Параметры

left
Тип: System.Int32
The left bound of the rectangle with which to combine, in ink-space coordinates.

top
Тип: System.Int32
The top bound of the rectangle with which to combine, in ink-space coordinates.

right
Тип: System.Int32
The right bound of the rectangle with which to combine, in ink-space coordinates.

bottom
Тип: System.Int32
The bottom bound of the rectangle with which to combine, in ink-space coordinates.

Заметки

All parameters are in HIMETRIC units.

If either area is infinite, the new area is also infinite.

Примеры

The example uses Exclude, Intersect, and Union to modify the area of an existing AnalysisRegionBase named theFirstAnalysisRegionBase.

' Extend an AnalysisRegionBase using the Union method and
' an AnalysisRegionBase.
theFirstAnalysisRegionBase.Union(theSecondAnalysisRegionBase)

' Extend an AnalysisRegionBase using the Union method and a rectangle.
theFirstAnalysisRegionBase.Union(0, 500, 3000, 3500)

' Restrict an AnalysisRegionBase using the Intersect method and
' an AnalysisRegionBase.
theFirstAnalysisRegionBase.Intersect(theSecondAnalysisRegionBase)

' Restrict an AnalysisRegionBase using the Intersect method and a rectangle.
theFirstAnalysisRegionBase.Intersect(1000, 1000, 5000, 5000)

' Restrict an AnalysisRegionBase using the Exclude method and
' an AnalysisRegionBase.
theFirstAnalysisRegionBase.Exclude(theSecondAnalysisRegionBase)

' Modify an AnalysisRegionBase using the Exclude method and a rectangle.
theFirstAnalysisRegionBase.Exclude(1500, 1500, 2500, 2500)

// Extend an AnalysisRegionBase using the Union method and
// an AnalysisRegionBase.
theFirstAnalysisRegionBase.Union(theSecondAnalysisRegionBase);

// Extend an AnalysisRegionBase using the Union method and a rectangle.
theFirstAnalysisRegionBase.Union(0, 500, 3000, 3500);

// Restrict an AnalysisRegionBase using the Intersect method and
// an AnalysisRegionBase.
theFirstAnalysisRegionBase.Intersect(theSecondAnalysisRegionBase);

// Restrict an AnalysisRegionBase using the Intersect method and a rectangle.
theFirstAnalysisRegionBase.Intersect(1000, 1000, 5000, 5000);

// Restrict an AnalysisRegionBase using the Exclude method and
// an AnalysisRegionBase.
theFirstAnalysisRegionBase.Exclude(theSecondAnalysisRegionBase);

// Modify an AnalysisRegionBase using the Exclude method and a rectangle.
theFirstAnalysisRegionBase.Exclude(1500, 1500, 2500, 2500);
