Thank you. I fixed it.

Now faced with another question -
How get geocoordinates from full image to zoom?

For zoom widget I have geocoordinates of center point only (latitude and longitude). How to use geocoordinates for central point to get geocoordinates for all zoomed region

Guess I need use CONVERT_COORDS function, but how to do it by correct way ?

If i did so, as shown below i've got coordinates [-180;-90] [180;90]

PRO doMoveZoom,event
WIDGET_CONTROL,event.top,GET_UVALUE=pState
x=event.x
y=event.y
print,"Coordinates in zoom widget =",x,y

IF ((*pState).zoomLoaded NE 0) THEN BEGIN
data=*(*pState).pzoomImage
;geocoordinates central pixel
zoom_coords=*(*pState).zoom_coords
value=data[x,y]
print,"Coordinates in zoom widget=",x,y,value," Central geo_point=",zoom_coords
; How to use geocoordinates for central point
;to get geocoordinates for all zoomed region ?
D = CONVERT_COORD(x,y,/DEVICE,/TO_DATA)
ENDIF
...

Thanks
