idea was:

unused = axes();
handles.model = slice(x, y, z, imSeq, loc(1), loc(2), loc(3));
% set properties...
delete(unused);

I realized, that this does not work because if I delete the axes the handles.model is not longer a handle (ishandle returns 0). So I can not use it with copyobj (get error "Invalid handle").

This means that I have to store the unused axes too (= second axes object)? I searched for setting axes objects invisible or off, but there seems to be no such property?

set( allchild(unused), 'Visible', 'off')

Or even easier, plop everything into a new figure, and then just set the figure visibility off.
