编码和解码与pyglet一起使用的.gif文件，并使用pyinstaller制作成.exe文件

Posted 2021-04-12

我想用pyinstaller将.gif文件烘焙到.exe中。根据我的研究，我必须将gif编码为字符串并解码该字符串以实现此目的。编码字符串并解码字符串是有效的。尝试将其用作pyglet中的动画资源时出错。编码解码中的东西打破了gif？如果有另一种首选方式，请告诉我！

步骤1

import base64

with open("test.gif", "rb") as imageFile:
    image = base64.b64encode(imageFile.read())
    print(image)

第2步

将此字符串保存在.py文件中，如下所示：

image = b'AWggsegsegs/....'

第三步：

import pyglet
import base64
from gif_string import image


decodedgif = base64.b64decode(image) # Works this far
animation = pyglet.resource.animation(decodedgif) # Error here
sprite = pyglet.sprite.Sprite(decodedgif)

错误消息读取

  Ensure that the filename has the correct captialisation.

答案

而不是只能加载文件的pyglet.resource.animation()，你应该使用pyglet.image.load_animation()。它的可选File参数支持file-like objects，所以你应该使用io.BytesIO()构造一个并将其传递给那里。
