This tells qpdf whether to attempt to + remove unreferenced resources from pages when doing page splitting + operations. Prior to this change, the default was to attempt to + remove unreferenced resources, but this operation was very slow, + especially for large and complex files. The new default is "auto", + which tells qpdf to analyze the file for shared resources. This is + a relatively quick test. If no shared resources are found, then we + don't attempt to remove unreferenced resources, because + unreferenced resources never occur in files without shared + resources. To force qpdf to look for and remove unreferenced + resources, use --remove-unreferenced-resources=yes. The option + --preserve-unreferenced-resources is now a synonym for + --remove-unreferenced-resources=no. + 2020-04-03 Jay Berkenbilt <ejb@ql.org> * Allow qpdf to be built on systems without wchar_t.
