GetGdiRegionData Method

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 byte[] GetGdiRegionData( 
   RasterImage image,
   RasterRegionXForm xform
)

 function Leadtools.Drawing.RasterRegionConverter.GetGdiRegionData( 
   image ,
   xform 
)

public:
static array<byte>^ GetGdiRegionData( 
   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 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.

Return Value

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 GDI+ System.Drawing.Drawing2D.RegionData object, use GetGdiPlusRegionData and AddGdiPlusDataToRegion.

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+.

Target Platforms: Windows 7, Windows Vista SP1 or later, Windows XP SP3, Windows Server 2008 (Server Core not supported), Windows Server 2008 R2 (Server Core supported with SP1 or later), Windows Server 2003 SP2
