| Attributes: |
| Name | Type | Description |
| bgcolor | float list[32] | The overlaid screen color alpha red green blue (default = 0. 0. 0. 0.) All values are in the range 0.-1. |
| colwidth | int | The width of the vertical band "gaps" in the screen. (default = 1) |
| ignore_zero | int |
Alpha channel mode (default = 0 (include alpha channel)) 0 = Luminance calculation includes the alpha channel 1 = Plane 0 is ignored and the luminance threshold calculation uses the RGB value |
| rowheight | int | The height of the horizontal band "gaps" in the screen. (default = 1) |
| thresh | float | The luminance threshold as an average of plane values (default = 0.) Input matrix values above this threshold are displayed as a grid of rectangular "gaps" between the overlaid horizontal and vertical screen stripes. Values below the threshold are displayed using the color specified by the bgcolor attribute. |
| xinterval | int | The spacing of "gaps" in the screen along the horizontal axis. (default = 1) |
| yinterval | int | The spacing of "gaps" in the screen along the vertical axis. (default = 1) |
