Parameters

  • pageFormat:

    The page format object whose scaling factor you want to set.

  • scale:

Discussion

You can call the function PMSetScale to change the scaling factor that appears when your application invokes the Page Setup dialog.

If you call PMSetScale after calling PMSessionPageSetupDialog, make sure you call PMSessionValidatePageFormat(_:_:_:) before you call PMSessionBeginCGDocument or PMSessionBeginDocument.

If you call this function after initiating a print job, the change is ignored for the current job.
