| PDStreamFunction | | protected PDStreamFunction(PDDocument doc, int functionType)(Code) | | Constructor to create a new blank function, should only be called by
subclasses.
Parameters:
doc - The document that this function is part of.
Parameters:
functionType - An integer describing the function type, only 0,2,3,4are defined by the PDF sepc. |
| PDStreamFunction | | public PDStreamFunction(PDStream functionDictionary)(Code) | | Constructor.
Parameters:
functionDictionary - The prepopulated function dictionary. |
| getCOSObject | | public COSBase getCOSObject()(Code) | | Convert this standard java object to a COS object.
The cos object that matches this Java object. |
| getCOSStream | | public COSStream getCOSStream()(Code) | | This will get the underlying array value.
The cos object that this object wraps. |
| getDomainForInput | | public PDRange getDomainForInput(int n)(Code) | | This will get the range for a certain input parameter. This is will never
return null. If it is not present then the range 0 to 0 will
be returned.
Parameters:
n - The parameter number to get the domain for. The domain range for this component. |
| getNumberOfInputParameters | | public int getNumberOfInputParameters()(Code) | | This will get the number of input parameters that
have a domain specified.
The number of input parameters that have a domainspecified. |
| getNumberOfOutputParameters | | public int getNumberOfOutputParameters()(Code) | | This will get the number of output parameters that
have a range specified. A range for output parameters
is optional so this may return zero for a function
that does have output parameters, this will simply return the
number that have the rnage specified.
The number of input parameters that have a rangespecified. |
| getRangeForOutput | | public PDRange getRangeForOutput(int n)(Code) | | This will get the range for a certain output parameters. This is will never
return null. If it is not present then the range 0 to 0 will
be returned.
Parameters:
n - The output parameter number to get the range for. The range for this component. |
| setDomainForInput | | public void setDomainForInput(PDRange range, int n)(Code) | | This will set the domain for the input values.
Parameters:
range - The new range for the input.
Parameters:
n - The number of the input parameter to set the domain for. |
| setRangeForOutput | | public void setRangeForOutput(PDRange range, int n)(Code) | | This will set the a range for output parameter.
Parameters:
range - The new range for the output parameter.
Parameters:
n - The ouput parameter number to set the range for. |
