C++

public static RasterRenderBuffer CreateFromWriteableBitmap( 
   int pixelWidth,
   int pixelHeight,
   IBuffer pixelBuffer
)

'Declaration
 
Public Shared Function CreateFromWriteableBitmap( _
   ByVal pixelWidth As Integer, _
   ByVal pixelHeight As Integer, _
   ByVal pixelBuffer As IBuffer _
) As RasterRenderBuffer

'Usage
 
Dim pixelWidth As Integer
Dim pixelHeight As Integer
Dim pixelBuffer As IBuffer
Dim value As RasterRenderBuffer
 
value = RasterRenderBuffer.CreateFromWriteableBitmap(pixelWidth, pixelHeight, pixelBuffer)

public static RasterRenderBuffer CreateFromWriteableBitmap( 
   int pixelWidth,
   int pixelHeight,
   IBuffer pixelBuffer
)

 function Leadtools.Converters.RasterRenderBuffer.CreateFromWriteableBitmap( 
   pixelWidth ,
   pixelHeight ,
   pixelBuffer 
)

public:
static RasterRenderBuffer^ CreateFromWriteableBitmap( 
   int pixelWidth,
   int pixelHeight,
   IBuffer^ pixelBuffer
)

Parameters

pixelWidth: The pixel width of the bitmap. Set this to WriteableBitmap.PixelWidth. Must be a value greater than 0.
pixelHeight: The pixel height of the bitmap. Set this to WriteableBitmap.PixelHeight. Must be a value greater than 0.
pixelBuffer: The pixels data. Set this to WriteableBitmap.PixelBuffer. Must not be null.

Return Value

The newly created RasterRenderBuffer object.

Remarks

This is a helper method that sets the values of the returned RasterRenderBuffer as follows:

Member	Value
Width	pixelWidth
Height	pixelHeight
BitsPerPixel	32. This is the only value supported in this version and cannot be changed.
Order	RasterByteOrder.Bgr since BGR color data is the format used by Windows Runtime WriteableBitmap.
Internal buffer data	This method will call SetDataBuffer with pixelBuffer.

Example

For an example, refer to RasterImageRenderer.
