property Options: TRenderOptions;
Set of rendering hints such as LCD optimization, annotations, grayscale rendering, and smoothing control
reInvert ve reNightDuotone; her sayfa tile'ı işlendikten sonra ve katmanlar boyanmadan önce uygulanan, yalnızca TPdfView'a özgü son-işlem düşük görme dönüşümleridir
reNightDuotone uses NightDuotoneInk and NightDuotonePaper; when both reInvert and reNightDuotone are set, reInvert takes precedence
Active := TruePdfView1.Pdf at runtime, re-apply any view-only settings because the new TPdf has its own state
begin
PdfView1.Options := PdfView1.Options + [reNightDuotone];
PdfView1.NightDuotoneInk := $0000C8FF;
PdfView1.Active := True;
end;
