Sol Robots has released Pixel Tools for Mac OS X 10.6 or higher. It’s available for US$2.99 at the Mac App Store. Pixel Tools is designed as a companion for designers and anyone that needs to make pixel precise measurements, get the numeric value of a color, or magnify a portion of any screen.
Pixel Tools starts with an “intelligent” magnifier, whose view stays centered on your current mouse position and can magnify up to 64 times normal size. For screen measuring, Pixel Tools comes equipped with pixel accurate rulers that dynamically scroll as you move your mouse. For the designer’s convenience, the Pixel Tools app window floats above other windows and its keyboard shortcuts are globally accessible by holding down control-option-command while initiating the shortcut.
