    Modifier and Type
    Method
    Description
    void
    fillAcroForm(File pdfFile, Map<String,String> fieldValues)
    Reads a pdf containing a AcroForm from the given input stream, sets all field values and returns the resulting PDF in the given OutputStream Fields are handled as follows: - if null is passed as value, the field is skipped - if the field is a PDCheckbox, the value is parsed as boolean, pass "true" to check it - if the field is a PDRadiobutton, the value is parsed as int (the index of the option to be selected) - else the string value is set as is
    void
    findAcroFieldnames(File pdfFile)
    This is a helper function that can be used to find the FullyQualified field names of an AcroForm - logs all fieldnames with some type information - prints the fieldname of all textfields into the field itself This method should probably not be used in production code, but it is very handy when implementing an automatic AcroForm field mapping
    void
    overlayImage(File pdfFile, String fieldname, byte[] image)
    Overlays an image over a PDF AcroForm Field The image is scaled as follows: - If the image is wider than the form field, the image is scaled down to the width of the field - If the shrinked image is higher than the form field, it is centered vertically over the form field and might overlap
    void
    removePage(File pdfFile, int pageNumber)
    Removes a page from a pdf document
