ShaderFilter  - AS3 Flex

套件	spark.filters
類別	public dynamic class ShaderFilter
繼承	ShaderFilter Proxy
實作	IBitmapFilter, IEventDispatcher

The ShaderFilter class must be initialized with either an instance of a Shader object or Class representative of a Shader (such as from an Embed). The ShaderFilter class then serves as a proxy to the underlying Shader, providing a convenience mechanism for accessing both scalar and multi-dimensional shader input parameters directly as simple named properties.

To set a simple scalar shader input parameter, such as of type FLOAT or INT, you can refer to the property directly, for example, myFilter.radius.

To set or animate an individual component of a multidimensional shader input parameter, such as FLOAT2, you can use a property suffix convention to access the individual value directly. The following code shows two ways to set the first and second components of the FLOAT2 property center:

     // 'center' is an input parameter of type FLOAT2.
     shader.center = [10,20];
 

     // Use property suffix convention to access the first and second component of 'center'. 
     shader.center_x = 10;
     shader.center_y = 20;
 

The full set of supported property suffixes that you can use are as follows:

• For shader input parameters of type BOOL2, BOOL3, BOOL4, FLOAT2, FLOAT3, FLOAT4, INT2, INT3, or INT4, you can use "r g b a", "x y z w", or "s t p q" to access the 1st, 2nd, 3rd and 4th component, respectively.
• For shader input parameters of type MATRIX2x2, MATRIX3x3, or MATRIX4x4, you can use "a b c d e f g h i j k l m n o p" to access the 1st - 16th component of a given matrix, respectively.

As properties on the ShaderFilter change (such as during animation), the ShaderFilter automatically reapplies itself to the filters array of the visual component it is applied to.
