iText7変更フォームのテキストの色

Question

私はiText7とJavaを使用してPDFフォームにデータを入力します。 pdfモジュールはAdobeプログラムで作成され、私はカスタムフォントを使用して、完成したPDFに埋め込みます。 色付きのテキストをpdfに追加しようとすると、プログラム全体がクラッシュします。どのようにできるのか ？ここで

は私がテキストを色付けするために使用するコードです：

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); 

そして、ここではそれがスロー例外です：

また、私はこれを試してみましたが、結果は同じです。

PdfTextFormField tf = (PdfTextFormField) fields.get("numeroRiga_l"); 
tf.setValue("#", boldFont, boldFontSize); 
tf.setColor(Color.WHITE); 

Answer 1

検索した後、私が最初に設定し、フォントを設定した後、色を正しく見つけました。フォントサイズを変更します。 つまり、同じ方法ではなく、順番に変換を行う必要があります。

の代わりに：

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

私が入力する必要があります。

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