IOfficeTextShapingProvider

Namespace OfficeIMO.Drawing

Assembly OfficeIMO.Core

Modifiers abstract

Provides externally shaped glyph runs to OfficeIMO renderers without requiring a shaping-engine dependency.

Remarks

A host can adapt HarfBuzz, DirectWrite, Core Text, or another shaping engine once and reuse it across PDF and other OfficeIMO renderers. Returning null declines a run and lets the consuming renderer use its dependency-free fallback.

This type appears in these public API surfaces even when no hand-authored example is attached directly to the page.
