SymbolInstance object
Last updated 5/2/2011
Usage
symbolInstance.bitmapRenderMode
Description
Property; a string that sets the display type for the symbol.
Acceptable values include:
• “none”
• “cache” - sets the symbol to be cached as a bitmap by Flash Player at runtime.
• “export” - sets the symbol to be exported as a bitmap when the SWF is compiled.
The older “ symbolInstance.cacheAsBitmap ” on page 419 property is similar to this property, but it offers fewer
choices since it's a boolean. In the future, the cacheAsBitmap property may be deprecated, so users should switch to
this new property. The true/false options in the boolean
cacheAsBitmap property are the same as the "cache" / "none"
values for this new property.
Example
The following example assigns the symbol’s
bitmapRenderMode to “export”:
var symbol = fl.getDocumentDOM().selection[0];
fl.trace(symbol.bitmapRenderMode);
symbol.bitmapRenderMode = "export";
symbolInstance.blendMode
Availability
Flash 8.
Usage
symbolInstance.blendMode
Description
Property; a string that specifies the blending mode to be applied to a movie clip symbol. Acceptable values are
"normal" , "layer" , "multiply" , "screen" , "overlay" , "hardlight" , "lighten" , "darken" , "difference" ,
"add" , "subtract" , "invert" , "alpha" , and "erase".
Example
The following example sets the blending mode for the first movie clip symbol in the first frame on the first level to
add :
fl.getDocumentDOM().getTimeline().layers[0].frames[0].elements[0].blendMode = "add";
