Syntax

WinRT C#

C++

public static Leadtools.Converters.RasterRenderBuffer CreateFromHtmlImageData(  
   int imageDataWidth, 
   int imageDataHeight, 
   byte[] imageData 
)

Public Shared Function CreateFromHtmlImageData( _ 
   ByVal imageDataWidth As Integer, _ 
   ByVal imageDataHeight As Integer, _ 
   ByVal imageData() As Byte _ 
) As Leadtools.Converters.RasterRenderBuffer

public static Leadtools.Converters.RasterRenderBuffer CreateFromHtmlImageData(  
   int imageDataWidth, 
   int imageDataHeight, 
   byte[] imageData 
)

function Leadtools.Converters.RasterRenderBuffer.CreateFromHtmlImageData(  
   imageDataWidth , 
   imageDataHeight , 
   imageData  
)

public: 
static Leadtools.Converters.RasterRenderBuffer^ CreateFromHtmlImageData(  
   int imageDataWidth, 
   int imageDataHeight, 
   array<byte>^ imageData 
)

Parameters

imageDataWidth
The pixel width of the image data. Set this to ImageData.width. Must be a value greater than 0.

imageDataHeight
The pixel height of the image data. Set this to ImageData.height. Must be a value greater than 0.

imageData
The pixels data. Set this to ImageData.data. 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	imageDataWidth
Height	imageDataHeight
BitsPerPixel	32. This is the only value supported in this version and cannot be changed.
Order	RasterByteOrder.Rgb since RGB color data is the format used by HTML Canvas ImageData.
Internal buffer data	This method will call SetDataArray with imageData.

Example

For an example, refer to RasterImageRenderer.
