iText7 ändern Formular Textfarbe

Question

Ich verwende iText7 und Java, um PDF-Formulare zu füllen. Die pdf-Module wurden mit Adobe-Programm erstellt und ich benutze eine benutzerdefinierte Schriftart, die ich in das fertige PDF einbette. Wenn ich versuche, der PDF-Datei einen farbigen Text hinzuzufügen, stürzt das gesamte Programm ab. Wie kann ich ?

Hier ist der Code, den ich den Text zu verwenden Farbe:

String fontPath = this.getClass().getResource("RobotoCondensed-Regular.ttf").getPath(); 
PdfAcroForm form = PdfAcroForm.getAcroForm(pdfDoc, false); 
Map<String, PdfFormField> fields = form.getFormFields(); 
PdfFont regularFont = PdfFontFactory.createFont(fontPath, true); 
fields.get("scadenza_r").setValue("Scadenza:", regularFont, regularFontSize).setColor(Color.BLUE); 

Und hier ist die Ausnahme wirft:

ich auch schon versucht, diese, aber das Ergebnis ist das gleiche:

Answer 1

Nach der Suche fand ich die Farbe applies richtig, wenn ich es zuerst und nach dem Festlegen der Schriftart, und a nach der Schriftgröße. Mit anderen Worten, ich muss die Transformationen der Reihe nach durchführen, und nicht innerhalb derselben Methode.

Statt:

fields.get("scadenza_r").setValue("Scadenza:", regularFont, regularFontSize).setColor(Color.BLUE); 

I eingeben müssen:

fields.get("scadenza_r").setValue("Scadenza:").setColor(Color.Blue).setFont(regularFont).setFontSize(regularFontSize);
