How to change current figure handle?

I want to get image from a handle named axes1 in my code. How can I use gcf to get that image? I tried this but it is not working:

axes(handles.axes1);

train_image=getimage(gcf);

The image I am getting is from another axes(not axes1). Please help.

Do no use gcf or gca for code that you want to work properly. Always obtain, pass, and use graphics handles explicitly for all of your GUI objects.
