如何在python中将十六进制字符串转换为彩色图像? [英] How to convert hex string to color image in python?

问题描述

我是编程的新手，所以我对将字符串转换为彩色图像有一些疑问.

i'm new in programming so i have some question about converting string to color image.

我有一个数据，它由十六进制字符串组成，就像fff2f3 ..... 我想像这样将文件转换为png.

i have one data , it consists of Hex String, like a fff2f3..... i want to convert this file to png like this.

我可以通过此站点将十六进制数据转换为png图像. 但我不知道如何使用python代码将十六进制数据转换为png图像 但我尝试使用Image.frombytes('RGB',(1600,1059),hex_str)但 我不知道图像大小，所以我无法使用此方法.

i can convert the hex data to png image through this site but i don't know how to convert the hex data to png image using python code but i tried to use Image.frombytes('RGB',(1600,1059),hex_str) but i don't know image size , so i cannot use this method.

所以我的问题是我该如何将十六进制数据转换为图像使用python代码

so My question is how can i convert this hex data to image using python code

请给我一些建议，谢谢:)

please give me some advise , thank you :)

推荐答案

可以将十六进制字符串读入bytes对象，然后将该二进制文件写入.png文件中，如下所示:

Reading the hexadecimal string into a bytes object, and then writing that binary into a .png file can be done like this:

with open('binary_file') as file:
    data = file.read()

data = bytes.fromhex(data[2:])

with open('image.png', 'wb') as file:
    file.write(data)

并产生此结果，请记住它已损坏:

And produces this result, keep in mind it is corrupted:
