GIMP 似乎在 2 个目录中查找插件。一个是C:\Program Files\GIMP 2\lib\gimp\2.0\plug-insC:\Users\Sam\AppData\Roaming\GIMP\2.10\plug-ins
但是，当我查看plug-ins文件夹时，所有内容都是独立的可执行文件，没有 Python 脚本。
我找到了一个我想运行的 Python 脚本。作者说只需将 Python 源代码文件粘贴到plug-ins文件夹中，然后就可以通过菜单在 GUI 中访问该脚本。考虑到文件夹Xtns/Utils中已有的其他内容，这似乎不对plug-ins

答案1
在 Windows 上，Gimp 自 2.8 版起就内置了 Python 支持。要检查它是否正常工作，请执行以下操作：
- 你应该有菜单
Filters>Python-fu>Console - 它应该打开一个 Python 控制台。
- 你还应该滤镜>装饰>雾（2.10）或文件管理器>渲染>云>雾（2.8，根据记忆）。
另一方面，您的过滤器似乎非常老旧（2005 年，因此与 Gimp 2.2 是同一时期的）。上面的代码不完整，完整代码超过 3800 行（检索到的这里）。
此完整代码已正确注册，但 Gimp 不再允许菜单位置，因此实际菜单位置是滤镜>实用工具>拼接全景图。
该插件从 Gimp 2.10 开始，但我没有进一步测试。这个插件在 2005 年可能很有用，但现在全景拼接用胡金。
