Initializes a new
EdgeDetectEffectCommand class object with explicit parameters.
Supported in Silverlight, Windows Phone 7
Syntax
Parameters
- level
- Level value used to determine the brightness of the edges. Standard value is 50. Range between 1 and 100. Big values will produce bright edges.
- threshold
- Threshold value used to determine which pixels are going to be filtered. If the difference determined for a pixel is less than this value, the pixel is set to 0. If the difference is greater, the filter will be applied to the pixel. This parameter only accepts positive values.
- type
- Flag that indicates the type of edge to generate.
Example
Run the EdgeDetectEffectCommand on an image.
