Question

我的项目要求在PDF中绘制4个可编辑的textFields（签名），以便客户端可以在任一textFields中输入文本，并且该文本应该在表单上可见。

这里的问题是textFields是不透明的，顶部的textField隐藏了在它们之前绘制的所有textFields的文本。

任何解决方案或解决方法都会非常有用。

下面提到的是代码：

    private void AddTextFieldsToPDF()
    {
        {
            // The yOffset will move the text boxes above the signature line instead of somewhat on it.
    //OwnerSignYPosition : Float containing y-axis position of textField
    //Stacking one text field over other
            AddTextField(_reportDocument.DocWriter, "Field1", "field1", true, 40, OwnerSignYPos, 380, 18);
            AddTextField(_reportDocument.DocWriter, "Field2", "field2", true, 40, OwnerSignYPos, 380, 18);
            AddTextField(_reportDocument.DocWriter, "Field3", "field3", true, 40, OwnerSignYPos, 380, 18);
            AddTextField(_reportDocument.DocWriter, "Field4", "field4", true, 40, OwnerSignYPos, 380, 18);
        }
    }

protected void AddTextField(iTextSharp.text.pdf.PdfWriter writer, String fieldId, String fieldText, Boolean isSignature, float xPosition, float yPosition, float width, float height)
    {
        Rectangle position = new Rectangle(xPosition, yPosition, xPosition + width, Math.Max(yPosition - height, 0));
        iTextSharp.text.pdf.TextField field = new iTextSharp.text.pdf.TextField(writer, position, text);

        field.Text = fieldText;

        field.Box.BackgroundColor = Color.BLACK;
        field.Font = FontFactory.GetFont("Arial Narrow").BaseFont;
        field.TextColor = Color.WHITE; //new Color(0, 0, 255); // White
        field.FontSize = 9;
        writer.AddAnnotation(field.GetTextField());
    }

由于

在iTextSharp中的ITextFields中创建过多的文本字段
