Using Macromedia Flash 8 (bundled in Studio 8) in Windows XP.

Macromedia Flash, or simply Flash, refers to both a multimedia authoring program and the Macromedia Flash Player, written and distributed by Macromedia (recently targeted for acquisition by Adobe Systems), that utilizes vector and raster graphics, a native scripting language called ActionScript and bidirectional streaming of video and audio. Strictly speaking, Macromedia Flash is the authoring environment and Flash Player is the virtual machine application used to run the Flash files, but in colloquial language these have become mixed: "Flash" can mean either the authoring environment, the player or the application files.

The Flash files (or "Movies"), which usually have an SWF file extension, may appear in a web page for viewing in a web browser, or for "playing" in the standalone Flash Player. Flash files occur most often as animations, advertisements or design elements on web pages and, more recently, Rich Internet Applications. A Flash file can contain more diverse information than a GIF or JPEG file of the same size.

Programming Language

Pre-2.0 ActionScript may be used alone or together with ActionScript 2.0 to access to the same objects and resources within Flash MX 2004. While ActionScript 2.0 offers a few object-oriented features, such as events, interfaces, and inheritance, most of Flash MX 2004's object-oriented capability lies solely within its compiler.

ActionScript 2.0 may be compiled with the built-in compiler in the Flash IDE or with Motion Twin ActionScript2 Compiler (MTASC). See external links.

Security

Flash Player uses a sandbox security model, which means that Flash applications running in a browser have very strict and limited resources available to them. The applications cannot, for example, read files from the hard disk (except the cookie-like data they themselves have written). They can only communicate with the domain they originated from, unless explicitly allowed by another domain.

Flash Player is, as any application that handles files received from the Internet, susceptible to attacks. Specially crafted files could potentially cause the application to malfunction, by allowing execution of malevolent code. The Player plug-in has had security flaws which may expose a computer to remote attacks. See 1 and 2 for a December 2002 problem, addressed by a public warning and patch from Macromedia. Fortunately, all the security incidents have been only proof-of-concept breaches and never escalated into real-world problems.

Flash can retain information locally (in a manner similar, but more extensive, to browser cookies), giving the client the ability to, for example, remember the level or score a user has achieved on a Flash-based game, or the settings used on a previously visited website. This can compromise the security of users' data and privacy, and there are already reports of existing exploitation by advertisers (for example, Persistent Information Element). Most users, including those familiar with Flash who protect themselves from cookies, are unaware of this kind of tracking, which is not curtailed by customary in-browser cookie settings and most cookie-cleaning utilities. The persistent data can be avoided by applying settings described at Macromedia's web site 3. The default storage location of these files (for Windows XP) is in the Macromedia\Flash Player\#SharedObjects of the Application Data directory for each user. These data can only be accessed by Flash Movies from the same domain.

Not all browsers have a direct way for saving .swf files, and many times the context menu of most browsers won't work on Flash objects. However, some browsers like Mozilla Firefox can save .swf files to disk just by performing a "Complete Web page" saving, and searching the associated "w/._files" directory for .swf files. Another way, using Adblock, is to click on the Adblock tab, copy and paste the URL of the .swf file into another window, and then "Save Page As", allowing the user to download only the .swf anywhere he chooses. This doesn't work with Internet Explorer and perhaps other browsers. With Internet Explorer one can try however to search for .swf files in the "Temporary Internet Files" directories.

The files can also be downloaded by using web grabber software such as Wget. Once the .swf file is saved locally, the Flash application files can quite easily be decompiled into its source code and assets. Several available programs extract graphics, sounds and program code from swf files. For example, an open source program called Flasm allows users to extract ActionScript from a swf file as virtual machine intermediate language ("byte-code"), it, and then reinsert it into the file. Obfuscation of the swf files makes the extraction infeasible in most cases.

Competition

Format and plug-in

Compared to other plugins such as Java, QuickTime or Windows Media Player, the Flash Player has very small install size and fast initialization time.

Like CSS with HTML, PostScript, SVG and PDF, Flash can be used to specify exact positioning of the various page elements. This gives the designer a great degree of control over how the user interface looks. The layout can also be adjusted programmatically at run-time.

