    Parameters:
    
    strokingAlphaConstant - a float value.
    
    Returns:
    
    object itself.
  - getFillOpacity
```
public Float getFillOpacity()
```
    Gets the current alpha constant, specifying the constant shape or constant opacity value for non-stroking operations in the transparent imaging model, ca key.
    
    Returns:
    
    a float value if exist, otherwise null.
  - setFillOpacity
```
public PdfExtGState setFillOpacity(float fillingAlphaConstant)
```
    Sets the current alpha constant, specifying the constant shape or constant opacity value for non-stroking operations in the transparent imaging model, ca key.
    
    Parameters:
    
    fillingAlphaConstant - a float value.
    
    Returns:
    
    object itself.
  - getAlphaSourceFlag
```
public Boolean getAlphaSourceFlag()
```
    Gets the alpha source flag (“alpha is shape”), specifying whether the current soft mask and alpha constant shall be interpreted as shape values (true) or opacity values (false), AIS key.
    
    Returns:
    
    a boolean value if exist, otherwise null.
  - setAlphaSourceFlag
```
public PdfExtGState setAlphaSourceFlag(boolean alphaSourceFlag)
```
    Sets the alpha source flag (“alpha is shape”), specifying whether the current soft mask and alpha constant shall be interpreted as shape values (true) or opacity values (false), AIS key.
    
    Parameters:
    
    alphaSourceFlag - if true - alpha as shape values, if false — as opacity values.
    
    Returns:
    
    object itself.
  - getTextKnockoutFlag
```
public Boolean getTextKnockoutFlag()
```
    Gets the text knockout flag, which determine the behaviour of overlapping glyphs within a text object in the transparent imaging model, TK key.
    
    Returns:
    
    a boolean value if exist, otherwise null.
  - setTextKnockoutFlag
```
public PdfExtGState setTextKnockoutFlag(boolean textKnockoutFlag)
```
    Sets the text knockout flag, which determine the behaviour of overlapping glyphs within a text object in the transparent imaging model, TK key.
    
    Parameters:
    
    textKnockoutFlag - true if enabled.
    
    Returns:
    
    object itself.
  - put
```
public PdfExtGState put(PdfName key,
                        PdfObject value)
```
    Puts the value into Graphics state parameter dictionary and associates it with the specified key. If the key is already present, it will override the old value with the specified one.
    
    Parameters:
    
    key - key to insert or to override
    
    value - the value to associate with the specified key
    
    Returns:
    
    object itself.
  - flush
```
public void flush()
```
    To manually flush a PdfObject behind this wrapper, you have to ensure that this object is added to the document, i.e. it has an indirect reference. Basically this means that before flushing you need to explicitly call PdfObjectWrapper.makeIndirect(PdfDocument). For example: wrapperInstance.makeIndirect(document).flush(); Note that not every wrapper require this, only those that have such warning in documentation.
    
    Overrides:
    
    flush in class PdfObjectWrapper<PdfDictionary>
  - isWrappedObjectMustBeIndirect
```
protected boolean isWrappedObjectMustBeIndirect()
```
    Defines if the object behind this wrapper must be an indirect object in the resultant document.
    
    If this method returns true it doesn't necessarily mean that object must be in the indirect state at any moment, but rather defines that when the object will be written to the document it will be transformed into indirect object if it's not indirect yet.
    
    Return value of this method shouldn't depend on any logic, it should return always true or false.
    
    Specified by:
    
    isWrappedObjectMustBeIndirect in class PdfObjectWrapper<PdfDictionary>
    
    Returns:
    
    true if in the resultant document the object behind the wrapper must be indirect, otherwise false.
