Defines a shader fill. Use a GraphicsShaderFill object with the Graphics.drawGraphicsData() method. Drawing a GraphicsShaderFill object is the equivalent of calling the Graphics.beginShaderFill() method.

Constructor

new (shader:Shader, ?matrix:Matrix)

Creates a new GraphicsShaderFill object.

Parameters:

shader

The shader to use for the fill. This Shader instance is not required to specify an image input. However, if an image input is specified in the shader, the input must be provided manually by setting the input property of the corresponding ShaderInput property of the Shader.data property.

matrix

A matrix object (of the openfl.geom.Matrix class), which you can use to define transformations on the shader.

Variables

matrix:Matrix

A matrix object (of the openfl.geom.Matrix class), which you can use to define transformations on the shader. For example, you can use the following matrix to rotate a shader by 45 degrees (pi/4 radians):

var matrix = new openfl.geom.Matrix();
matrix.rotate(Math.PI / 4);

The coordinates received in the shader are based on the matrix that is specified for the matrix parameter. For a default (null) matrix, the coordinates in the shader are local pixel coordinates which can be used to sample an input.

shader:Shader

The shader to use for the fill. This Shader instance is not required to specify an image input. However, if an image input is specified in the shader, the input must be provided manually by setting the input property of the corresponding ShaderInput property of the Shader.data property. When you pass a Shader instance as an argument the shader is copied internally and the drawing fill operation uses that internal copy, not a reference to the original shader. Any changes made to the shader, such as changing a parameter value, input, or bytecode, are not applied to the copied shader that's used for the fill.
