Methods
-
addToWorld(x, y, width, height, anchorX, anchorY) → {Phaser.Image}
-
Creates a new Phaser.Image object using a blank texture and assigns this Filter to it. The image is then added to the world.
If you don't provide width and height values then Filter.width and Filter.height are used.
If you do provide width and height values then this filter will be resized to match those values.
Parameters:

0 The x coordinate to place the Image at.
y
number <optional>
0 The y coordinate to place the Image at.
width
number <optional>
The width of the Image. If not specified (or null) it will use Filter.width. If specified Filter.width will be set to this value.
height
number <optional>
The height of the Image. If not specified (or null) it will use Filter.height. If specified Filter.height will be set to this value.
anchorX
number <optional>
