2006-05-05 Alexander Larsson <alexl@redhat.com> * gtk/gtkprintoperation-unix.c: Implement per-page paper sizes. * gtk/gtkprintoperation.c: Implement per-page paper sizes for pdf output. Make gtk_print_operation_set_pdf_target() work again * tests/Makefile.am: * tests/testprint.c: * tests/testprintfileoperation.[ch]: Add more test code for printing support. This tests per-page paper sizes & orientation and deriving from GtkPrintOperation.
