Options property

Set of rendering hints such as LCD optimization, annotations, grayscale rendering, and smoothing control

reInvert and reNightDuotone are TPdfView-only post-render low-vision transforms applied after each page tile is rendered and before overlays are painted

reNightDuotone uses NightDuotoneInk and NightDuotonePaper; when both reInvert and reNightDuotone are set, reInvert takes precedence

• Set design-time defaults in the Object Inspector or assign at runtime before Active := True
• Low-vision options repaint the viewer and do not change the underlying PDF document
• If you replace PdfView1.Pdf at runtime, re-apply any view-only settings because the new TPdf has its own state
