PageShadowSize property

Width, in pixels, of the soft shadow drawn around each page in continuous modes

Set to 0 for a flat look or 6+ for a deep Acrobat-style drop shadow

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 them at run time before Active := True
• Changes propagate to the underlying TPdf only for properties that affect persistent state (e.g. Pdf.PageRotation); purely visual properties stay local to the view
• If you replace PdfView1.Pdf at run time, reapply any view-only settings — the new TPdf has its own state
