homography-transform/src/Plane.ts

A robust TypeScript implementation of homography-based transformation between 2D planes, ideal for computer vision and image mapping

export interface Point {
  x: number;
  y: number;
}

export class Plane {
  constructor(
    private readonly width: number,
    private readonly height: number
  ) {
    if (width <= 0 || height <= 0) {
      throw new Error('Plane dimensions must be positive numbers');
    }
  }

  public getWidth(): number {
    return this.width;
  }

  public getHeight(): number {
    return this.height;
  }

  public isPointInBounds(point: Point): boolean {
    return (
      point.x >= 0 &&
      point.x <= this.width &&
      point.y >= 0 &&
      point.y <= this.height
    );
  }

  public toString(): string {
    return `Plane(${this.width}x${this.height})`;
  }
}
