Function clipFromGrid

clipFromGrid(
    input: {
        columns: number;
        count?: number;
        frameDuration?: number;
        frameDurations?: readonly number[];
        frameHeight: number;
        frameWidth: number;
        indices?: readonly number[];
        loop?: AnimationLoopMode;
        margin?: number;
        rows?: number;
        source: TextureSource;
        spacing?: number;
    },
): Promise<SpriteAnimationClip>
Slice a grid-arranged sprite sheet into a clip. Use when you don't have a TexturePacker JSON — just an image and uniform cell dimensions. Cells are walked row-major.

Specify exactly one of rows, count, or indices to define the cell set (along with columns). Combining count and indices is rejected.

Returns a Promise because pixi.js is imported lazily — keeps the static module graph free of a runtime pixi dependency for consumers who only use the sheet-based helpers.
Parameters
- input: {
      columns: number;
      count?: number;
      frameDuration?: number;
      frameDurations?: readonly number[];
      frameHeight: number;
      frameWidth: number;
      indices?: readonly number[];
      loop?: AnimationLoopMode;
      margin?: number;
      rows?: number;
      source: TextureSource;
      spacing?: number;
  }
  - columns: number
  - Optionalcount?: number
    Number of cells to use, walked row-major. Mutually exclusive with indices.
  - OptionalframeDuration?: number
  - OptionalframeDurations?: readonly number[]
  - frameHeight: number
  - frameWidth: number
  - Optionalindices?: readonly number[]
    Explicit row-major, 0-based cell indices. Mutually exclusive with count.
  - Optionalloop?: AnimationLoopMode
  - Optionalmargin?: number
    Pixels around the sheet edge.
  - Optionalrows?: number
  - source: TextureSource
  - Optionalspacing?: number
    Pixels between cells.
Returns Promise<SpriteAnimationClip>
Example
```
const tex = await Assets.load<Texture>('/coin.png');
  const clip = await clipFromGrid({
    source: tex.source,
    frameWidth: 16, frameHeight: 16,
    columns: 8, count: 8,
    frameDuration: 1 / 10,
  });
```
