A resolution is a dictionary with two subelement keys: units and pixelsPerUnit. The units key can be any of these strings: inch, cm, or pixels.The pixelsPerUnit key is a float data type. Types map identically. Security The RPC server restricts some operations to make sure that a client cannot use the RPC server maliciously to damage the user's system. The first security mechanism is that the RPC server binds to the loopback address, 127.0.0.1. This means all clients must run on the same computer as the RPC server and must connect to that computer through the loopback address. The second security mechanism prevents the exposure of "dangerous" classes that are normally on the Fireworks JavaScript DOM, such as the JavaScript Files classes. However, the client can still have Fireworks open, and export and save PNG and other image files. Third, certain methods and properties
