創(chuàng)建PDF表單域時(shí)，開發(fā)人員可以對(duì)表單域進(jìn)行修飾以獲得更好的視覺效果。Aspose.Pdf.Kit提供了FormFieldFacade類來(lái)實(shí)現(xiàn)這一功能。表單域可以被修飾的屬性包括：邊框樣式，寬度和顏色，背景色，字體，字體大小，標(biāo)題，文字顏色，文字對(duì)齊，文字旋轉(zhuǎn)。為了獲得更詳細(xì)的信息，參考 FormFieldFacade的成員。

　　為了使用FormFieldFacade類，開發(fā)人員應(yīng)按下面的步驟結(jié)合FormEditor類：

• 新建一個(gè)FormFieldFacade對(duì)象和一個(gè)FormEditor對(duì)象，指定FormEditor.Facade屬性值為新建的FormEditor對(duì)象。
• 使用FormFieldFacade類修飾PDF表單域的屬性。
• 在修飾完所有屬性后，調(diào)用FormEditor.ResetFacade方法將所有的可視屬性置為空值 。
• 使用FormEditor.Save方法保存所有修改。

示例代碼

[C#]

FormEditor formEditor = new FormEditor("student.pdf", "added.pdf");

//創(chuàng)建一個(gè)FormFieldFacade對(duì)象用于指定可視屬性
FormFieldFacade facade = new FormFieldFacade();

//為FormEditor對(duì)象的Facade屬性指定一個(gè)facade對(duì)象
formEditor.Facade = facade;

//添加一個(gè)帶有灰色背景以及下陷邊框的按鈕域
facade.BackgroudColor = System.Drawing.Color.FromArgb(0xCC, 0xCC, 0xCC);
facade.BorderStyle = FormFieldFacade.BDSTYLE_BEVELED;
 formEditor.AddField(Aspose.Pdf.Kit.FieldType.PushButton,

"button1", "OK", 1, 265, 695, 365, 720);

//清除設(shè)置

formEditor.ResetFacade();

//關(guān)閉并保存輸出文檔
formEditor.Save();

FormEditor formEditor2 = new FormEditor("added.pdf", "Result.pdf");

//指定按鈕提交時(shí)的目標(biāo)URL
formEditor2.SetSubmitUrl("button1","//www.ASPOSE.COM");
formEditor2.Save();
