Embedding Movies with Flash, Part I: Basic Methods

Zooming In and Out a Flash Movie

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 cannot specify a reduction in the size of the objects in the view when the current view is already 100%.

Use the Flash method SetZoomRect() to zoom in on a specified area of the movie. The syntax is:

SetZoomRect(top, left, right, bottom)

This method zooms in on a rectangular area of the movie, starting at the top left corner and ending at the right bottom corner. All sizes are in twips (1440 units per inch), and there are 20 points to a twip.

Use the following links to play, rewind, zoom in, zoom out, zoom to a specific rectangle, and reset the view size to 100%:

Rewind | Play | Zoom In by 2x | Zoom Out by 2x | Zoom to Area | 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.
  SetZoomRect(0, 400, 1480, 1240); return false">
  Zoom to Area</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;
