Declarationproperty DrawOuter: Boolean;
If True, the unselected layers are drawn as "grayed". The current layer is drawn normally.
Note: Only the current layer
is shown as ungrayed. All other layers, even if there are multiple selected layers, are grayed out.
Examples// Grey areas outside of current layer
ImageEnView1.CurrentLayer.DrawOuter := True;
// Enable DrawOuter for all layers
ImageEnView1.LayersSetProperties( LYR_ALL_LAYERS, IELP_DrawOuter, True );
