The technique of chroma key , ie the replacement of a certain color to another (or a different source), has exploded once again in the last decade with great arrogance, thanks to the increasingly widespread technology in the film and the processing of digital images.

Adobe Flash CS4: Create an Ajax Loader or Activity Indicator
Create an Ajax Loader (or Activity indicator for those who are already accustomed to using the Apple iPhone) for the Web is not a difficult thing: there are services that generate animated gif images of all types. However, the GIF format has the big drawback of not supporting transparent as it should. Transparency in GIF current plan involves only one bit with the consequence that if we do not have a background color uniform, the edges of the image are noticeably grainy and fragmented.

Actionscript 3.0 for beginners: lesson # 4
Recall the example of our code of TicTacToe (found in full on Google Code ) and begin to analyze it in detail.
Import definitions
With Actionscript 3.0 has done a great job of cleaning and accommodation nell'alberatura classes (contained in the packages, package ) used during development. In other programming languages, like C for example, when you want to use a feature must explicitly "import" in the code. This operation of "import" is necessary to allow the compiler to have all the codes and definitions related to the features we want to use. ; Actionscript 3.0 mette a disposizione l'istruzione include che è identica all' #include del C/C++. In ActionScript 3.0, however, education import should not be confused with the equivalent C / C + + #include , Actionscript 3.0 provides education include that is identical to ' #include in C / C + +. The latter, in fact, "include" the actual code that, if used or not, the final executable is compiled. The statement import is the highest level and is more "intelligent" at compile time. It is used primarily for access classes without specifying their full name. In alre words instead of using forms such as:

Very short trick: faster loops in Actionscript
In Actionscript cycles for it is good to use them with care. For example, you should use variables uint when you can:
You can also use the - not always known - the form:
Skypemote version of Adobe AIR
This is the first release, 0.8 (aligned with the version online ), Editor of Skype Emotions - Skypemote - version of Adobe AIR . For now, the features are all the same version online , with the advantage of being a desktop application, then install Windows, Mac and Linux.
Before installation, remember to update and / or install for the first time the runtime Adobe AIR , if you have not already done so.

Undolibrary MatrixArray: an extension of the Array class
di Actionscript 3.0, con lo scopo di semplificare la manipolazione di Array lineari usati come matrice n x m . MatrixArray is an extension of the class Array of Actionscript 3.0, with the aim to simplify the manipulation of Array used as a linear n x m matrix. This class is part of the library Undolibrary (in the package undolibrary.utils.MatrixArray ) that you can freely download function via any Google code SVN client (Subversion) to:
svn checkout http://undolibrary.googlecode.com/svn/trunk/
Alternatively you can download the single file MatrixArray.as . An example of the use of linear matrix was given in Actionscript 3.0 for beginners: lesson # 2 where we saw one of his simple use in the production of the classic Tic Tac Toe game. ), proprio come una scacchiera. An array of this type is comparable to a rectangular area ( w x h ), just like a chessboard. With this class you can treat an array of this type just like a grid with its x and y coordinates. The MatrixArray I've used, for example, in the development of all the logic editor Emotions Icons for Skype: Skypemote .
Skypemote.com: say it with emotions
Opens - in beta - Skypemote.com , a project born from an idea me and Nicola ( flussodigitale.com ), which proposes a simple editor to create nice drawings from "paste" in Skype. The editor has been created in Adobe Flash CS3 and, weather permitting, I would also release a version - Desktop - Adobe AIR.
If you use Skype to "chat" with this editor, you will surely impress your interlocutors. If you find this service useful and fun, do not forget to contribute suggestions, and - if you will - with some donations! 
Follow the project because there will soon be other "nice" news.
Actionscript 3.0 for beginners: lesson # 1
Premise
Actionscript 3.0 can be a good starting point to become familiar, those unfamiliar with C programming and / or C + +, orioentata programming (OOP). In addition, this series of lessons will be useful to those coming from other rooms or from earlier versions of Flash.
Set a project
In this first lesson we will see how to set up a project Flash CS3 generic. It is good to use when the projects are expected to have to deal with at least more than one file. The use of the project was introduced - by Macromedia - already in versions prior to CS3, so it should be a subject known to developers Actionscript 2.0.
However with Actionscript 3.0 - as we shall see - it is possible to create a Actionscript (. Pbuh) to the document-root movie ours. Fla so to speak. This feature is very useful and also makes a project minimum of at least two files: the. Fla. As associated. For this reason, you will "always" from a project, so right now organizing the various files (. Fla,. As, ...) that will be part of our "package" of development.
Also, once you learn the dimesticazza with the philosophy to objects, instrinseca in this type of language, end up with many files will be normal, even for simple projects substantially.
