This section determines how the source and destination functions are combined. Options are as follows: | This section determines how the source and destination functions are combined. Options are as follows: | ||
''Add'' - (Result = Source + Destination) | ''Add'' - (Result = Source + Destination) (This blend mode simply adds pixel values of one layer with the other. In case of values above 1 (in the case of RGB), white is displayed.) | ||
''Subtract'' - (Result = Source - Destination) | ''Subtract'' - (Result = Source - Destination) (This blend mode simply subtracts pixel values of one layer with the other. In case of negative values, black is displayed.) | ||
''Reverse Subtract'' - (Result = Destination - Source) | ''Reverse Subtract'' - (Result = Destination - Source) (Difference subtracts the top layer from the bottom layer or the other way round, to always get a positive value. Blending with black produces no change, as values for all colors are 0. (The RGB value for black is 0,0,0). Blending with white inverts the picture.) | ||
''Minimum'' - (Result = MIN(Source, Destination)) | ''Minimum'' - (Result = MIN(Source, Destination)) (Creates a resultant pixel that retains the smallest components of the foreground and background pixels.) | ||
''Maximum'' - (Result = MAX(Source, Destination)) | ''Maximum'' - (Result = MAX(Source, Destination)) (Selects the maximum of each component from the foreground and background pixels.) | ||
