IDWriteTextAnalyzer::AnalyzeNumberSubstitution method

Analyzes a text range for spans where number substitution is applicable, reading attributes from the source and reporting substitutable ranges to the sink callback SetNumberSubstitution.

Syntax

C++


virtual HRESULT AnalyzeNumberSubstitution(
   IDWriteTextAnalysisSource * analysisSource,
   UINT32                     textPosition,
   UINT32                     textLength,
   IDWriteTextAnalysisSink   * analysisSink
) = 0;

Parameters

analysisSource

Type: IDWriteTextAnalysisSource*

The source object to analyze.

textPosition

Type: UINT32

The starting position within the source object.

textLength

Type: UINT32

The length to analyze.

analysisSink

Type: IDWriteTextAnalysisSink*

A pointer to the sink callback object that receives the text analysis.

Return value

Type: HRESULT

If this method succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.

Remarks

Although the function can handle multiple ranges of differing number substitutions, the text ranges should not arbitrarily split the middle of numbers. Otherwise, it will treat the numbers separately and will not translate any intervening punctuation.
