다음 코드 스니펫은 Aspose.PDF.Drawing 라이브러리와 함께 작동합니다.
Document 클래스는 PDF 문서에서 양식 필드를 관리하는 데 도움이 되는 Form이라는 컬렉션을 제공합니다.
양식 필드를 추가하려면:
아래 예제는 TextBoxField를 추가하는 방법을 보여줍니다.
// For complete examples and data files, visit https://github.com/aspose-pdf/Aspose.PDF-for-.NET
private static void AddTextBoxFieldToPdf()
{
// The path to the documents directory
var dataDir = RunExamples.GetDataDir_AsposePdf_Forms();
// Open PDF document
using (var document = new Aspose.Pdf.Document(dataDir + "TextField.pdf"))
{
// Create a field
var textBoxField = new Aspose.Pdf.Forms.TextBoxField(document.Pages[1], new Aspose.Pdf.Rectangle(100, 200, 300, 300));
textBoxField.PartialName = "textbox1";
textBoxField.Value = "Text Box";
// Configure border
var border = new Aspose.Pdf.Annotations.Border(textBoxField);
border.Width = 5;
border.Dash = new Aspose.Pdf.Annotations.Dash(1, 1);
textBoxField.Border = border;
// Set color
textBoxField.Color = Aspose.Pdf.Color.FromRgb(System.Drawing.Color.Green);
// Add field to the document
document.Form.Add(textBoxField, 1);
// Save PDF document
document.Save(dataDir + "TextBox_out.pdf");
}
}
다음 코드 스니펫은 PDF 문서에 RadioButtonField를 추가하는 방법을 보여줍니다.
// For complete examples and data files, visit https://github.com/aspose-pdf/Aspose.PDF-for-.NET
private static void AddRadioButtonToPdf()
{
// The path to the documents directory
var dataDir = RunExamples.GetDataDir_AsposePdf_Forms();
// Create PDF document
using (var document = new Aspose.Pdf.Document())
{
// Add a page to PDF file
document.Pages.Add();
// Instantiate RadioButtonField object with page number as argument
var radio = new Aspose.Pdf.Forms.RadioButtonField(document.Pages[1]);
// Add first radio button option and also specify its origin using Rectangle object
radio.AddOption("Test", new Aspose.Pdf.Rectangle(0, 0, 20, 20));
// Add second radio button option
radio.AddOption("Test1", new Aspose.Pdf.Rectangle(20, 20, 40, 40));
// Add radio button to form object of Document object
document.Form.Add(radio);
// Save PDF document
document.Save(dataDir + "RadioButton_out.pdf");
}
}
TextBoxField는 일부 위젯 주석과 함께 추가할 수 있습니다.
// For complete examples and data files, please visit https://github.com/aspose-pdf/Aspose.PDF-for-.NET
private static void AddTextBoxFieldToPdf()
{
// The path to the documents directory
string dataDir = RunExamples.GetDataDir_AsposePdf_Forms();
// Create PDF document
using (var document = new Aspose.Pdf.Document())
{
// Add a new page in the created document
var page = document.Pages.Add();
// Defining an array with rectangle data for widget annotations.
// The number of elements in the array determines the number of widget annotations to add.
var rects = new Rectangle[]
{
new Rectangle(10, 600, 110, 620),
new Rectangle(10, 630, 110, 650),
new Rectangle(10, 660, 110, 680)
};
// Defining an array with DefaultAppearance used to specify how widget annotations are displayed in the added field.
var defaultAppearances = new DefaultAppearance[]
{
new DefaultAppearance("Arial", 10, System.Drawing.Color.DarkBlue),
new DefaultAppearance("Helvetica", 12, System.Drawing.Color.DarkGreen),
new DefaultAppearance(FontRepository.FindFont("TimesNewRoman"), 14, System.Drawing.Color.DarkMagenta)
};
// Create a field
var textBoxField = new TextBoxField(page, rects);
// Setting the appearances of widget annotations
short i = 0;
foreach (WidgetAnnotation wa in textBoxField)
{
wa.DefaultAppearance = defaultAppearances[i++];
}
textBoxField.Value = "Text";
// Add field to the document
document.Form.Add(textBoxField);
// Save PDF document
document.Save(dataDir + "TextBox_out.pdf");
}
}
다음 코드 스니펫은 세 가지 옵션이 있는 RadioButtonField를 추가하고 이를 테이블 셀 안에 배치하는 단계를 보여줍니다.
