region1: First ROI to merge.

imageRect1: First image rectangle.

region2: Second ROI to merge.

imageRect2: Second image rectangle.

offsetX: Horisontal offset of the second ROI and image rectangle.

offsetY: Vertical offset of the second ROI and image rectangle.

Creates a new ImGearROI instance that is calculated as an intersection of specified ROI and image rectangles.

) As ImGearROI

'Usage
 
Dim region1 As ImGearROI
Dim imageRect1 As ImGearRectangle
Dim region2 As ImGearROI
Dim imageRect2 As ImGearRectangle
Dim offsetX As Integer
Dim offsetY As Integer
Dim value As ImGearROI
 
value = ImGearROI.Intersect(region1, imageRect1, region2, imageRect2, offsetX, offsetY)

public static ImGearROI Intersect( 
   ImGearROI region1,
   ImGearRectangle imageRect1,
   ImGearROI region2,
   ImGearRectangle imageRect2,
   int offsetX,
   int offsetY
)

public: static ImGearROI* Intersect( 
   ImGearROI* region1,
   ImGearRectangle imageRect1,
   ImGearROI* region2,
   ImGearRectangle imageRect2,
   int offsetX,
   int offsetY
)

public:
static ImGearROI^ Intersect( 
   ImGearROI^ region1,
   ImGearRectangle imageRect1,
   ImGearROI^ region2,
   ImGearRectangle imageRect2,
   int offsetX,
   int offsetY
)

Parameters

region1: First ROI to merge.
imageRect1: First image rectangle.
region2: Second ROI to merge.
imageRect2: Second image rectangle.
offsetX: Horisontal offset of the second ROI and image rectangle.
offsetY: Vertical offset of the second ROI and image rectangle.

Return Value

ImGearROI class object.

Remarks

This method calculate an intersection of regions of interest from two images. Images can have different dimensions, and second image may be positioned at a specified offset relative to the first one. Coordinates of result ROI are relative to the left top corner of the first image.
