A path consists of one or more<br /> figures. You can use a [[Class IGDIPlus.TGPGraphicsPathIterator|TGPGraphicsPathIterator]] to isolate one<br /> or more of those figures. A path can also have markers that<br /> divide the path into sections. You can use a<br /> [[Class IGDIPlus.TGPGraphicsPathIterator|TGPGraphicsPathIterator]] object to isolate one or more of<br /> those sections.<br /> <br /> == Methods ==<br /> *[[Method function IGDIPlus.IGPGraphicsPathIterator.NextSubpath(Integer;Integer;bool) : Integer|function NextSubpath(startIndex : Integer; endIndex : Integer; isClosed : bool) : Integer]] - Returns the starting index and the ending index of the next subpath (figure) in the iterator's associated path. <br /> *[[Method function IGDIPlus.IGPGraphicsPathIterator.NextSubpath(IGPGraphicsPath;Boolean) : Integer|function NextSubpath(path : IGPGraphicsPath; isClosed : Boolean) : Integer]] - Returns the next figure (subpath) from the iterator's associated path. <br /> *[[Method function IGDIPlus.IGPGraphicsPathIterator.NextPathType(TGPPathPointType;Integer;Integer) : Integer|function NextPathType(pathType : TGPPathPointType; startIndex : Integer; endIndex : Integer) : Integer]] - Returns the starting index and the ending index of the next group of data points that all have the same type. <br /> *[[Method function IGDIPlus.IGPGraphicsPathIterator.NextMarker(Integer;Integer) : Integer|function NextMarker(startIndex : Integer; endIndex : Integer) : Integer]] - Returns the starting index and the ending index of the next marker-delimited section in the iterator's associated path. <br /> *[[Method function IGDIPlus.IGPGraphicsPathIterator.NextMarker(IGPGraphicsPath) : Integer|function NextMarker(path : IGPGraphicsPath) : Integer]] - Returns the next marker-delimited section of the iterator's associated path. <br /> *[[Method function IGDIPlus.IGPGraphicsPathIterator.GetCount() : Integer|function GetCount() : Integer]] - Returns the number of data points in the path. <br /> *[[Method function IGDIPlus.IGPGraphicsPathIterator.GetSubpathCount() : Integer|function GetSubpathCount() : Integer]] - Returns the number of subpaths (also called figures) in the path. <br /> *[[Method function IGDIPlus.IGPGraphicsPathIterator.HasCurve() : Boolean|function HasCurve() : Boolean]] - Determines whether the path has any curves. <br /> *[[Method function IGDIPlus.IGPGraphicsPathIterator.Rewind() : TGPGraphicsPathIterator|function Rewind() : TGPGraphicsPathIterator]] - Rewinds the iterator to the beginning of its associated path. <br /> *[[Method function IGDIPlus.IGPGraphicsPathIterator.Enumerate(TGPPointFArray;TGPByteArray) : Integer|function Enumerate(points : TGPPointFArray; types : TGPByteArray) : Integer]] - Returns the path's data points as a [[Structure IGDIPlus.TGPPointF|TGPPointF]] array and the path's point types as a BYTE array. <br /> *[[Method function IGDIPlus.IGPGraphicsPathIterator.CopyData(PGPPointF;PBYTE;Integer;Integer) : Integer|function CopyData(points : PGPPointF; types : PBYTE; startIndex : Integer; endIndex : Integer) : Integer]] - Copies a subset of the path's data points to a PointF array and copies a subset of the path's point types to a BYTE array. <br /> <br /> [[Category:Interfaces]]</div>
