-----------------------------------------------------------------
I added this for the missing fonts, which is just a guess that it's the correct
font
{code:java}
PDAcroForm acroForm = doc.getDocumentCatalog().getAcroForm();
acroForm.setNeedAppearances(false);
PDFont font1 = PDType0Font.load(doc, new
FileInputStream("c:/windows/fonts/times.ttf"), false);
PDFont font2 = PDType0Font.load(doc, new
FileInputStream("c:/windows/fonts/timesbd.ttf"), false);
PDFont font3 = PDType0Font.load(doc, new
FileInputStream("c:/windows/fonts/arial.ttf"), false);
acroForm.getDefaultResources().put(COSName.getPDFName("TimesNewRomanPSMT"),
font1);
acroForm.getDefaultResources().put(COSName.getPDFName("TimesNewRomanPS-BoldMT"),
font2);
acroForm.getDefaultResources().put(COSName.getPDFName("Helvetica"), font3);
for (PDField field: acroForm.getFieldTree())
{
if (field instanceof PDTextField)
{
if (((PDTextField) field).isMultiline())
{
field.setValue("XXX");
}
}
}
{code}
But when setting a value, this happens in
AppearanceGeneratorHelper.setAppearanceContent():
{code}
if (bmcIndex == -1)
{
// append to existing stream
writer.writeTokens(tokens);
writer.writeTokens(COSName.TX, BMC);
}
{code}
So it appends to the existing appearance steam. This is the result after
calling setValue("XXX"):
{code}
