Pixie is a magnifying glass utility for Mac OS X. It is useful for doing pixel-perfect layout, checking the correctness of graphics and UI, and getting magnified screen shots. It has a bunch of power features to make life easier, including:

• Variable magnification

• Support for grids of different colors

• Copying and saving a magnified image

• Display of mouse coordinates

• Continuous refreshing to follow animations

• Floating above other windows for accessibility

• Locking the contents of the magnified view

• Locking one axis of the magnified view at a time

• Dragging, copying and display of colors

To change settings, just bring up the Preferences panel. To change the size of the magnified area, resize the window using the lower right hand corner.

To drag, copy and display colors from the magnified view, first lock the magnified view (press Command-L), then move the mouse to the pixel you want and click or drag it. (You may need to turn some of these features on in Preferences before they will work).
