GetGdiRegionData Method

Gets the GDI data that describes the image region.

Syntax

public static byte[] GetGdiRegionData( 
   RasterImage image,
   RasterRegionXForm xform
)

'Declaration

Public Shared Function GetGdiRegionData( _
   ByVal image As RasterImage, _
   ByVal xform As RasterRegionXForm _
) As Byte()

'Usage

Dim image As RasterImage
Dim xform As RasterRegionXForm
Dim value() As Byte
 
value = RasterRegionConverter.GetGdiRegionData(image, xform)

public:
static array<byte>^ GetGdiRegionData( 
   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.

An array of System.Byte that contains the information that describes the region in this Leadtools.RasterImage object.

Remarks

Used with AddGdiDataToRegion to load or save an image region.

The data returned by this method is the equivalent of the data returned using the Windows GetRegionData API.

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 AddGdiDataToRegion.
