Class ColorPaintBuffer

constructor

• new ColorPaintBuffer(
      config: PixelEngineConfig,
      tilePool: TilePool<PixelTile>,
      blendPixelDataFn?: (
          target: PixelData32,
          src: PixelData32,
          opts?: PixelBlendOptions,
      ) => boolean,
  ): ColorPaintBuffer

  Parameters

  • config: PixelEngineConfig
  • tilePool: TilePool<PixelTile>
  • blendPixelDataFn: (target: PixelData32, src: PixelData32, opts?: PixelBlendOptions) => boolean = blendPixelData
    • • (target: PixelData32, src: PixelData32, opts?: PixelBlendOptions): boolean

      • Blits source PixelData into a destination PixelData using 32-bit integer bitwise blending. This function bypasses standard ImageData limitations by operating directly on Uint32Array views. It supports various blend modes, binary/alpha masking, and automatic clipping of both source and destination bounds.

        Parameters

        • target: PixelData32
        • src: PixelData32
        • Optionalopts: PixelBlendOptions

        Returns boolean

        Example

        const dst = new PixelData(ctx.getImageData(0,0,100,100))
        blendImageData32(dst, sprite, {
          blendFn: COLOR_32_BLEND_MODES.multiply,
          mask: brushMask,
          maskType: MaskType.ALPHA
        });
        Copy
