FromPolygon Method
Summary
Creates a polygonal raster region.
Syntax
public static Leadtools.RasterRegion FromPolygon(Leadtools.RasterRegionXForm xform,IList<LeadPoint> points,Leadtools.LeadFillMode fillMode)
Public Shared Function FromPolygon( _ByVal xform As Leadtools.RasterRegionXForm, _ByVal points As IList(Of LeadPoint), _ByVal fillMode As Leadtools.LeadFillMode _) As Leadtools.RasterRegion
public:static Leadtools.RasterRegion^ FromPolygon(Leadtools.RasterRegionXForm^ xform,IList<LeadPoint>^ points,Leadtools.LeadFillMode fillMode)
Parameters
xform
RasterRegionXForm object that LEADTOOLS uses to translate between display coordinates and image coordinates. If you specify null in this parameter, the scalar fields default to 1, the offsets default to 0, and the view perspective defaults to the image view perspective.
points
A collection of LeadPoint objects. The points in the collection must be in the order in which the vertices of the polygon are connected. To create the line that closes the polygon, the last point in the collection is connected to the first point of the collection.
fillMode
Indicates how to handle complex crossing lines.
| Value | Meaning |
|---|---|
| LeadPoint.Winding | All pixels that are inside the resulting exterior lines are in the region. |
| LeadFillMode.Alternate | The region includes the area between odd-numbered and even-numbered polygon sides on each scan line. |
