Hi,
this is the code:
public static void main(String[] args) {
try {
PdfReader Read_PDF_To_Watermark = new
PdfReader("C:/SampleA.pdf");
int number_of_pages =
Read_PDF_To_Watermark.getNumberOfPages();
PdfAStamper stamp = new PdfAStamper(Read_PDF_To_Watermark,
new
FileOutputStream("C:/SampleAWM.pdf"),PdfAConformanceLevel.PDF_A_1A);
int i = 0;
Image watermark_image =
Image.getInstance("C:/watermark.png");
watermark_image.setAbsolutePosition(200, 400);
PdfContentByte add_watermark;
while (i < number_of_pages) {
i++;
add_watermark = stamp.getUnderContent(i);
add_watermark.addImage(watermark_image);
}
Read_PDF_To_Watermark.close();
stamp.close();
}
catch (Exception i1) {
i1.printStackTrace();
}
}
I have attached the PDF/A and the watermark:
SampleA.pdf
<http://itext-general.2136553.n4.nabble.com/file/n4659796/SampleA.pdf>
watermark.PNG
<http://itext-general.2136553.n4.nabble.com/file/n4659796/watermark.PNG>
when run this code
stamp.close();
there is this Exception:
