Method Details

isLateExternalSigning

public boolean isLateExternalSigning()

setLateExternalSigning

public void setLateExternalSigning(boolean lateExternalSigning)

Set late external signing. Enable this if you want to activate the demo code where the signature is kept and added in an extra step without using PDFBox methods. This is disabled by default.

Parameters:

lateExternalSigning - external signing flag

setVisibleSignDesigner

public void setVisibleSignDesigner(String filename,
 int x,
 int y,
 int zoomPercent,
 FileInputStream imageStream,
 int page)
