    Methods

    • Parameters

      • x: number
      • y: number
      • width: number
      • height: number

      Returns void

    • Draw a sub-renderer's content onto this renderer.

      The source image is read from image.canvas.

      Parameters

      • image: IRenderer
      • x: number
      • y: number
      • Optionalwidth: number
      • Optionalheight: number

      Returns void

    • Parameters

      • enableLegacyPip: boolean

      Returns void

    • Parameters

      • x: number
      • y: number
      • width: number
      • height: number

      Returns void

    • Parameters

      • text: string
      • x: number
      • y: number

      Returns void

    • Execute all buffered draw commands.

      Ordering contract: GPU-accelerated commands (drawImage, fillRect, strokeRect) are rendered first, then Canvas 2D helper operations (text/path) are composited on top. Callers must ensure fillText/strokeText are issued AFTER all drawImage calls within a single frame.

      Returns void

    • Returns string | CanvasGradient | CanvasPattern

    • Parameters

      • cpx: number
      • cpy: number
      • x: number
