imgbutton

HB = IMGBUTTON(H,CDATA) returns a handle to a uicontrol in parent H where
the two-element cell array CDATA contains image data to indicate the off
and on states of the button.

IMGBUTTON(...,'PROP1',VAL1,'PROP2',VAL2,...) sets the other properties of
the uicontrol.

For some reason, the buttons do not seem to work in uibuttongroups as
expected.

Only works for checkbox, radiobutton and togglebutton styles.

Example:
cdata = {imread('off.png'),imread('on.png')};
hbtn = imgbutton(gcf,cdata,'position',[0 0 50 50]);
