Detailed Description

Concrete implementation of IOutlineInfo. Intended to be used as a glue class for calculating a path's bounding box using information from IPathGeometry and other interfaces that use IOutlineInfo.

Similar to PathBoundsOutlineInfo, but takes into account stroke parameters when calculating bounds, so that returned bounds reflect the bounds that would be marked if the path were stroked.

Constructor & Destructor Documentation

StrokeBoundsOutlineInfo::StrokeBoundsOutlineInfo	(	const PMReal &	strokeWeight,
		const PMReal &	miterLimit,
		int32	joinType,
		int32	lineCap,
		const PMMatrix &	xForm,
		IGraphicStyleDescriptor *	styleDescriptor
	)

Constructs a StrokeBoundsOutlineInfo with the specified stroke parameters and a matrix that will used to define the coordinate system for the input points and the scaling applied to the stroke weight.

Parameters

strokeWeight	IN The stroke's weight
miterLimit	IN The stroke's miter limit
joinType	IN The stroke's join type
lineCap	IN The stroke's line cap
xForm	IN The matrix defining the coordinate system for the input points
styleDescriptor	IN Style descriptor defining additional relevant stroke parameters (not currently used). Not AddRef'd

Member Function Documentation

virtual void StrokeBoundsOutlineInfo::BeginPath ( )

virtual

Begins a new path. Called before any of the other methods is called.

Implements IOutlineInfo.

virtual void StrokeBoundsOutlineInfo::closepath ( )

virtual

Closes the current subpath. If the first point in the subpath (defined by a prior call to moveto) does not correspond to the current point, this call will implicitly add a line segment from the current point to the first point in the subpath.

The current point is undefined after a call to closepath. The caller must call moveto to start a new subpath and establish the current point before calling either lineto, curveto, or closepath.

Implements IOutlineInfo.

virtual void StrokeBoundsOutlineInfo::curveto ( const PMReal &  x1, const PMReal &  y1, const PMReal &  x2, const PMReal &  y2, const PMReal &  x3, const PMReal &  y3  )

virtual

Adds a new bezier curve segment to the current subpath, using four control points. The current point in user space at the time the call is made is used as the starting point for the curve. (x1, y1) and (x2, y2) are used as control points defining the degree of curvature and magnitude of the curve, and (x3, y3) defines the end point. The current point is implicitly set to (x3, y3).

Parameters

x1	IN The x-component for the first control point of the new bezier segment
y1	IN The y-component for the first control point of the new bezier segment
x2	IN The x-component for the second control point of the new bezier segment
y2	IN The y-component for the second control point of the new bezier segment
x3	IN The x-component for the end point of the new bezier segment
y3	IN The y-component for the end point of the new bezier segment

Implements IOutlineInfo.

virtual void StrokeBoundsOutlineInfo::EndPath ( )

virtual

Ends a path begun by BeginPath.

Implements IOutlineInfo.

PMRect StrokeBoundsOutlineInfo::GetBoundingBox

(

)

Returns the computed bounds

Returns

the computed bounds

virtual void StrokeBoundsOutlineInfo::lineto ( const PMReal &  x, const PMReal &  y  )

virtual

Adds a line segment to the current subpath. The beginning of the segment is the current point in user space at the time the call is made. The end is (x, y). Implicitly sets the current point to (x, y).

Parameters

x	IN The x-component for the end point of the new line segment
y	IN The y-component for the end point of the new line segment

Implements IOutlineInfo.

virtual void StrokeBoundsOutlineInfo::moveto ( const PMReal &  x, const PMReal &  y  )

virtual

Starts a new subpath. The current point in user space is set to (x, y).

Parameters

x	IN The x-component of the new current point
y	IN The y-component of the new current point

Implements IOutlineInfo.
