public enum PDFAutoOptimizerMode

public final class PDFAutoOptimizerMode 
    extends java.lang.Enum<PDFAutoOptimizerMode>

[SerializableAttribute()] 
public enum class PDFAutoOptimizerMode

class PDFAutoOptimizerMode(Enum): 
   Customized = 0 
   BestSize = 1 
   MediumSize = 2 
   AverageSize = 3 
   GoodQuality = 4 
   BestQuality = 5

Members

Value	Member	Description
0	Customized	Use custom settings.
1	BestSize	Optimize for smallest file size
2	MediumSize	Optimize favoring size over quality
3	AverageSize	Optimize with balance between size and quality
4	GoodQuality	Optimize favoring quality over size
5	BestQuality	Optimize for highest quality
