feBlend Mode Details

feBlend Modes are defned as follows

normal mode (no blending)

α_{out} = 1 - (1- α_{in1}) (1- α_{in2})

α_{out} \times C_{out} =(1-α_{in2}) α_{in1} C_{in1} + α_{in1} C_{in1}

multiply blend mode

α_{out} = 1 - (1- α_{in1}) \times (1- α_{in2)}

α_{out} \times C_{out} = (1-α_{in2}) α_{in1} C_{in1} + (1-α_{in1}) α_{in2} C_{in2} + α_{in1} α_{in2} C_{in1} C_{in2}

screen blend mode

α_{out} = 1 - (1- α_{in1}) \times (1- α_{in2)}

α_{out} \times C_{out} = α_{in1} C_{in1} + α_{in2} C_{in2} + α_{in1} α_{in2} C_{in1} C_{in2}

darken blend mode

α_{out} = 1 - (1- α_{in1}) \times (1- α_{in2)}

α_{out} \times C_{out} = min( (1-α_{in1}) α_{in2} C_{in2} + α_{in1}C_{in1}, (1-α_{in2}) α_{in1} C_{in1} + α_{in2}C_{in2} )

lighten blend mode

α_{out} = 1 - (1- α_{in1}) \times (1- α_{in2)}

α_{out} \times C_{out} = max((1-α_{in1}) \times α_{in2} C_{in2} + α_{in1}C_{in1},(1-α_{in2}) \times α_{in1} C_{in1} + α_{in2}C_{in2})
