Detailed Description

Interface for outsetting (i.e., negative inset) a path

Member Enumeration Documentation

anonymous enum

default IID for this interface

enum IOffsetPath::OffsetStyle

Offset strategy

Enumerator
kOffsetArea	old functionality: closes path and offsets hull
kOffsetPath	offsets stroke, without closing path

Member Function Documentation

virtual ErrorCode IOffsetPath::OffsetPath ( IPathGeometry const *  pathData, IOutlineInfo *  offsetPath, PMReal const &  amount, OffsetStyle  style = kOffsetArea, int32  joinType = kPMRoundJoin, int32  lineCap = kPMButtCap, PMReal const &  miterLimit = 1.0, bool16  unionPaths = kTrue  ) const

pure virtual

Offsets the path by nOffset amount. Will union the paths if bUnionPaths is true can specify join type, line cap, and miter limit directly.

Parameters

pathData	- IN: source path
offsetPath	- OUT: destination path
amount	- IN: non-zero amount to offset
style	- IN: offset style
joinType	- IN: join type
lineCap	- IN: linecap
miterLimit	- IN: miter limit
unionPaths	- IN: Should paths be unioned

Returns

ErrorCode. kSuccess indicates no error.
