Photoshop COM和C ++（操作方法）

[英]Photoshop COM and C++ (How to)

原文 2012-01-30 21:40:15 5 1 c++/ com/ photoshop

I would like to use Photoshop via COM using C++, but I'm not sure if I'm getting it right. 我想使用C ++通过COM使用Photoshop，但是不确定是否正确。 I've seen lot's of tutorials on how to do that with C# and even tried one but as far as I know ideology of COM says that you can use any language you like since it's source is just binary. 我看过很多关于如何使用C＃进行操作的教程，甚至尝试过其中一个，但据我所知，COM的意识形态说，您可以使用任何喜欢的语言，因为它的源代码只是二进制。 So, C++ is exactly what I want and to start I should have a photoshop interface class in my client programm, right ? 所以，C ++正是我想要的，开始时，我应该在客户端程序中有一个photoshop接口类，对吗？ So, the question is: Where can I get it (interface class) ? 因此，问题是：在哪里可以得到它（接口类）？ And even if I had one, how would I know about functions to operate photoshop instance. 即使我有一个，我也将如何了解操作Photoshop实例的功能。 Or maybe I understanding COM + C++ wrong ? 还是我理解COM + C ++错误？ Your help is highly appreciate. 非常感谢您的帮助。

Thank you in advance! 先感谢您！

You are right, COM is language-neutral, but it requires a lot of extra runtime work to ask the OS for pointers to the interfaces and methods you need. 没错，COM是与语言无关的，但是它需要大量额外的运行时工作才能要求OS提供指向所需接口和方法的指针。 COM is a huge pain in C++. COM是C ++的巨大痛苦。 You're looking at 5-10 lines of code for a single function call. 您正在为一个函数调用查看5-10行代码。 Microsoft's "helper" libraries like MFC and ATL can help make it easier, but it's still not pretty. 微软的“帮助器”库，例如MFC和ATL可以使它变得更容易，但是它仍然不是很漂亮。

C# abstracts a lot of the details away and makes COM look like regular object-oriented code. C＃提取了许多细节，并使COM看起来像常规的面向对象的代码。 In C++, you'd have to write the wrapper class yourself or find someone else's implementation. 在C ++中，您必须自己编写包装器类或找到其他人的实现。 It won't necessarily be hard, but it will be tedious. 这不一定很困难，但是会很乏味。

I work with COM in C++ and I would jump at the chance to do it with C# instead. 我在C ++中使用COM，所以我会抓住机会用C＃代替。
