Leadtools Namespace > RasterImage Class : AddDataToRegion Method




xform
RasterRegionXForm object that LEADTOOLS uses to translate between display coordinates and image coordinates. If you specify null (Nothing in Visual Basic) in this parameter, the scalar fields default to 1, the offsets default to 0, and the view perspective defaults to the image view perspective.
data
Array of bytes that describe the region data.
dataOffset
Zero-based index into data.
combineMode
The action to take regarding the existing image region, if one is defined.
Creates or updates the image region using the specified region data.

Syntax

Public Sub AddDataToRegion( _
   ByVal xform As RasterRegionXForm, _
   ByVal data() As Byte, _
   ByVal dataOffset As Integer, _
   ByVal combineMode As RasterRegionCombineMode _
) 
Visual Basic (Usage)Copy Code
Dim instance As RasterImage
Dim xform As RasterRegionXForm
Dim data() As Byte
Dim dataOffset As Integer

void AddDataToRegion( 
   RasterRegionXForm^ xform,
   array<byte>^ data,
   int dataOffset,

) 

Parameters

xform
RasterRegionXForm object that LEADTOOLS uses to translate between display coordinates and image coordinates. If you specify null (Nothing in Visual Basic) in this parameter, the scalar fields default to 1, the offsets default to 0, and the view perspective defaults to the image view perspective.
data
Array of bytes that describe the region data.
dataOffset
Zero-based index into data.
combineMode
The action to take regarding the existing image region, if one is defined.

Example

Refer to AddDataToRegion.
This example will show how to use GetRegionData and AddDataToRegion to save/load an image region

Remarks

To update an existing region, you specify how the new region is to be combined with the existing one using the combineMode parameter. For more information, refer to RasterRegionCombineMode.

For more information, refer to Creating a Region.

For more information, refer to Saving A Region.

For more information, refer to Working with the Existing Region.

Requirements

Target Platforms: Microsoft .NET Framework 2.0, Windows 98, Windows NT 4.0, Windows Millennium Edition, Windows 2000, Windows XP Home Edition, Windows XP Professional, Windows Server 2003 family
