ιδιότητα Zoom

Zoom factor where 1.0 = 100% (one PDF point = 1 screen pixel at 72 DPI).

Assigning a value implicitly switches FitMode to pfmNone.

All TPdfView display properties trigger a repaint when assigned; you can change several in sequence without flicker because the redraw is coalesced into a single invalidation.

• Set design-time defaults in the Object Inspector or assign at runtime before Active := True.
• Changes propagate to the underlying TPdf only for properties that affect persistent state (e.g. Pdf.PageRotation); pure visual properties stay local to the view.
• If you replace PdfView1.Pdf at runtime, re-apply any view-only settings — the new TPdf has its own state.
