Hi Joshua,
creating new fields is tricky. I searched a long time in Google and in the
mailing list and found only questions and no working answer. Then with a lot
help of the PDFDebugger and some source code reading I found a solution. This
ist of course not the best but for the moment it is working for me and I will
optimize it later.
One thing still not works: The font is not set. Don't know why.
Here is the code:
PDTextbox newField = new PDTextbox(acroForm);
PDFont font = PDType1Font.TIMES_ITALIC;
PDResources dr = new PDResources();
dr.addFont(font);
COSDictionary drDict;
drDict = dr.getCOSDictionary();
newField.getWidget().getDictionary().setItem(COSName.getPDFName("DR"),
drDict);
PDAppearance ap = new PDAppearance(acroForm, newField);
// the line above is the important part I think
PDRectangle rect = new PDRectangle();
rect.setLowerLeftX((float) 90.7);
rect.setLowerLeftY((float) 450.0);
rect.setUpperRightX((float) 250.0);
rect.setUpperRightY((float) 470.0);
newField.getWidget().setRectangle(rect);
newField.setPartialName("newField");
newField.setValue("New Field");
newField.getWidget().setPage(page);
newField.getDictionary().setName(COSName.TYPE, "Annot");
newField.getDictionary().setName(COSName.SUBTYPE, "Widget");
newField.getDictionary().setName(COSName.FT, "Tx");
// these three lines makes the field visible
acroForm.getFields().add(newField);
page.getAnnotations().add(newField.getWidget());
Hope, it will help you.
Best regards
Manfred
