:: Takes the lesser of the source pixel's alpha or one minus the destination pixel's alpha and places it in the red, green, and blue fields of the specified pixel. This mode sets the specified pixel's alpha to be 1. | :: Takes the lesser of the source pixel's alpha or one minus the destination pixel's alpha and places it in the red, green, and blue fields of the specified pixel. This mode sets the specified pixel's alpha to be 1. (The red, green and blue channel are multiplied with the min(alpha_source, 1 - alpha_destination), alpha is multiplied by one. This can only be used for Source and will override the value set in Destination.) | ||
