Taking screenshot with java applet using java robot class not working

873616

Hi Everyone,

I am using the java applet to take screenshot of the web browser using the java's robot class.
Robot objRobot = new Robot ();
BufferedImage objBufferedImage = objRobot.createScreenCapture(objRectArea);

The thing work good in windows system taking screenshot but in case of mac osx i get the blank image.When i check the event viewer in mac osx i get the following error.

invalid context
invalid pixel format
CoreAnimation: rendering error 506

The problem is coming for all the browser safari,firefox and chrome.My applet is signed applet.


What might be the reason.An early reply is very valuable.

My machine configuration is as follows.

OS : MAC OSX
Version : 10.6.4

Is that a system level issue , java plugin issue?I'am confused with this error.

Thanks sagar.

Hm, seems like the Mac implementation of the Robot class is doing some bad initializations there. I can't be a 100% sure of course, but this smells like a bug to me. Are you sure you have the latest version of Java installed?
