When I am trying to load this pdf http://merlin_test.s3.amazonaws.com/myPdf.pdf, it's unable to render all the contents. There is a blue background which is not visible and some of the texts are not visible as well as the color is not proper. Can someone please help

const transform = this.ctx.mozCurrentTransform;
    return [
      transform[0] * x + transform[2] * y + transform[4],
      transform[1] * x + transform[3] * y + transform[5],
    ];
  }
  isContentVisible() {
    for (let i = this.markedContentStack.length - 1; i >= 0; i--) {
      if (!this.markedContentStack[i].visible) {
        return false;
      }
    }
    return true;
  }
}
for (const op in OPS) {
  if (CanvasGraphics.prototype[op] !== undefined) {
    CanvasGraphics.prototype[OPS[op]] = CanvasGraphics.prototype[op];
  }
}
export { CanvasGraphics };