// For complete examples and data files, visit https://github.com/aspose-pdf/Aspose.PDF-for-.NET
private static void AddRadioButtonWithOptionsToPdf()
{
// The path to the documents directory
var dataDir = RunExamples.GetDataDir_AsposePdf_Forms();
// Create PDF document
using (var document = new Aspose.Pdf.Document())
{
// Add a page to PDF file
var page = document.Pages.Add();
// Create a table
var table = new Aspose.Pdf.Table();
table.ColumnWidths = "120 120 120";
page.Paragraphs.Add(table);
// Add a row to the table
var r1 = table.Rows.Add();
// Add cells to the row
var c1 = r1.Cells.Add();
var c2 = r1.Cells.Add();
var c3 = r1.Cells.Add();
// Create a RadioButtonField
var rf = new Aspose.Pdf.Forms.RadioButtonField(page);
rf.PartialName = "radio";
document.Form.Add(rf, 1);
// Create RadioButtonOptionField options
var opt1 = new Aspose.Pdf.Forms.RadioButtonOptionField();
var opt2 = new Aspose.Pdf.Forms.RadioButtonOptionField();
var opt3 = new Aspose.Pdf.Forms.RadioButtonOptionField();
opt1.OptionName = "Item1";
opt2.OptionName = "Item2";
opt3.OptionName = "Item3";
opt1.Width = 15;
opt1.Height = 15;
opt2.Width = 15;
opt2.Height = 15;
opt3.Width = 15;
opt3.Height = 15;
rf.Add(opt1);
rf.Add(opt2);
rf.Add(opt3);
// Configure borders and captions for options
opt1.Border = new Aspose.Pdf.Annotations.Border(opt1);
opt1.Border.Width = 1;
opt1.Border.Style = Aspose.Pdf.Annotations.BorderStyle.Solid;
opt1.Characteristics.Border = System.Drawing.Color.Black;
opt1.DefaultAppearance.TextColor = System.Drawing.Color.Red;
opt1.Caption = new Aspose.Pdf.Text.TextFragment("Item1");
opt2.Border = new Aspose.Pdf.Annotations.Border(opt2);
opt2.Border.Width = 1;
opt2.Border.Style = Aspose.Pdf.Annotations.BorderStyle.Solid;
opt2.Characteristics.Border = System.Drawing.Color.Black;
opt2.DefaultAppearance.TextColor = System.Drawing.Color.Red;
opt2.Caption = new Aspose.Pdf.Text.TextFragment("Item2");
opt3.Border = new Aspose.Pdf.Annotations.Border(opt3);
opt3.Border.Width = 1;
opt3.Border.Style = Aspose.Pdf.Annotations.BorderStyle.Solid;
opt3.Characteristics.Border = System.Drawing.Color.Black;
opt3.DefaultAppearance.TextColor = System.Drawing.Color.Red;
opt3.Caption = new Aspose.Pdf.Text.TextFragment("Item3");
// Add options to the cells
c1.Paragraphs.Add(opt1);
c2.Paragraphs.Add(opt2);
c3.Paragraphs.Add(opt3);
// Save PDF document
document.Save(dataDir + "RadioButtonWithOptions_out.pdf");
}
}
다음 코드 스니펫은 RadioButtonField와 연결될 캡션을 추가하는 방법을 보여줍니다:
// For complete examples and data files, visit https://github.com/aspose-pdf/Aspose.PDF-for-.NET
private static void AddingCaptionToRadioButtonField()
{
// The path to the documents directory
var dataDir = RunExamples.GetDataDir_AsposePdf_Forms();
// Load source PDF form
using (var form1 = new Aspose.Pdf.Facades.Form(dataDir + "RadioButtonField.pdf"))
{
using (var document = new Aspose.Pdf.Document(dataDir + "RadioButtonField.pdf"))
{
