Sintaxis
property Zoom: Double;
Descripción
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.
Notas
- Set design-time defaults in the Object Inspector or assign at runtime before
Active := True.
- Los cambios se propagan al TPdf subyacente solo para las propiedades que afectan al estado persistente (p. ej., Pdf.PageRotation); las propiedades visuales puras permanecen locales a la vista
- If you replace
PdfView1.Pdf at runtime, re-apply any view-only settings — the new TPdf has its own state.
Ejemplo
begin
PdfView1.Zoom := ;
PdfView1.Active := True;
end;
