ApplySourceAlpha |
For this one, we take the alpha channel of the source, and multiply it against the pixel values in the destination. Return the destination. |

NOT |
Operator 'NOT' is a logical operator for pixels. it will basically flip bits around 128 and create what looks like a negative image. The alpha channel is left unchanged. |

SourceCopy |
This is the most basic of operators. It simply returns the source color, which amounts to a copy over the destination pixel. |
SubtractColor |
Subtract a constant color. Stretch the results by adding 1.0 to the result of the addition and then dividing by 2.0. It takes more computation, but it ensures that the values will stay within the range of 0.0 -> 1.0 |
