IDWriteTextAnalyzer::AnalyzeLineBreakpoints Method

Analyzes a text range for potential breakpoint opportunities, reading attributes from the source and reporting breakpoint opportunities to the sink callback SetLineBreakpoints.

Syntax

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

Parameter

• analysisSource
  A pointer to the source object to analyze.

• textPosition
  The starting text position within the source object.

• textLength
  The text length to analyze.

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

Rückgabewert

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

Hinweise

Although the function can handle multiple paragraphs, the text range should not arbitrarily split the middle of paragraphs, unless the specified text span is considered a whole unit. Otherwise, the returned properties for the first and last characters will inappropriately allow breaks.
