IDWriteTextAnalysisSource::GetNumberSubstitution Method

Gets the number substitution from the text range affected by the text analysis.

Syntax

virtual HRESULT GetNumberSubstitution(
  UINT32 textPosition,
  [out]  UINT32 *textLength,
  [out]  IDWriteNumberSubstitution **numberSubstitution
) = 0;

Parameter

• textPosition
  The starting position from which to report.

• textLength [out]
  Contains the length of the text, in characters, remaining in the text range up to the next differing number substitution.

• numberSubstitution [out]
  Contains an address of a pointer to an object, which was created with IDWriteFactory::CreateNumberSubstitution, that holds the appropriate digits and numeric punctuation for a given locale.

Rückgabewert

Ist Methode erfolgreich, wird "S_OK" zurückgegeben. Andernfalls wird ein HRESULT-Fehlercode zurückgegeben.

Hinweise

Any implementation should return the number substitution with an incremented reference count, and the analysis will release when finished with it (either before the next call or before it returns). However, the sink callback may hold onto it after that.
