DetectArea Method

This method detects an area of pixels using a specified pixel checker. The area being detected is saved as the ROI of the page.

Syntax

public static void DetectArea( 
   ImGearRasterPage page,
   ImGearPoint point,
   IImGearPixelChecker checker
)

public: static void DetectArea( 
   ImGearRasterPage* page,
   ImGearPoint point,
   IImGearPixelChecker* checker
)

public:
static void DetectArea( 
   ImGearRasterPage^ page,
   ImGearPoint point,
   IImGearPixelChecker^ checker
)

'Declaration
 
Public Shared Sub DetectArea( _
   ByVal page As ImGearRasterPage, _
   ByVal point As ImGearPoint, _
   ByVal checker As IImGearPixelChecker _
)

'Usage
 
Dim page As ImGearRasterPage
Dim point As ImGearPoint
Dim checker As IImGearPixelChecker
 
ImGearEffects.DetectArea(page, point, checker)

Parameters

page: Page class object.
point: A point inside the area to be searched.
checker: Implementation of IImGearPixelChecker interface with the implemented method CheckPixel. See IImGearPixelChecker interface for more details.
