I'm making a small app where children can fill preset illustrations with colours. I've succesfully implemented an MS-paint style paint bucket using the flood fill argorithm. However, near the edges of image elements pixels are left unfilled, because the lines are anti-aliased. This is because the current condition on whether to fill is colourAtCurrentPixel == colourToReplace , which doesn't work on the blended pixels at the lines. (the colours are RGB uints) I'd like to add a smoothing/treshold option like in Photoshop and other sophisticated tools, but what's the algorithm to determine the

I would like to make a Flash video player that takes a URL as an attribute when you embed it and loads the video based upon that attribute. All I need for the moment is a play/pause button. How can I do this is AS3? It needs to be able to play F4V files. If it's simple to make other features, like full screen, showing how much of the video has been loaded on the timeline, or being able to click at any point in the timeline yo jump to that point in the video, please tell how! Thank you so much! Making your own from scratch is inventing the wheel. if your doing it as a side project, that's fine

I want to use the Charmless youtube player in my application and I want to remove youtube logo from the Player. How can i achieve this thing? My application is developed using AS3. Simply add ?modestbranding=1 to the end of your URL. See more here . modestbranding (supported players: AS3, HTML5) This parameter lets you use a YouTube player that does not show a YouTube logo. Set the parameter value to 1 to prevent the YouTube logo from displaying in the control bar. Note that a small YouTube text label will still display in the upper-right corner of a paused video when the user's mouse pointer

i want to make a real-time update for my flash application. Instead on making it refresh each 30secs, i would prefer the push technology. What is the best way to push data in Actionscript 3 ? There are two popular options for implementing real-time updates: sockets and RTMP. There are advantages and disadvantages to each, but the primary deciding factor is usually your server infrastructure. Sockets Sockets provide the lowest-level functionality. This means you will need to implement a protocol in code on the client and on the server. However, the biggest advantage of this approach is that the

I'm a bit naive when it comes to bitwise logic and I have what is probably a simple question... basically if I have this (is ActionScript but can apply in many languages): var color:uint = myObject.color; var red:uint = color >>> 16; var green:uint = color >>> 8 & 0xFF; var blue:uint = color & 0xFF; I was wondering what exactly the `& 0xFF' is doing to green and blue. I understand what an AND operation does, but why is it needed (or a good idea) here? The source for this code was here: http://alexgblog.com/?p=680 Appreciate the tips. Alex In RGB you have 8 bits for Red, 8 bits for Green and 8

I have a utility function that will display a filesize in an appropriate form like Windows Explorer does, i.e; convert it to nearest KB, MB, GB etc. I wanted to know if the code that i wrote is correct, and if it can be made simpler. The function that i wrote is as follows : public static function formatFileSize(bytes:int):String { if(bytes < 1024) return bytes + " bytes"; else { bytes /= 1024; if(bytes < 1024) return bytes + " Kb"; else { bytes /= 1024; if(bytes < 1024) return bytes + " Mb"; else { bytes /= 1024; if(bytes < 1024) return bytes + " Gb"; } } } return String(bytes); } While it
