为什么setFieldProperty返回false ?
本文关键字:false 返回 setFieldProperty 为什么 | 更新日期: 2023-09-27 18:08:58
我的代码将文本设置到字段中没有问题,但是当我试图更改字体时,它返回false。我尝试了一些其他字段属性,如文本大小,结果相同。我做错了什么?
public string Build()
{
Font font = FontFactory.GetFont(FontFactory.COURIER, 8f, Font.BOLD);
foreach (var i in this.pdfFields)
{
bool worked = this.acroFields.SetFieldProperty(i.Name, "textfont", font.BaseFont, null);
worked = this.acroFields.SetField(i.Name, i.Value);
}//foreach
this.pdfStamper.FormFlattening = false;
this.pdfStamper.Close();
return this.newFile;
}//Build

private string templateFile;
private string newFile;
private PdfReader pdfReader;
private PdfStamper pdfStamper;
private AcroFields acroFields;
private List<PDFField> pdfFields;
public PDFer(string templateFile, string newFile)
{
this.templateFile = templateFile;
this.newFile = newFile;
this.pdfReader = new PdfReader(this.templateFile);
this.pdfStamper = new PdfStamper(pdfReader, new FileStream(this.newFile, FileMode.Create));
this.acroFields = pdfStamper.AcroFields;
this.pdfFields = new List<PDFField>();
}//PDFer
public void AddTextField(string name, string value)
{
this.pdfFields.Add(new PDFTextField(name, value));
}//AddTextField
public void AddCheckBox(string name, bool isChecked)
{
this.pdfFields.Add(new PDFCheckBox(name, isChecked));
}//AddCheckBox
public float getWidth(string s)
{
Chunk c = new Chunk(s);
return c.GetWidthPoint();
}//getWidth
设置文本大小时,需要设置为Float
值。如果是int
,你用错了方法。当你设置字体时,你需要一个真正的BaseFont
对象。我认为你的font.BaseFont
是null
。我将像这样创建BaseFont:
BaseFont.CreateFont(BaseFont.COURIER, BaseFont.WINANSI, BaseFont.EMBEDDED);
注意,EMBEDDED将被忽略,因为COURIER是标准Type 1字体之一。
