ImageGear21.Processing.Advanced Assembly > ImageGear.Processing Namespace > ImGearEffects Class > EdgeMap Method : EdgeMap(ImGearRasterPage,ImGearEdgeMapMethods,ImGearChannelRange) Method

page: An ImageGear.Core.ImGearRasterPage class object to detect edge map for.

method: Type of edge map operation to perform.

channels: Channel range to apply the operation.

Performs the edge map operation specified by the method argument. Processes a specified range of channels.

'Declaration
 
Public Overloads Shared Sub EdgeMap( _
   ByVal page As ImGearRasterPage, _
   ByVal method As ImGearEdgeMapMethods, _
   ByVal channels As ImGearChannelRange _
)

'Usage
 
Dim page As ImGearRasterPage
Dim method As ImGearEdgeMapMethods
Dim channels As ImGearChannelRange
 
ImGearEffects.EdgeMap(page, method, channels)

public static void EdgeMap( 
   ImGearRasterPage page,
   ImGearEdgeMapMethods method,
   ImGearChannelRange channels
)

public: static void EdgeMap( 
   ImGearRasterPage* page,
   ImGearEdgeMapMethods method,
   ImGearChannelRange channels
)

public:
static void EdgeMap( 
   ImGearRasterPage^ page,
   ImGearEdgeMapMethods method,
   ImGearChannelRange channels
)

Parameters

page: An ImageGear.Core.ImGearRasterPage class object to detect edge map for.
method: Type of edge map operation to perform.
channels: Channel range to apply the operation.

Remarks

An edge map is an image that shows where there are changes in contrast in the original image. Where there are no changes, the resulting image is black. The stronger the contrast change, the brighter the resultant image. The different types of edge maps are slight variations of the algorithms used, and produce slightly different results.

This method takes into account the ROI settings of page object, that are accessible via the ImageGear.Core.ImGearRasterPage.ROI property. By default ROI is set to the entire image.
