ImGearROIMask Constructor(ImGearPage,ImGearPixel,Boolean)

In This Topic

Initializes a new instance of the ImGearROIMask class, corresponding to an area in the specified page that is filled with the specified color.

Syntax

Visual Basic
C#
Managed Extensions for C++
C++/CLI

'Declaration
 
Public Function New( _
   ByVal page As ImGearPage, _
   ByVal maskColor As ImGearPixel, _
   ByVal invertSelection As Boolean _
)

'Usage
 
Dim page As ImGearPage
Dim maskColor As ImGearPixel
Dim invertSelection As Boolean
 
Dim instance As New ImGearROIMask(page, maskColor, invertSelection)

public ImGearROIMask( 
   ImGearPage page,
   ImGearPixel maskColor,
   bool invertSelection
)

public: ImGearROIMask( 
   ImGearPage* page,
   ImGearPixel* maskColor,
   bool invertSelection
)

public:
ImGearROIMask( 
   ImGearPage^ page,
   ImGearPixel^ maskColor,
   bool invertSelection
)

Parameters

page: The page used to construct the ROI mask. Binary (1-bit) pages are not supported.
maskColor: Mask color.
invertSelection: Set to true to build mask according to area not filled with MaskColor.

Remarks

Creates an instance of ImGearROIMask object corresponding to area in the page that is filled with maskColor. If invertSelection is true, the mask is created for the area that is not filled with maskColor.

The ImGearPixel passed as maskColor should correspond to page's number of channels and bit depth.

Example

C#
Visual Basic

// Set ROI to area that is not filled with Pixel Padding Value
ImGearPixel ppv = new ImGearPixel(1, 16);
ppv[0] = 1024;
ImGearRasterPage rasterPage = (ImGearRasterPage)page;
rasterPage.ROI = new ImGearROIMask(page, ppv, true);

' Set ROI to area that is not filled with Pixel Padding Value
Dim ppv As ImGearPixel = New ImGearPixel(1, 16)
ppv(0) = 1024
Dim rasterPage As ImGearRasterPage = igPage
rasterPage.ROI = New ImGearROIMask(igPage, ppv, True)
