The Future of Flash Macromedia has signed a memorandum of understanding with Adobe that will form the basis for the sale of Macromedia in fall of this year. There is no risk of the deal collapsing, and equally no danger of the Flash platform being discontinued. Flash is defi- nitely one major reason for Adobe’s interested in Macromedia. Version eight of the authoring environment and player are expected in the fall. Macromedia currently has the ambitious goal of establishing itself on the mobile device market. Agreements on the implementation of a Flash Lite player were signed with Sam- sung and Nokia this spring with an eye to promoting the propaga- tion of Flash technology.

In many Thankfully, KToon has useful tooltips to help you out. Version 0.7 gives you a choice of interface languages from Spanish, French, and English. If you feel up to adding a localized version, the developers will certainly appreciate your help. You’ll find a lan- guage template (file extension .ts) on the KToon website. The template is actually an XML file that you can edit yourself. Although you can’t actually integrate the localized file yourself, you can send it to the KToon development team, and chances are it will be in the next version. KToon has a fairly rudimentary feature set at present. For example, the tool’s ability to create complex vectors, one of Flash’s major strengths, is very limited. Also, KToon can export the Flash pro- gramming language Actionscript.

Decrypted, FAME refers to the fol- lowing components: Flashout + ASDT + MTASC + Eclipse. Most users have heard by now of Eclipse, an open development platform that is customizable using plug-ins. ADST is the Actionscript Development Tool for Eclipse. Actionscript, the pro- gramming language of the Macromedia Flash developer environment, is based on the ECMA 4 standard. MTASC is the abbreviation for Motion Twin Action- script 2 Compiler, the first open source compiler for Actionscript. MTASC offers benefits such as extremely quick com- pilation of Actionscript classes and direct generation of SWF files without requiring Macromedia Flash.