foreach (var item in form1.FieldNames)
{
Console.WriteLine(item.ToString());
var radioOptions = form1.GetButtonOptionValues(item);
if (item.Contains("radio1"))
{
var field0 = document.Form[item] as Aspose.Pdf.Forms.RadioButtonField;
var fieldoption = new Aspose.Pdf.Forms.RadioButtonOptionField();
fieldoption.OptionName = "Yes";
fieldoption.PartialName = "Yesname";
var updatedFragment = new Aspose.Pdf.Text.TextFragment("test123");
updatedFragment.TextState.Font = Aspose.Pdf.Text.FontRepository.FindFont("Arial");
updatedFragment.TextState.FontSize = 10;
updatedFragment.TextState.LineSpacing = 6.32f;
// Create TextParagraph object
var par = new Aspose.Pdf.Text.TextParagraph();
// Set paragraph position
par.Position = new Aspose.Pdf.Text.Position(field0.Rect.LLX, field0.Rect.LLY + updatedFragment.TextState.FontSize);
// Specify word wraping mode
par.FormattingOptions.WrapMode = Aspose.Pdf.Text.TextFormattingOptions.WordWrapMode.ByWords;
// Add new TextFragment to paragraph
par.AppendLine(updatedFragment);
// Add the TextParagraph using TextBuilder
var textBuilder = new Aspose.Pdf.Text.TextBuilder(document.Pages[1]);
textBuilder.AppendParagraph(par);
field0.DeleteOption("item1");
}
}
// Save PDF document
document.Save(dataDir + "RadioButtonField_out.pdf");
}
}
}
다음 코드 스니펫은 PDF 문서에 ComboBox 필드를 추가하는 방법을 보여줍니다.
// For complete examples and data files, visit https://github.com/aspose-pdf/Aspose.PDF-for-.NET
private static void AddComboBoxToPdf()
{
// The path to the documents directory
var dataDir = RunExamples.GetDataDir_AsposePdf_Forms();
// Create PDF document
using (var document = new Aspose.Pdf.Document())
{
// Add page to document object
document.Pages.Add();
// Instantiate ComboBox Field object
var combo = new Aspose.Pdf.Forms.ComboBoxField(document.Pages[1], new Aspose.Pdf.Rectangle(100, 600, 150, 616));
// Add options to ComboBox
combo.AddOption("Red");
combo.AddOption("Yellow");
combo.AddOption("Green");
combo.AddOption("Blue");
// Add combo box object to form fields collection of document object
document.Form.Add(combo);
// Save PDF document
document.Save(dataDir + "ComboBox_out.pdf");
}
}
Document 클래스는 PDF 문서에서 양식 필드를 관리하는 Form이라는 컬렉션을 제공합니다. 양식 필드에 툴팁을 추가하려면 Field 클래스의 AlternateName을 사용합니다. Adobe Acrobat은 ‘대체 이름’을 필드 툴팁으로 사용합니다.
다음 코드 스니펫은 C#을 사용하여 양식 필드에 툴팁을 추가하는 방법을 보여주고, 그 다음 Visual Basic을 사용합니다.
// For complete examples and data files, visit https://github.com/aspose-pdf/Aspose.PDF-for-.NET
private static void AddTooltipToField()
{
// The path to the documents directory
var dataDir = RunExamples.GetDataDir_AsposePdf_Forms();
// Open PDF document
using (var document = new Aspose.Pdf.Document(dataDir + "AddTooltipToField.pdf"))
{
// Set the tooltip for textfield
if (document.Form["textbox1"] is Aspose.Pdf.Forms.Field field)
{
field.AlternateName = "Text box tool tip";
}
// Save PDF document
document.Save(dataDir + "AddTooltipToField_out.pdf");
}
}
