Overview
A checkerboard generator — for checking transforms, aspect, and filtering.

- Set
sizein pixels and the two colours; the format knobs set the frame. - Use it to check transforms, aspect and filtering — a checker that swims shows a bad resample.

Parameters
| Parameter | Type | Default | What it does |
|---|---|---|---|
| size | Float | 64.0 | Square size in pixels. |
| color0 | Color | [0.1, 0.1, 0.1, 1.0] | The first colour. |
| color1 | Color | [0.5, 0.5, 0.5, 1.0] | The second colour. |
| format_width | Int | 1920 | Width in pixels. |
| format_height | Int | 1080 | Height in pixels. |
| pixel_aspect | Float | 1.0 | Pixel width ÷ height. 1 = square; 2 = anamorphic 2× squeeze. The viewer and every filter honour it, so a squeezed plate looks right and resamples right. |
| disabled | Bool | false | Bypass: the node passes its first input through untouched (D in the graph). The knobs keep their values for when it comes back. |
| label | Text | A note shown under the node in the graph — what this node is FOR. Never affects the render or the cache. |
