PyMuPDF Pixmap tobytes()返回属性错误

Question

我正在关注the documentation并使用最新的PyMuPDF (1.18.13)。然而，Pixmap.tobytes()并不适合我：

zoom = 2    # zoom factor
mat = fitz.Matrix(zoom, zoom)
pix = page.getPixmap(matrix = mat)
stream = pix.tobytes(output="png")

AttributeError: 'Pixmap' object has no attribute 'tobytes'

文档示例：

这里的问题可能是什么？

我是PyMuPDF的维护者。您的配置是什么？我刚刚在Windows和Linux上分别使用v1.18.13测试了您的代码，它可以工作。
