ImageGear .NET
EdgeMap(ImGearRasterPage,ImGearEdgeMapMethods,ImGearChannelRange) Method




An ImageGear.Core.ImGearRasterPage class object to detect edge map for.
Type of edge map operation to perform.
Channel range to apply the operation.
Performs the edge map operation specified by the method argument. Processes a specified range of channels.
Syntax
'Declaration

'Usage
 
Dim page As ImGearRasterPage

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.
