使用Java的DirectX程序的屏幕截图 [英] Screen Capture of DirectX programs with Java

问题描述

我编写了一个Java应用程序，该应用程序使用java.awt.Robot来捕获屏幕的屏幕截图，并且想知道是否可以使用DirectX/OpenGL捕获程序吗?

I wrote a Java application that uses the java.awt.Robot to take screen captures of the screen and was wondering if capturing a program using DirectX/OpenGL would be possible?

每次尝试执行此操作时，都会出现黑屏

Each time I try to do this, I get a black screen

推荐答案

是可以的.但也许仅在有限的情况下.

Yes it is possible. But maybe only in limited circiumstances.

我已经使用机器人一些关于实施的特定信息可能与您有所不同:

Some specific information about the implementation that may be different for you:

• 对createScreenCapture的调用是在OpenGL中完成的 应用.
• 该应用程序使用了重量级的GLCanvas
• 它使用了Java 6

• The call to createScreenCapture was done from within the OpenGL application.
• The application used heavyweight GLCanvas
• It used Java 6

确保将正确的坐标传递给它.您可以从 GraphicsEnvironment 获取屏幕坐标. a>

Make sure you pass it the correct coordinates. You can get the screen coordinates to use from the GraphicsEnvironment
