Drawing Inches for our ruler

It's time that we start drawing our actual ruler. The first step is we need to figure out what an inch is at all. As we talked about in Course 2 when we discovered the capabilities class we discovered that we can load up how many pixels are in an inch using the Capabilities.screenDPI property.

Now that we know how many pixels are an inch its time for us to draw lines in the intersection point of inches. By the end of this video you will leverage Flashes Drawing API(you can learn more about that here) to draw out the inches of our ruler.
