  • Default zoom
    This is the zoom level used when a document is opened. It does not alter the
    PDF in any way.
  • Override initial zoom
    When enabled, Infix will ignore any initial-zoom suggestion contained within the PDF and use the Default Zoom specified above.
  • Initial View/Zoom/Page
    Use these options to affect the way the current PDF is displayed when opened in Infix or any other PDF viewer. You will need to save the PDF again in order for any changes made here to become permanent.
