| Name | Type | g/s | Description |
|---|---|---|---|
| anchor_x | int | The horizontal anchor point for rotation (default = 0) The anchor point is horizontally offset in pixels from the upper left corner of the display. | |
| anchor_y | int | The vertical anchor point for rotation (default = 0) The anchor point is vertically offset in pixels from the upper left corner of the display. | |
| boundmode | int | Boundary handling mode (default = 0 (ignore)) 0 = ignore: Values that exceed the limits are ignored. 1 = clear: Values that exceed the limits are set to 0. 2 = wrap: Values that exceed the limits are wrapped around to the opposite limit with a modulo operation. (256 wraps to 0, 257 wraps to 1, and -1 wraps to 255, -2 wraps to 254, etc.) 3 = clip: Values are limited not to exceed min or max. (e.g. numbers greater than 255 are set to 255, and numbers less than 0 are set to 0.) 4 = fold: Values that exceed the limits are folded back in the opposite direction. (256 is folded back to 254, 257 is folded back to 253, and -1 is folded back to 1, -2 to 2, etc.) |
