How to get image data from an axes

Hello.

I want to get the data from an image displayed on an axes using GUIDE. I have searched this forum and found that using the following should work

IM=get(handles.axes1, 'CData');

However i get the following error

Error using hg.axes/get
The name 'CData' is not an accessible property for an instance of class 'axes'.

Error in SingleImageSNR>pushbuttonCentre_Callback (line 1846)
IM=get(handles.axes1, 'CData');
