quantization | property |
public var quantization:uint| Language Version: | ActionScript 3.0 |
| Runtime Versions: | Flash Player 11.3, AIR 3.3 |
Specifies the amount of lossy in the compression. The range of values is 0 to 100, where a value of 0 means lossless compression. Larger values increase the lossy value and the resultant image becomes more grainy. A common value is 10. For values of 20 or larger, the image can become very grainy.
trimFlexBits | property |
public var trimFlexBits:uint| Language Version: | ActionScript 3.0 |
| Runtime Versions: | Flash Player 11.3, AIR 3.3 |
Determines the amount of extra entropy data that is cut after quantization. This property can affect image quality, and is typically left at the default value.
