In some of your applications you may need to use Flash movies and JavaScript directly, without any prepackaged APIs such as FlashSound JavaScript API. You will enjoy more features, methods, and properties, but you'll have to take care of all the tiny details that are taken for granted when using FlashSound API, for example.

One of the "tiny" details is embedding the Flash object. The JavaScript file flashmoviecheck.js does exactly this, as well as other stuff. For example, it checks whether a Flash player exists (Flash plug-in or ActiveX control), and whether its version is higher than the minimum required by the application.

Use the Flash method Zoom() to zoom in or out of a Flash movie. The syntax is:

  Zoom(percent)
This method zooms the view by a relative scale factor specified by percent. Zoom(50) doubles the size of the objects in the view. Zoom(200) scales down the size of the objects in the view by one half. Zoom(0) resets the view to 100%. You can not specify a reduction in the size of the objects in the view when the current view is already 100%.

Use the following links to play, rewind, zoom in, zoom out, and resets the view size to 100%:

Rewind | Play | Zoom In by 2x | Zoom Out by 2x | Reset Size

Here is the code:

<SCRIPT LANGUAGE="JavaScript" SRC="flashmoviecheck.js"></SCRIPT>
<A href="javascript://" onclick="javascript:mySwf.Rewind(); return false">Rewind</A> | 
<A href="javascript://" onclick="javascript:mySwf.Play(); return false">Play</A> |
<A href="javascript://" onclick="javascript:mySwf.Zoom(50); return false">Zoom In by 2x</A> | 
<A href="javascript://" onclick="javascript:mySwf.Zoom(200); return false">Zoom Out by 2x</A> | 
<A href="javascript://" onclick="javascript:mySwf.Zoom(0); return false">Reset Size</A>
<SCRIPT LANGUAGE="JavaScript">
  Flash_embedSWF("swift3d.swf");
  var mySwf = window.document.sonify;
</SCRIPT>
