Detailed Description

IGeometry is designed to be a "geometry independent" way of defining an object, meaning that nothing in the interface makes any assumption as to the item being rectangular, linear, etc.

PageItems are defined by one or more points. It is up to the implementer to decide how to interpret these point in order to get a BoundingBox, etc. As a convenience there are two sets of methods, one for bounding box with stroke and one for bounding box without stroke. For certain pageitems, such as images, the path bounds and stroke bounds will be the same.

Note: IGeometry does NOT draw. IShape is used for drawing and is implemented in terms of IGeometry.

IGeometry is a required interface of page items.

virtual PMRect IGeometry::GetPathBoundingBox ( const PMMatrix & theMatrix ) const

pure virtual

Get the bounding box that exclude stroke but with no transformations done.

Parameters

theMatrix [In] parameter used to transform the BBox before returning. For example, if you want a PasteBoardBBox, pass in an InnerToPasteboard Matrix.

Returns: PMRect the result bounding box.

Implemented in CGeometry.

virtual PMRect IGeometry::GetPathBoundingBox ( ) const

pure virtual

Get the bounding box that exclude stroke. Bounding box returned is in inner coordinates.

Returns: PMRect the result bounding box.

Implemented in CGeometry.

virtual PMReal IGeometry::GetPathProportion ( ) const

pure virtual

Get the proportion(width/height) excluding stroke. This is a helper method for constraining.

Returns: PMReal by default this is the width of the bounding box divided by its height.

Implemented in CGeometry.

virtual PMRect IGeometry::GetStrokeBoundingBox ( const PMMatrix & theMatrix ) const

pure virtual

Get the bounding box that include stroke.

Parameters

theMatrix [In] parameter used to transform the BBox before returning. For example, if you want a PasteBoardBBox, pass in an InnerToPasteboard Matrix.

Returns: PMRect the result bounding box.

Implemented in CGeometry.

virtual PMRect IGeometry::GetStrokeBoundingBox ( ) const

pure virtual

Get the bounding box that include stroke but with no transformations done. Bounding box returned is in inner coordinates.

Returns: PMRect the result bounding box.

Implemented in CGeometry.

virtual PMReal IGeometry::GetStrokeProportion ( ) const

pure virtual

Get the proportion(width/height) including stroke. This is a helper method for constraining.

Returns: PMReal by default this is the width of the bounding box divided by its height.

Implemented in CGeometry.

virtual ErrorCode IGeometry::SetPathBoundingBox ( const PMRect & newBBox )

pure virtual

Set the bounding box without stroke in inner coordinates.

Parameters

newBBox	[In] parameter used to set the new bounding box.
whichAction	[In] parameter used to specify the action for children when doing this operation.

Returns: ErrorCode indicates the result of operation.

Implemented in CGeometry.

virtual ErrorCode IGeometry::SetPathBoundingBox	(	const PMMatrix &	theMatrix,
		const PMRect &	newBBox
	)

pure virtual

Set the bounding box without stroke.

Parameters

theMatrix	[In] parameter that may change the transform of the item depending on the implementation of IGeometry
newBBox	[In] parameter used to set the new bounding box.
whichAction	[In] parameter used to specify the action for children when doing this operation.

Returns: ErrorCode indicates the result of operation.

Implemented in CGeometry.

virtual ErrorCode IGeometry::SetStrokeBoundingBox ( const PMRect & newBBox )

pure virtual

Set the bounding box with stroke in inner coordinates.

Parameters

Returns: ErrorCode indicates the result of operation.

Implemented in CGeometry.

virtual ErrorCode IGeometry::SetStrokeBoundingBox	(	const PMMatrix &	theMatrix,
		const PMRect &	newBBox
	)

pure virtual

Set the bounding box with stroke.

Parameters

theMatrix	[In] parameter that may change the transform of the item depending on the implementation of IGeometry
newBBox	[In] parameter used to set the new bounding box.
whichAction	[In] parameter used to specify the action for children when doing this operation.

Returns: ErrorCode indicates the result of operation.

Implemented in CGeometry.
