(Optional) A flag specifying whether the transparency group is isolated. If this flag is true, objects within the group are composited against a fully transparent initial backdrop; if false, they are composited against the group’s backdrop. Default value: false. In the group attributes dictionary for a page, the interpretation of this entry is slightly altered. In the normal case in which the page is imposed directly on the output medium, the page group is effectively isolated and the specified I value is ignored. But if the page is in turn used as an element of some other page, it is treated as if it were a transparency group XObject; the I value is interpreted in the normal way to determine whether the page group is isolated.
