<param name="SCALE" value="showall" />
scale
Defines how the browser fills the screen with the SWF file. The default value is typically showall. Valid values of the scale property are showall, noborder, and exactfit.
Set to showall to make the entire SWF file visible in the specified area without distortion, while maintaining the original aspect ratio of the SWF file. Borders may appear on two sides of the SWF file.
Set to noborder to scale the SWF file to fill the specified area, without distortion but possibly with some cropping, while maintaining the original aspect ratio of the SWF file.
Set to exactfit to make the entire SWF file visible in the specified area without trying to preserve the original aspect ratio. Distortion may occur.
