Presently, cpdf will include the input structure tree in each output PDF. To remove a structure tree entirely, preprocess the file with \texttt{-remove-dict-entry /StructTreeRoot}. If you do not require structure trees, this will lead to faster splitting, and smaller outputs. The \texttt{-process-struct-trees} option will trim the structure tree (the data which forms the logical structure of the PDF). In its absence, the structure tree is preserved wholesale in each output file.
