GetGdiPlusRegionData Method

Summary

Gets the GDI+ data that describes the image region.

Syntax

C++

public static RegionData GetGdiPlusRegionData( 
   RasterImage image, 
   RasterRegionXForm xform 
)

Public Shared Function GetGdiPlusRegionData( _ 
   ByVal image As RasterImage, _ 
   ByVal xform As RasterRegionXForm _ 
) As RegionData

public: 
static RegionData^ GetGdiPlusRegionData(  
   RasterImage^ image, 
   RasterRegionXForm^ xform 
)

Parameters

image
The source image.

xform
Leadtools.RasterRegionXForm object that LEADTOOLS uses to translate between display coordinates and image coordinates. If you specify null (Nothing in VB) for this parameter, the scalar fields default to 1, the offsets default to 0, and the view perspective defaults to the image view perspective.

Return Value

A System.Drawing.Drawing2D.RegionData object that contains the information that describes the region in this Leadtools.RasterImage object.

Remarks

Used with AddGdiPlusDataToRegion to load or save an image region.

The data returned by this method is the equivalent of the data returned using the GDI+ System.Drawing.Region.GetRegionData method.

To get the region data as Windows API HRGN data, use GetGdiRegionData and AddGdiDataToRegion.

To get the region data as platform independent byte array, use RasterRegion.GetData and RasterRegion.SetData.

For more information refer to RasterImage and GDI/GDI+.

Example

For an example, refer to AddGdiPlusDataToRegion.
