Try this:
ivolume, /test, view_grid=[2, 1]
id = itGetCurrent(tool=otool)
vol_id = otool->findIdentifiers('*data_space/volume', /visualizations)
ovol = otool->getByIdentifier(vol_id)
; this bit sets up an image plane
ops_id = otool->findIdentifiers('*imageplane*', /operations)
result = otool->doAction(ops_id)
planeId = otool->findIdentifiers('*image plane*', /vis)
oimplane = otool->getByIdentifier(planeId)
oimplane->setProperty, orientation=2
; now grab the data for the image plane
oSelVis = oTool->GetSelectedItems(count=nSelVis)
oData = oSelVis->GetParameter('IMAGEPIXELS')
strToolID = IDLitSys_CreateTool('Image Tool', /view_next,
initial_data=oData, $
visualization_type='IMAGE')
oNewTool = oTool->GetByIdentifier(strToolID)
oCreateVis = oNewTool->GetService("CREATE_VISUALIZATION")
oParmSet = OBJ_NEW('IDLitParameterSet', $
DESCRIPTION='Image Plane', NAME='Image Plane',$
TYPE='Image', ICON='image')
; hook up the plane data
oParmSet->Add, oData, PARAMETER_NAME='IMAGEPIXELS', /PRESERVE_LOCATION
oCommandSet = oCreateVis->CreateVisualization(oParmSet, 'IMAGE')
