(was: Please edit your text so that the code is complete and also attach a PDF
file. Ideally, the code should have one line that sets the field with
something, so that when this line is removed the font is not embedded.)
> PDFBox Won't Embed a Font for a Form Field if Field is Empty
> ------------------------------------------------------------
>
> Key: PDFBOX-3832
> URL: https://issues.apache.org/jira/browse/PDFBOX-3832
> Project: PDFBox
> Issue Type: Bug
> Components: AcroForm, FontBox
> Affects Versions: 2.0.5, 2.0.6
> Reporter: Evan Williams
> Fix For: 2.0.7, 3.0.0
>
>
> When working with AcroForms, attempting to se the font of a form field, the
> font will only properly embed if the form field contains at least one
> character. Fonts set on empty fields do not embed. The font is only embedded
> if it is actually used.
> Example code:
> {code:Java}
> final PDFont formFont = loadFontResourceWithDef(pdf,
> DEFAULT_FONT_PATH,
> DEF_DOCUMENT_FONT);
> final PDResources resources = acroForm.getDefaultResources();
> final String fontName = resources.add(formFont).getName();
> acroForm.setDefaultResources(resources);
> this.defaultAppearanceString = "/" + fontName + " 0 Tf 0 g";
> }
> public static PDFont loadFontResourceWithDef(PDDocument doc,
> String fontpath, PDFont defFont) {
> PDType0Font resFont = null;
> try {
> final InputStream is =
> this.getClass().getResourceAsStream(fontpath);
> if (is != null) {
> resFont = PDType0Font.load(doc, is);
> }
> } catch (IOException e) {
> log("Error loading font " + fontpath, e);
> }
> return resFont != null ? resFont : defFont;
> }
> {code}
> Presume that I have verified that the font actually is loaded into the
> formFont variable.
> Some time later, I iterate over the fields in the acroform and, for each
> field, do this:
> {code:Java}
> if (field instanceof PDTextField) {
> final PDTextField textfield = (PDTextField) field;
> textfield.setDefaultAppearance(defaultAppearanceString);
> }
> {code}
