SpreadFitting enum

How a page spread is fitted into the available viewport.

Controls whether pages are letterboxed, cropped to fill, or use an adaptive algorithm that selects the best strategy per spread.

Platform availability:

• Android: not exposed; Android always uses a fit-within-width strategy.
• iOS: supported via PSPDFConfigurationBuilder.spreadFitting. Use IOSViewConfiguration.spreadFitting to set this option.
• Web: partially supported; pass via WebViewConfiguration as needed.

No empty space is shown, but parts of the page may be clipped.

adaptive → const SpreadFitting

Let the SDK automatically choose between fit and fill per spread.

Typically selects fill for portrait single pages and fit for landscape or double-page spreads.
