Blur effect parameter structure
Global Const $tagGDIP_EFFECTPARAMS_Blur = "float Radius; bool ExpandEdge"
| Radius | Real number that specifies the sharpening radius (the radius of the convolution kernel) in pixels. The radius must be in the range 0.0 through 255.0 |
| ExpandEdge | Boolean value that specifies whether the bitmap expands by an amount equal to the blur radius. If TRUE, the bitmap expands by an amount equal to the radius so that it can have soft edges. If FALSE, the bitmap remains the same size and the soft edges are clipped |
