我正在使用我在这里找到的代码：http: //svn.python.org/projects/python/branches/pep-0384/Demo/tkinter/ttk/roundframe.py它给了我圆角的框架。（这是Bryan Oakley相关文章的链接）。但是，我想为使用该样式生成的框架的背景着色。

"""Ttk Frame with rounded corners.

Based on an example by Bryan Oakley, found at: http://wiki.tcl.tk/20152"""

在我看来，该文件的作用是将图像应用为样式表，而该图像是巨大的文本块。因此，当我尝试给样式本身或框架背景颜色时，Python 会返回我：_tkinter.TclError: unknown option "-bg".

我认为解决方案是更改图像。经过一番研究，我发现显然 PhotoImage 类将“base64 编码的 GIF 文件”作为字符串，现在，我该如何解码，或者，我将提供什么图像格式 PhotoImage 以便我可以适当地更改框架？

您可以使用base64.decodestring对编码图像进行解码。

import base64

with open('frameBorder.gif', 'wb') as f:
    decoded = base64.decodestring(b"""

    f.write(decoded)

更改解码的文件frameBorder.gif，并使用以下代码将其编码回来。

（以下代码输出base64编码的字符串）

import base64

with open('frameBorder.gif', 'rb') as f:
    encoded = base64.encodestring(f.read())
    print(encoded.decode('latin1'))
