引用

IACore.dll
IALoader.dll
IAWinFX.dll
Microsoft.Ink.Analysis.dll
Microsoft.Ink.dll
System.Windows.Interactivity.dll

关键代码

通过RecognizeCommand获得StrokeCollection，笔画集合

    
        
            
        
    
    
        
            8
            8
            #707070
            Rectangle
            True
        
    

使用InkAnalyzer得到预测多个结果

Stroke stroke = GetCombinedStore(strokes);

using (InkAnalyzer analyzer = new InkAnalyzer())
{
    analyzer.AddStroke(stroke, ChsLanguageId);
    analyzer.SetStrokeType(stroke, StrokeType.Writing);

    AnalysisStatus status = analyzer.Analyze();

    if (status.Successful)
    {
        foreach (string item in analyzer.GetAlternates().OfType().Select(x => x.RecognizedString).ToArray())
            if (Alternates.Count < MAX_Alternates_COUNT)
                Alternates.Add(new AlternateViewModel(this,item));
    }
}
