@Mooncrater我相信它是这样的:`stream = io.BytesIO(img_byte_array)`然后`img = Image.open(stream)` (2认同) Chr*_*van 9 我认为您可以简单地调用 PIL 图像的.tobytes()方法,然后使用bytes内置函数将其转换为数组。 #assuming image is a flattened, 3-channel numpy array of e.g. 600 x 600 ...

plt.title('The color image to gray image') plt.show() 使用函数convert()来进行转换,它是图像实例对象的一个方法,接受一个 mode 参数,用以指定一种色彩模式,mode 的取值可以是如下几种: · 1 (1-bit pixels, black and white, stored with one pixel per byte) ...
