Step Four: ActionScript Code Hints

Much of the ActionScript in the previous section is reasonably straight forward but there is one section which could be confusing and is critical to understand if you want to get the most out of filters. This is the section of code that defines how the filter will look:

(0xff00ff,1,25,25,2,3,false,false)

Code hinting includes information to help you achieve the correct syntax. The following shows you how to use the code hints.

Note: The hint in bold refers to the parameter where the cursor is located. In the above example the cursor is located in the section referring to the filter's color:

The code hint tells you:
