<Opacity>: Optional real

Percentage of opacity that must be applied to <Source image> before performing the blend (100% by default, no opacity is applied).

<Image>.AlphaBlend blends the images and keeps the alpha channel of the destination image. Therefore, the alpha channel of the source image is not used.
