从字节文件打开PIL图像 [英] Open PIL image from byte file

问题描述

我有此图像，其大小为128 x 128像素，RGBA存储为字节值在我的记忆中.但是

I have this image with size 128 x 128 pixels and RGBA stored as byte values in my memory. But

from PIL import Image

image_data = ... # byte values of the image
image = Image.frombytes('RGBA', (128,128), image_data)
image.show()

引发异常

ValueError:图片数据不足

ValueError: not enough image data

为什么?我在做什么错了?

Why? What am I doing wrong?

推荐答案

您可以尝试以下操作:

image = Image.frombytes('RGBA', (128,128), image_data, 'raw')

源代码:

def frombytes(mode, size, data, decoder_name="raw", *args):
    param mode: The image mode.
    param size: The image size.
    param data: A byte buffer containing raw data for the given mode.
    param decoder_name: What decoder to use.
