| Value | Description |
| keep | Stencil buffer pixels will not be changed by draws. |
| zero | Stencil buffer pixels will be set to zero. |
| replace | Stencil buffer pixels will be replaced with a custom value. |
| increment | Stencil buffer pixels will be incremented each time they're rendered to. |
| decrement | Stencil buffer pixels will be decremented each time they're rendered to. |
| incrementwrap | Similar to increment, but will wrap around to 0 when it exceeds 255. |
| decrementwrap | Similar to decrement, but will wrap around to 255 when it goes below 0. |
| invert | The bits in the stencil buffer pixels will be inverted. |
