Draw doesn't support different page sizes in the same document which causes issues with the import of Visio diagrams. libvisio works around this by generating pages of the largest H and W, but this is not a good solution.
Draw needs to support different page sizes in the same document. It should also, as per visio, support variable sized canvas's which then can be mapped to different paper sizes for printout (on a per page basis.)
See bug https://bugs.freedesktop.org/show_bug.cgi?id=60433 as a reference.
This report is likely covered by bug 49787. It would be good if a developer could confirm if this really is a duplicate or further clarify if there is specific work to be done to Draw / libvisio to otherwise get around this issue i.e., without implementing slide / page styles. Status set to NEEDINFO. Please set back to NEW, once the requested information is provided. Thanks.
