Initializes a new ContourFilterCommand class object with explicit parameters.
Syntax
Parameters
- threshold
- Threshold of the gradient magnitude. Values below this will be considered as background, and will be set to 0. Values can be from 1 to 254. A lower threshold provides a better quality image. Default is 15.
- deltaDirection
- Maximum angle for the thinning algorithm. Values can be from 1 to 64. Default is 35.
- maximumError
- Maximum error for approximation algorithm. Values can be from 0 to 255. Default is 5. This parameter is only valid if the type parameter is set to ApproxColor.
- type
- Flag that controls the resulting image. This value tells the command what process to complete before returning.
Example
Run the ContourFilterCommand on an image with LinkColor Option.
