evidence of pixel grabbing?  RSS feed

I have been told that whenever I get information about a pixel (as with, for instance, robot.getPixelColor(coordinates) from awt) in an online applet or application, that applet will know that I am grabbing a pixel. I have also been told this is completely untrue. So I have two questions:

1) Is this correct? If I use something like a robot object, can the server know that I am storing individual pixel information, even though it is already giving me information about all pixels? (or if this information is not made available by default, could a program be written specifically to root out evidence of pixels being analyzed from afar?)

2) If it is correct, then is there some other way I can analyze pixels without sharing information about it, for instance by passively analyzing color information purely clientside somehow? I am open to roundabout suggestions, like taking a screenshot, and analyzing from the clipboard, etc., if something like that is possible. But a straight up java method that does not publicly share information about its existence would be ideal.

Don't get me started about those stupid light bulbs.
