MACROMEDIA FLASH 8-ACTIONSCRIPT 2.0 LANGUAGE - Convolutionfilter Constructor

ConvolutionFilter (flash.filters.ConvolutionFilter) 465
ConvolutionFilter constructor
public ConvolutionFilter(matrixX:Number, matrixY:Number, matrix:Array,
[divisor:Number], [bias:Number], [preserveAlpha:Boolean],
[clamp:Boolean], [color:Number], [alpha:Number])
Initializes a ConvolutionFilter instance with the specified parameters.
Availability: ActionScript 1.0; Flash Player 8
Parameters
matrixX:Number - The x dimension of the matrix (the number of columns in the matrix).
The default value is 0.
matrixY:Number - The y dimension of the matrix (the number of rows in the matrix). The
default value is 0.
matrix:Array - The array of values used for matrix transformation; returns a copy. The
number of items in the array must equal
matrixX*matrixY.
divisor:Number [optional] - The divisor used during matrix transformation. The default
value is 1. A divisor that is the sum of all the matrix values evens out the overall color intensity
of the result. A value of 0 is ignored and the default is used instead.
bias:Number [optional] - The bias to add to the result of the matrix transformation. The
default value is 0.
preserveAlpha:Boolean [optional] - A value of false indicates that the convolution applies
to all channels, including the alpha channel. A value of
true indicates that the convolution
applies only to the color channels. The default value is
true.
clamp:Boolean [optional] - For pixels that are off the source image, a value of true indicates
that the input image is extended along each of its borders as necessary by duplicating the color
values at the given edge of the input image. A value of
false indicates that another color
should be used, as specified in the
color and alpha properties. The default is true.
color:Number [optional] - The hexadecimal color to substitute for pixels that are off the
source image.
alpha:Number [optional] - The alpha of the substitute color.
Example
The following code creates a 3 x 3 convolution filter with a divisor of 9. The filter would
make an image appear blurred:
var myArray:Array = [1, 1, 1, 1, 1, 1, 1, 1, 1];
var myFilter:ConvolutionFilter = new flash.filters.ConvolutionFilter (3,
3, myArray, 9);
