Variable Summary
| name | type | Default Value | description |
|---|---|---|---|
| input | Effect | null |
The input for this |
| width | Number | 5.0 |
The horizontal dimension of the blur effect. The color information for a given pixel will be spread across a Box of the indicated width centered over the pixel. Values less than or equal to 1 will not spread the color data beyond the pixel where it originated from and so will have no effect.
Min: 0.0
Max: 255.0
Default: 5.0
Identity: <1.0
|
| height | Number | 5.0 |
The vertical dimension of the blur effect. The color information for a given pixel will be spread across a Box of the indicated height centered over the pixel. Values less than or equal to 1 will not spread the color data beyond the pixel where it originated from and so will have no effect.
Min: 0.0
Max: 255.0
Default: 5.0
Identity: <1.0
|
| iterations | Integer | 1 |
The number of times to iterate the blur effect to improve its "quality" or "smoothness". Iterating the effect 3 times approximates the quality of a Gaussian Blur to within 3%.
Min: 0
Max: 3
Default: 1
Identity: 0
