我可以使用C / C ++控制投影机梯形校正吗？ [英] Can I control projector keystone using C/C++?

问题描述

我在使用Window XP的PC上运行程序。 PC连接到三台投影机。现在，我想控制投影仪的基石，或者不是通过物理按钮触摸获得相同的结果，而是使用我的程序中的程序语言。

如果有功能可以让我知道吗？



提前谢谢。

I have a program running on the PC with Window XP. The PC is connected to three projectors. Now, I'd like to control keystone of the projectors or get same result not by physical button touch but by using program language from my program.
Can anyone let me know if there is function for this?

Thanks in advance.

推荐答案

在不知道软件或投影机的品牌的情况下，它是不可能说有一个提供此功能的可用SDK。完全有可能没有规定控制投影仪的这个方面。



我假设PC和投影仪之间的连接包括某种形式的USB /串行/并行端口链接。如果你只通过视频/音频线连接，你绝对可以忘记它。除非有一些（可能）未记录的功能允许通过特殊形成的图像或声音控制投影机。



- 我之前有一个iPod，我也有一个FM发射器。有趣的是，为了改变发射机所播放的频率，你必须选择一个特定的音频文件并播放它！（在适当的国家为每个FM频段的0.1MHZ提供一个文件!! - 大约200个文件）发射器很聪明，意识到轨道不是声音，而是控制信号。





虽然总结一下 - 说实话，我会非常惊讶。

Without knowing the software, or the brand of the projectors, it's impossible to say that there is an available SDK that provides this functionality. It's entirely possible that no provision has been made to control this aspect of the projectors.

I'm assuming that the connection between the PC and the projectors includes some kind of USB/serial/parallel port link. If you're only connected via video/audio cables, you can absolutely forget about it I'd say. Unless there is some (probably) undocumented feature that allows control of the projector via specially formed images or sounds.

- I had an iPod eons ago that I also had an FM transmitter for. The interesting thing was, that in order to change the frequency that the transmitter broadcast at, you had to pick a specific audio file and play it!!(one file provided for each 0.1 MHZ of the FM band in the appropriate country!! - About 200 files) The transmitter was clever enough to realize that the 'track' wasn't sound, but control signals.


Though, to summarise - I'd be pretty surprised to be honest.

通常可以通过串口和局域网连接由PC控制投影机。

如果你的话投影机支持PJLink，您可以使用下面的示例C＃程序：

Usually the projector can be controlled by PC via Serial Port and LAN connection.
If your projector is support PJLink, you can use sample C# program below:
