在inkcanvas wpf中显示或绘制文本可以通过以下步骤实现:
<InkCanvas x:Name="myInkCanvas" Background="White" />
TextBlock textBlock = new TextBlock();
textBlock.Text = "Hello, World!";
textBlock.FontSize = 20;
InkCanvas.SetLeft(textBlock, 100);
InkCanvas.SetTop(textBlock, 100);
myInkCanvas.Children.Add(textBlock);
InkPresenter inkPresenter = new InkPresenter();
inkPresenter.StrokesCollected += InkPresenter_StrokesCollected;
myInkCanvas.Children.Add(inkPresenter);
private void InkPresenter_StrokesCollected(InkPresenter sender, InkStrokesCollectedEventArgs args)
{
InkStrokeContainer strokeContainer = args.Strokes.GetInkStrokeContainer();
IReadOnlyList<InkStroke> strokes = strokeContainer.GetStrokes();
// 将笔迹转换为文本
RecognizerContainer recognizerContainer = new RecognizerContainer();
RecognizerContext recognizerContext = recognizerContainer.GetDefaultRecognizer();
RecognitionResult recognitionResult = await recognizerContext.RecognizeAsync(strokes);
// 获取识别的文本
string recognizedText = recognitionResult.Text;
// 在InkCanvas中显示识别的文本
TextBlock textBlock = new TextBlock();
textBlock.Text = recognizedText;
InkCanvas.SetLeft(textBlock, 100);
InkCanvas.SetTop(textBlock, 100);
myInkCanvas.Children.Add(textBlock);
}
这样,你就可以在InkCanvas中显示或绘制文本了。
