Constructor Detail

PDShadingType4

public PDShadingType4(COSDictionary shadingDictionary)

Constructor using the given shading dictionary.

Parameters:

shadingDictionary - The dictionary for this shading.

Method Detail

getShadingType

public int getShadingType()

This will return the shading type.

Specified by:

getShadingType in class PDShadingResources

Returns:

The shading type

setFunction

public void setFunction(PDFunction newFunction)

This will set the function for the color conversion.

Parameters:

newFunction - The new function.

getFunction

public PDFunction getFunction()
                       throws IOException

This will return the function used to convert the color values.

Returns:

The function
