IAnalysisRegion interface

Exposes methods and properties for a region that represents an area of a document.

Members

The IAnalysisRegion interface inherits from the IUnknown interface. IAnalysisRegion also has these types of members:

• Methods

Methods

The IAnalysisRegion interface has these methods.

Method	Description
Clone	Creates a copy of the IAnalysisRegion.
ExcludeRectangle	Restricts the area of the IAnalysisRegion to the portion of its area that does not intersect the specified rectangle.
ExcludeRegion	Restricts the area of the IAnalysisRegion to the portion of its area that does not intersect the specified IAnalysisRegion.
GetBounds	Retrieves the bounding rectangle of the IAnalysisRegion.
GetRegionScans	Retrieves an array of rectangles that defines the area of the IAnalysisRegion.
IntersectRectangle	Restricts the area of this IAnalysisRegion to the area created by its intersection with the specified rectangle.
IntersectRegion	Restricts the area of the IAnalysisRegion to the area created by its intersection with the specified IAnalysisRegion.
IntersectsWith	Determines whether the area of the IAnalysisRegion intersects with the specified rectangle.
IsEmpty	Retrieves a value indicating whether the IAnalysisRegion represents an empty region.
IsInfinite	Retrieves a value indicating whether the IAnalysisRegion represents an infinite region.
MakeEmpty	Reduces the IAnalysisRegion to represent an empty area.
MakeInfinite	Expands the IAnalysisRegion to represent an infinite area.
UnionRectangle	Expands the area of this IAnalysisRegion to the area created by its union with the specified rectangle.
UnionRegion	Expands the area of this IAnalysisRegion to the area created by its union with the specified IAnalysisRegion.

Remarks

This interface represents an area that is constructed from rectangular regions. The IInkAnalyzer returns or interprets an area's coordinates within the coordinate space in which it receives stroke data.

To get the current bounds of the IAnalysisRegion, use IAnalysisRegion::GetBounds Method or IAnalysisRegion::GetRegionScans Method.

To modify the area of an existing IAnalysisRegion, use the following methods.

• IAnalysisRegion::ExcludeRectangle
• IAnalysisRegion::ExcludeRegion Method
• IAnalysisRegion::IntersectRectangle Method
• IAnalysisRegion::IntersectRegion Method
• IAnalysisRegion::MakeEmpty Method
• IAnalysisRegion::MakeInfinite Method
• IAnalysisRegion::UnionRectangle Method
• IAnalysisRegion::UnionRegion Method

This interface is equivalent to the System.Windows.Ink.AnalysisCore.AnalysisRegionBase class in the .NET Framework.
