sFunction | Integer that
specifies or receives one of the following possible values:0 | Default. CLEAR. Perform no operation.
| 1 | MIN. Compare the brightness of each pixel in both images, and show the less bright of the two pixels. | 2 | MAX. Compare the brightness of each pixel in both images, and show the brighter of the two pixels. | 3 | A. Display only Input A. | 4 | A OVER B. Display Input A over Input B. All of Input A is visible, and Input B shows through translucent regions of Input A. | 5 | A IN B. Display all parts of Input A that are contained in Input B. Only regions with nonzero alpha values for both images are visible, and no part of Input B shows through. | 6 | A OUT B. Display all parts of Input A that are not contained in Input B. No part of Input B is displayed. | 7 | A ATOP B. Display Input A covering Input B, with each sample scaled by the alpha channel of Input B. | 8 | A SUBTRACT B. Display Input A with the sample color values of Input B subtracted from the corresponding sample color values of Input A. The resulting color is scaled by the alpha values of Input A. | 9 | A ADD B. Display Input A with the sample color values of Input B added to the corresponding sample color values of Input A. The resulting color value is scaled by the alpha value of Input A. | 10 | A XOR B. Display pixels of each set of input where the two images do not overlap. Pixels that overlap are scaled by their inverse alpha value. | 19 | B. Display only Input B. | 20 | B OVER A. Display Input B over Input A. All of Input B is visible, and Input A shows through translucent regions of Input B. | 21 | B IN A. Display all parts of Input B that are contained in Input A. Only regions with nonzero alpha values for both images are visible, and no part of Input A shows through. | 22 | B OUT A. Display all parts of Input B that are not contained in Input A. No part of Input A is displayed. | 23 | B ATOP A. Display Input B over Input A, with each sample scaled by the alpha channel of Input A. | 24 | B SUBTRACT A. Display Input B with the sample color values of Input A subtracted from the corresponding sample color values of Input B. The resulting color is scaled by the alpha values of Input B. | 25 | B ADD A. Display Input B with the sample color values of Input A added to the corresponding sample color values of Input B. The resulting color value is scaled by the alpha value of Input B. |
