GetGdiPlusRegionData Method

Gets the GDI+ data that describes the image region.

Syntax

public static RegionData GetGdiPlusRegionData( 
   RasterImage image,
   RasterRegionXForm xform
)

'Declaration

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

'Usage

Dim image As RasterImage
Dim xform As RasterRegionXForm
Dim value As RegionData
 
value = RasterRegionConverter.GetGdiPlusRegionData(image, xform)

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

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 Visual Basic) for this parameter, the scalar fields default to 1, the offsets default to 0, and the view perspective defaults to the image view perspective.

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.
