PixelLogger

PixelLogger is my crude cross-platform replacement for FreeRuler, which was a wonderful early Mac OS X program for locating pixels on the screen, but doesn't run on the latest Mac OS X.

Download the .jar file and double-click it! It's tiny eh? When you run it you'll see a simple window containing a log of coordinates and the current coordinate at the bottom.

Whenever you move to different locations on the screen, the coordinates will update (at 25 frames per second - it's not going to use up your CPU :-) ). If you bring the application to the front, then it will log coordinates whenever you press Enter.

Scroll bars appear after you've logged a number of coordinates and you can scroll up and down or enlarge the window to see the rest of them. You can copy the log by selecting the text and pressing Command-C (Control-C in Windows/Linux). You can quit the program at any time. Enjoy.

The program is GPLv3 open-source and the source code can be found in the jar file itself (duplicate the .jar file, rename it a .zip file and extract the contents). Great!