The use of vector graphics (like PostScript, SVG and PDF)—especially when combined with program code—allows Flash files to translate to small file sizes which take less bandwidth to transmit than bitmaps or video clips do. In many cases, Flash is a very attractive solution for delivering mixed content. If the content is purely one format (such as text, video or audio), other alternatives may provide better outcome. Also, depending on the type of application or animation created (in particular, transparency or large screen updates as in photographic or text fades) a Flash movie may need more CPU power than alternatives.

Flash as a format has become very widespread on the desktop market. Through an NPD study, Macromedia claims that 98% of Web users have Flash Player installed 4—90% having the latest version. Numbers vary depending on the detection scheme and research demographics: Webhits (German page) counts only 69% of Flash-enabled browsers.

Macromedia has released the specifications of the Flash file format (excluding specifications of related formats such as AMF), and compatible third-party tools exist. However, Macromedia retains control of the format. Since Flash files do not depend on a truly open standard such as SVG, this reduces the incentive for non-commercial software to support the format, although there are several third party tools which utilize and generate the SWF file format and a large and vibrant open source community. Apparently, the Flash Player cannot ship as part of a pure open source, or completely free operating system, as its distribution is bound to the Macromedia Licensing Program and subject to approval.

Authoring

In October 1998 Macromedia disclosed the Flash Version 3 Specification to the world on its website. It did this in response to many new and often semi-open formats competing with SWF, such as XARA's Flare and Sharp's Extended Vector Animation formats. Several developers quickly created a C library for producing SWF. February 1999 saw the launch of MorphInk 99, the first non-Macromedia or third party program to create SWF files. Macromedia also hired Middlesoft to create a freely-available developers' kit for the SWF file format versions 3 to 5. Many open and free libraries based on the information released to the public in 1998, and from later study of the SWF file format, such as the Ming library, exist to produce SWF files on many platforms. Macromedia has made the Flash Files specifications for versions 6 and later available only as a PDF under a non-disclosure agreement.

Many shareware developers produced Flash creation tools and sold them for under $50 USD between 2000 and 2002. In 2003 competition and the emergence of free Flash creation tools, most notably OpenOffice.org, had driven many third-party Flash-creation tool-makers out of the market, allowing the remaining developers to raise their prices, although many of the products still cost less than $100 USD and support Actionscript. As for open source tools, F4L has started to develop a SWF authoring tool including an interface similar to that of Macromedia's. KTOON can vectors and generate SWF, but its interface is very different from Macromedia's.

Adobe wrote a software package called Adobe LiveMotion, designed to create interactive animation content and export it to a variety of formats, including SWF. LiveMotion went through two major releases, but failed to gain any notable user base. Adobe cancelled it in 2003.

In February 2003, Macromedia purchased Presidia, which had developed a Flash authoring tool that automatically converted PowerPoint Files into Flash. Macromedia subsequently released the new product as Breeze, which included many new enhancements. Since that time, Macromedia has seen competing PowerPoint to Flash authoring tools from Articulate, PointeCast (not to be confused with PointCast), and PresentationPro.

In November 2003 Microsoft announced that it had started working on a competing product, Sparkle, whose release would coincide with that of their next-generation Windows operating system, Windows Vista. The purchase of Creature House Inc.'s assets in September 2003 has led to speculation that their Expression graphics engine would form the basis for the Sparkle product.

Influence

Probably due to wide usage of Flash in web advertisements, tools have emerged for blocking Flash content in some or all web sites, or temporarily or permanently turning Flash Player off. For example, FlashBlock and Adblock for the Mozilla Firefox browser.

Macintosh performance

Macromedia has been criticized for neglecting to optimize its products on the Mac OS X platform. This has led to poor web surfing performance on Macintosh computers, since many websites use Flash animations for menus and advertisements. 5 6

Macromedia does however claim that Flash Player 8, will "bring performance very close to its Windows counterpart". 7

Product history

Future developments

Attendees at selected Macromedia seminars and conferences in 2004 previewed some future features of the Flash player (version 8). The most notable new features included realtime video alpha channels, a new advanced font-rendering engine, and improved Flash player detection and bitmap effects (blurs, drop shadows). Video alpha channels allow Flash to display video clips with transparency. The example SWF shown used a video clip of a person walking across the screen while the background video clip could be changed by clicking separate buttons. The clip of the person blended seamlessly into whichever background was selected.

Flash guru Colin Moock has written about some of the new features and provides video clips from Macromedia's presentation in Tokyo.
