See swf-version and target-player options for MXMLC
Tanx, But I must keep my current version of Flash Player and I'm not able to change swf-version or target-player through compiler settings arguments or etc... I just need these feature for BitmapData.
Can I use something like this to check if my object has new methods of Flash Player or not:
Is there any new method for BitmpaData class in Flash player 11, to check it based on that?!
I believe the swf-version dictates what APIs are available at run time.
In my experience, an older player will run SWFs with newer swf-versions. You just don’t want to require that newer version in the html wrapper.
