Initializes a new GlowCommand class object with explicit parameters.
Syntax
Visual Basic (Usage) | Copy Code |
---|
Dim dimension As Integer
Dim brightness As Integer
Dim threshold As Integer
Dim instance As New GlowCommand(dimension, brightness, threshold) |
Parameters
- dimension
- Size of the neighborhood used to determine the width of the glow. This parameter only accepts positive values.
- brightness
- Brightness factor used to create the "glow". This can be any number that is 0 or greater. If it is 0 the image will be black.
- threshold
- Threshold value used to determine which pixels are edge pixels. If the difference determined for a pixel is greater than this value, the pixel is an edge pixel. Valid values range from 0 through 255. Use this parameter to control the number of edge pixels found.
Example
Run the Leadtools.ImageProcessing.SpecialEffects.GlowCommand on an image.
