AddBeziersToRegion(RasterRegionXForm,RasterCollection<LeadPoint>,LeadFillMode,RasterRegionCombineMode) Method
Summary
Creates or updates the image region by adding a Bézier region.
Syntax
public void AddBeziersToRegion(Leadtools.RasterRegionXForm xform,Leadtools.RasterCollection<LeadPoint> points,Leadtools.LeadFillMode fillMode,Leadtools.RasterRegionCombineMode combineMode)
Public Overloads Sub AddBeziersToRegion( _ByVal xform As Leadtools.RasterRegionXForm, _ByVal points As Leadtools.RasterCollection(Of LeadPoint), _ByVal fillMode As Leadtools.LeadFillMode, _ByVal combineMode As Leadtools.RasterRegionCombineMode _)
public void addBeziersToRegion(RasterRegionXForm xform,RasterCollection<LeadPoint> points,Path.FillType fillMode,RasterRegionCombineMode combineMode)
public:void AddBeziersToRegion(Leadtools.RasterRegionXForm^ xform,Leadtools.RasterCollection<LeadPoint>^ points,Leadtools.LeadFillMode fillMode,Leadtools.RasterRegionCombineMode combineMode)
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 |
|---|---|
| LeadFillMode.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. |
combineMode
The action to take regarding the existing image region, if one is defined.
Remarks
To update an existing region, you specify how the new region is to be combined with the existing one using the combineMode parameter. For more information, refer to RasterRegionCombineMode.
