Web7 mei 2024 · 1. PIL image转换成array 当使用PIL.Image.open()打开图片后，如果要使用img.shape函数，需要先将image形式转换成array数组 img = numpy.array(image) 或者 img = np.asarray(image) array和asarray都可将结构数据转换为ndarray类型。但是主要区别就是当数据源是ndarray时，array仍会copy出一个副本，占用新的内存，但asarray不会。 Web2 okt. 2024 · If the NumPy array has the shape (height, width, 3) it will automatically create an RGB image. We can then use the PIL function save to save the image. By default, the image type will be based on the file extension, so in this case, it will be a PNG image. PIL creates an RGB image by default because the array has 3 colour channels.
