我正在尝试使用 Python 将 Illustrator 文件另存为 .eps。据我所知，Illustrator 通常不支持 Python，因此我下载了一个参考文件并将其导入到我的代码中。通常代码与 Illustrator 中使用的 javascript 非常相似。
我收到的错误是：
回溯（最近一次调用最后一次）： 文件“s:\Workstation - DavidK\Code\Main\SAVETEST.py”，第 12 行，位于
doc.SaveAs(SaveIn = 'S:/Workstation - DavidK/Code/Main/DeleteLater/tempSheet.eps', 选项 = saveOpts)
文件“s:\Workstation - DavidK\Code\Main\illustrator_ref.py”，第 1998 行，另存为
return self._oleobj_.InvokeTypes(1398161747, LCID, 1, (24, 0), ((8, 1), (12, 17)),SaveIn
TypeError: Objects of type 'EPSSaveOptions' can not be converted to a COM VARIANT (but obtaining the buffer() of this object could)
我尝试过使用缓冲区，但我使用的是Python3，所以它必须需要内存视图，这需要字节，我根本不明白。
这是我的代码：
from illustrator_ref import *
import win32com.client as win32
from win32com.client import DispatchBaseClass
from win32com.client import CoClassBaseClass
app = win32.GetActiveObject("Illustrator.Application")
doc = app.activeDocument
saveOpts = EPSSaveOptions(CoClassBaseClass)
saveOpts.EmbedAllFonts = True
saveOpts.SaveMultipleArtboards = True
doc.SaveAs(SaveIn = 'S:/Workstation - DavidK/Code/Main/DeleteLater/tempSheet.eps', Options = saveOpts)
这是我无法理解的 illustrator_ref 代码：
# This CoClass is known by the name 'Illustrator.EPSSaveOptions.24'
class EPSSaveOptions(CoClassBaseClass): # A CoClass
# Options which may be supplied when saving a document as an Illustrator EPS file

如果您使用 win32com.client 中的 Dispatch 方法，并且知道您正在使用的对象的名称，您可以在 python 中创建 illustrator 对象，并将它们与其他对象一样对待。这是我编写的一个简单程序，在 python 3.12.0 和 Win 10 中运行，它展示了它是如何完成的，希望这有所帮助：
