If the image is already on the display, use the the TVRD() function.
Something like:

IDL> image = tvrd() ; options for size and 24-bit may be included here
IDL> s = size(image) ; get the size of the image array
IDL> intimage = intarr(s(1), s(2)) ; create an int array using sizes
The '*' below allow you to fill the intimage array rather than recreate it
IDL> intimage(*,*) = image(*,*)
IDL> openw, lun, 'im.dat', /get_lun ; open the output file
IDL> writeu, lun, intimage ; write the image to the output file
IDL> free_lun, lun ; free the lun
