Apache PdfBox how to set field font size
问题
我正在使用org.apache.pdfbox读取PDF并填充一些字段。
现在我有一个问题，那就是字体大小太大了。
我以为将字体大小设置为12会很容易。但事实证明它非常复杂。
实际上这很糟糕。有人知道如何做吗？以下是我的无样式代码：
final PDDocument document = PDDocument.load(template);PDPage page = new PDPage(PDRectangle.A4);document.addPage(page);final PDAcroForm acroForm = document.getDocumentCatalog().getAcroForm();final Iterator<PDField> it = acroForm.getFieldIterator();for (PDField f : acroForm.getFields()) {System.out.println(f.toString());if (f instanceof PDTextField) {f.set // 此处省略了一些代码f.setValue("Some value");}};
英文:
I am using org.apache.pdfbox to read pdf and outfill some fields.
Now I have to problem that the font size is much too big.
I thought it would be easy to set font size to 12 . But it is very complicated .
Actually it is awful. Does anyone know how to do it ? This is my code without styling.
final PDDocument document = PDDocument.load(template);PDPage page = new PDPage(PDRectangle.A4);document.addPage(page);final PDAcroForm acroForm = document.getDocumentCatalog().getAcroForm();final Iterator<PDField> it = acroForm.getFieldIterator();for (PDField f : acroForm.getFields()) {System.out.println(f.toString());if (f instanceof PDTextField) {f.setf.setValue("Some value");}};

根据评论讨论，以下是结果：
((PDTextField) f).getDefaultAppearance()
是
/Helv 0 Tf 0 g
这表示Helvetica字体，大小为0（可变大小），颜色为黑色（灰色色彩空间，0为黑色，1为白色）。
因此，要设置特定大小，请调用
((PDTextField) f).setDefaultAppearance("/Helv 12 Tf 0 g")
英文:
As discussed in the comments, the result of
((PDTextField) f).getDefaultAppearance()
is
/Helv 0 Tf 0 g
which means Helvetica, size 0 (= variable size), and color black (grey colorspace, 0 is black, 1 is white).
Thus to set a specific size, call
((PDTextField) f).setDefaultAppearance("/Helv 12 Tf 0 g")
