Esempi

In questo esempio vengono creati due oggetti AnalysisRegion. Vengono utilizzati i metodi Intersect, Union e Exclude per modificare le aree degli oggetti.

' Create an infinite AnalysisRegion.
Dim theFirstAnalysisRegion As New Microsoft.Ink.AnalysisRegion()

' Create a finite AnalysisRegion.
Dim theSecondAnalysisRegion As New Microsoft.Ink.AnalysisRegion( _
    New System.Drawing.Rectangle(205, 205, 2054, 1027))

' Extend an AnalysisRegion using the Union method and an AnalysisRegion.
theFirstAnalysisRegion.Union(theSecondAnalysisRegion)

' Extend an AnalysisRegion using the Union method and a rectangle.
theFirstAnalysisRegion.Union(New Rectangle(0, 2054, 2054, 1027))

' Restrict an AnalysisRegion using the Intersect method and an AnalysisRegion.
theFirstAnalysisRegion.Intersect(theSecondAnalysisRegion)

' Restrict an AnalysisRegion using the Intersect method and a rectangle.
theFirstAnalysisRegion.Intersect(New Rectangle(750, 1000, 2500, 1500))

' Modify an AnalysisRegion using the Exclude method and an AnalysisRegion.
theFirstAnalysisRegion.Exclude(theSecondAnalysisRegion)

' Modify an AnalysisRegion using the Exclude method and a rectangle.
theFirstAnalysisRegion.Exclude(New Rectangle(750, 1000, 500, 500))

            // Create an infinite AnalysisRegion.
            Microsoft.Ink.AnalysisRegion theFirstAnalysisRegion =
                new Microsoft.Ink.AnalysisRegion();

            // Create a finite AnalysisRegion.
            Microsoft.Ink.AnalysisRegion theSecondAnalysisRegion =
                new Microsoft.Ink.AnalysisRegion(
                    new System.Drawing.Rectangle(205, 205, 2054, 1027));

            // Extend an AnalysisRegion using the Union method and an AnalysisRegion.
            theFirstAnalysisRegion.Union(theSecondAnalysisRegion);

            // Extend an AnalysisRegion using the Union method and a rectangle.
            theFirstAnalysisRegion.Union(new Rectangle(0, 2054, 2054, 1027));

            // Restrict an AnalysisRegion using the Intersect method and an AnalysisRegion.
            theFirstAnalysisRegion.Intersect(theSecondAnalysisRegion);

            // Restrict an AnalysisRegion using the Intersect method and a rectangle.
            theFirstAnalysisRegion.Intersect(new Rectangle(750, 1000, 2500, 1500));

            // Modify an AnalysisRegion using the Exclude method and an AnalysisRegion.
            theFirstAnalysisRegion.Exclude(theSecondAnalysisRegion);

            // Modify an AnalysisRegion using the Exclude method and a rectangle.
            theFirstAnalysisRegion.Exclude(new Rectangle(750, 1000, 500, 500));
