Method Details

getDictString

public String getDictString()

Overrides:

getDictString in class WritableAnnotation

Returns:

Pdf specified dictionary string

getAPString

public String getAPString(int parentObj)

Description copied from class: WritableAnnotation

Overrides:

getAPString in class WritableAnnotation

Parameters:

parentObj - object number the appearance stream will be written as

Returns:

Pdf specified appearance stream object string, or null if there is none
