OS X Mavericks introduced a user preference to allow screens to have separate spaces. How PixelStick behaves when you have more than one screen depends on your version of macOS/OS X. Click the locks or hold down the shift key to constrain the distance or angles. Drag the endpoints to change the distance or angle. “ If it can’t be expressed in figures, it is not science. Since there is no standardized scale for arbitrary documents on the Mac, for other documents you can create customized scaling options in PixelStick that it can use in its measurements. Out of the box its measurements will work with Google Maps, Yahoo Maps and Photoshop. In addition it does scaling so if you know the scale of a document you can measure its contents. PixelStick is a utility that allows easily measuring distances and angles on your screen, zooming in under the cursor to show colors and allows copying those colors in 7 formats (CSS, HTML and several RGB integer and hex variations) in any application, window and across the desktop. “ Not everything that counts can be counted and not everything that can be counted counts.” – Albert Einstein

Custom scales are available are available in PixelStick and can be used by astronomers, microbiologists, etc. On that map cities that are 5″ apart are 5 miles from one to the other. In a map you can look at the bottom right and see the scale which might be 1 in/1 mile. It is the same as the use of scale in a map. In this way PixelStick can measure distance between galaxies planets, countries, cities, people, molecules, atoms or various sub-atomic particles in a photo if the scale is known. The relation between pixels and whatever you are measuring is scale. PixelStick measures pixels and the distance between pixels. – William Thomson, Lord KelvinĪccurate measurement is essential in many fields, and all measurements are necessarily approximations. When you can measure what you are speaking about, and express it in numbers, you know something about it, when you cannot express it in numbers, your knowledge is of a meager and unsatisfactory kind it may be the beginning of knowledge, but you have scarcely, in your thoughts advanced to the level of Science. Measurement can be defined as the comparison of an unknown quantity of some physical quality/dimension/phenomenon with a known, pre-selected value of the same physical quality/dimension/phenomena, called the Unit so that we can find out how many iteration or fractions of the unit are contained in the unknown quantity Or so that we can find out how many repeations of the unit equals the unknown quantity. … So that we can find out how many repeations of the unit equals the unknown quantity. So that we can find out how many iteration or fractions of the unit. a known, pre-selected value of the same physical quality/dimension/phenomena, called the Unit. …an unknown quantity of some physical quality/dimension/phenomena… “ Man is the measure of all things” – Protagoras It can also be captioned with this quote. Da Vinci’s Vitruvian Man illustrates the ratios of the dimensions of the human body a human figure is often used to illustrate the scale of architectural or engineering drawings. PixelStick works in any app, between app, in the Apple Finder in addition it is lightweight, handy, fast and inexpensive. Excellent for designers, navigators, mapmakers, biologists, astronomers, cartographers, graphic designers or anyone who uses a microscope or telescope or wants to measure a distance on their screen in any window or application. PixelStick is a sophisticated ruler, protractor and eyedropper that works anywhere that you do on your Mac. Photoshop has distance, angle and color tools but they only work in Photoshop. PixelStick is a tool for measuring distances (in pixels), angles (in degrees) and colors (RGB) on the screen.
