Заметки

When the InkAnalyzer adds a ContextNode from the saved results, it assigns a new globally unique identifier (GUID) to the ContextNode object's Id() property.

This method appends the saved analysis results to existing results. To ensure that the combined results are ordered correctly, add the area containing the loaded context nodes to the ink analyzer's DirtyRegion and then reanalyze the ink.

If a saved analysis hint conflicts with an existing analysis hint, the InkAnalyzer does not load that saved hint although it loads the rest of the saved results. However, if saved stroke data is within the area of an unloaded saved analysis hint, the InkAnalyzer adds the bounding box of the stroke to the analyzer's DirtyRegion. If saved stroke data is within an existing analysis hint's area, the analyzer also adds the bounding box of the stroke to the analyzer's DirtyRegion. For more information about analysis hints, see AnalysisHintNode.

The InkAnalyzer raises the ContextNodeCreated, ContextNodeLinkAdding, and ContextNodePropertiesUpdated events as it loads saved results.

Примеры

This example loads saved analysis results from a MemoryStream named theSavedResults into the InkAnalyzer, named theInkAnalyzer.

' Load previously saved analysis results and associated ink data.
successful = Me.theInkAnalyzer.Load(theSavedResults)

// Load previously saved analysis results and associated ink data.
successful = this.theInkAnalyzer.Load(theSavedResults);
