Public Function New( _ 
   ByVal ratio As Integer, _ 
   ByVal dimension As Integer _ 
) 
public: 
ColoredPencilCommand(  
   int ratio, 
   int dimension 
) 

Parameters

ratio
Value that represents how much the image colors should be adjusted so they appear to be colored pencil colors. Valid values range from 0 to 100. A value of 0 means that the image will not have any change in pixel values whereas a value of 100 means that the maximum possible amount will be added to the pixel values.

dimension
Value that represents the size of the pencil coloring neighborhood. It is the length, in pixels, of one side of a square. Valid values range from 0 to 100. Increasing this value increases the thickness of the edges that are detected.

Example

Run the ColoredPencilCommand on an image and applies the Colored Pencil filter.
