Hi,
flatten() will flatten the form fields but without refreshing the fields
appearance i.e. how you see it on the form. Now, as NeedAppearances is set to
true, the prior setValue() call also didn't refresh the fields appearance as
the NeedAppearances flag tells the viewer to handle that.
There are two options: set the NeedAppearances flag to false using
PDAcroForm.setNeedAppearances(false) or use flatten(List<PDField> fields,
boolean refreshAppearances).
Unfortunately there is an issue with the form as it doesn't contain a /DR entry
(i.e. it doesn't specify which resources, most important the fonts, to use).
Exception in thread "main" java.lang.IllegalArgumentException: /DR is a
required entry
PDFBox doesn't yet have a fall back see PDFBOX-2662.What you could do is
generate an appropriate entry yourself.
PDResources dr = new PDResources();
dr.put(COSName.getPDFName("Courier"), PDType1Font.COURIER);
dr.put(COSName.getPDFName("Helvetica"), PDType1Font.HELVETICA);
pdAcroForm.setDefaultResources(dr);
That reveals another issue
Exception in thread "main" java.lang.NullPointerException
at
org.apache.pdfbox.pdmodel.PDPageContentStream.<init>(PDPageContentStream.java:195)
Which is caused as the annotations are not connected to a page.
The can be resolved by
for (PDPage page : pdDoc.getPages()) {
for (PDAnnotation annot : page.getAnnotations()) {
annot.setPage(page);
}
}
Finally setReadOnly() needn't be set for the field as after flatten() there are
no more fields.
So the final code looks like that
try {
File myFile = new File(template);
PDDocument pdDoc = PDDocument.load( myFile );
PDDocumentCatalog pdCatalog =
pdDoc.getDocumentCatalog();
PDAcroForm pdAcroForm = pdCatalog.getAcroForm();
// set the NeedApperances flag
pdAcroForm.setNeedAppearances(false);
// correct the missing page link for the annotations
for (PDPage page : pdDoc.getPages()) {
for (PDAnnotation annot :
page.getAnnotations()) {
annot.setPage(page);
}
}
// Add the missing resources to the form
PDResources dr = new PDResources();
dr.put(COSName.getPDFName("Courier"),
PDType1Font.COURIER);
dr.put(COSName.getPDFName("Helvetica"),
PDType1Font.HELVETICA);
pdAcroForm.setDefaultResources(dr);
PDField field = pdAcroForm.getField("Make");
field.setValue("Jeep");
field = pdAcroForm.getField("Model");
field.setValue("Grand Cherokee");
field = pdAcroForm.getField("Check Box1");
field.setValue("Yes");
pdAcroForm.flatten();
pdDoc.save(flattened);
pdDoc.close();
}
catch (Exception e) {
e.printStackTrace();
}
