AS3和PHP ...在本地保存屏幕截图并避免系统对话框？

Question

After drawing a bitmap of a display object, I need to save the bitmap, as well as text input, locally and avoid system dialogs that flash player would otherwise display while saving out. Can this be achieved with PHP? I've read that Air handles this task pretty effectively, but I'm rather inexperienced with both platforms. Any help would be greatly appreciated! thanks...

No you can't. Allowing webapps to save data on the local system without permission is a HUGE security risk (I could write a legitimate-looking webapp that saves spyware on your system). Flash disallows it for this reason.

Desktop-based (AIR) apps, however, can open a FileStream in the FileMode.WRITE mode and write data to it without any prompts from the user.

EDIT Since you are looking for a desktop based app, here are a few pointers:

var randomname:String=Math.floor(Math.random() * 1024).toString(16) + ".png"
var f:File=File.desktopDirectory.resolvePath("photos/" + randomname);
var s:FileStream=new FileStream();
s.open(f, FileMode.WRITE);
s.writeBytes(bytesArray); //bytesArray contains the binary data to write to the file
s.close();
