Flash/flex Study Notes (5): capture the camera (continued)-capture the screen online and save it to the client

A camera is required for normal playback.

Ideas:

Using the camera and online screen capture in the previous Flash/flex learning note (2): capture the camera has already been mentioned, so do not paste it again. As for saving files on the client, flash is also very simple to use: directly call filereference can be, in order to reduce the image size, may also use as3.0 extension Library (Project address http://code.google.com/p/as3corelib ), convert the location of the BMP format to JPEG and save it.

 

Extension:

Combined with the methods described in this article and the flash/flex learning notes (4): how to open a webpage and get/post data, you can easily make "online dashboard" or "online generation of membership headers" and other functions.
