Detailed Description

wrapper for java.awt.Robot

All method IDs are calculated at startup and cached

Method IDs are independent of the current environment and thread. Therefore there's no problem with caching them.

References JVM::DetachCurrentThread().

int Robot::GetPixelRGB	(	int	x,
		int	y
	)

get the color of the screen of the given position

Parameters

x	horizontal position in screen coordinates
y	vertical position in screen coordinates

The origin of the screen coordinate system is the upper left corner of the screen.

Definition at line 159 of file Robot.cpp.

References JVM::GetEnv(), getPixelColorMID, getRGBMID, and robot.

IplImage * Robot::GetScreenCapture	(	int	left,

left, top, right, bottom are the corners of the rectangle in screen coordinates

The origin of the screen coordinate system is the upper left corner of the screen.

The capture is returned as an IplImage* for the use with OpenCV

Warning: You have to release the returned image after you have used it. Otherwise the memory held by this structure will never be freed.
