By a compound page we mean a page which consists of a main textpage and a number of embedded objects, e.g., GIFs. We model a compoundpage as a main page and several component objects. The main page isalways assigned with ID 0. All component pageshave the same size; both the main page size and component object size isfixed, but adjustable through OTcl-bound variables <TT>main_size_</TT>and <TT>comp_size_</TT>, respectively. The number of component objectscan be set using the OTcl-bound variable <TT>num_pages_</TT>.<P>PagePool/CompMath has the following major OTcl methods:<P><BR><BR><P>An example of using PagePool/CompMath is available at /tcl/ex/simple-webcache-comp.tcl.<P><BR><HR><ADDRESS>2003-09-23</ADDRESS></BODY></HTML>⌨️ 快捷键说明
