using Aspose.Pdf.Plugins;

string inputPath = @"C:\Samples\sample.pdf";
string outputPath = @"C:\Samples\sample_with_fields.pdf";

var plugin = new FormEditor();
var addOptions = new FormEditorAddOptions(
    new[] {
        // Textbox
        new FormTextBoxFieldCreateOptions(1, new Rectangle(10, 700, 90, 715)) {
            MaxLen = 20,
            Value = "Name",
            Color = Color.Brown
        },
        // Checkbox
        new FormCheckBoxFieldCreateOptions(1, new Rectangle(110, 700, 125, 715)) {
            Value = "Agree",
            PartialName = "CheckBox_Agree",
            Color = Color.Blue
        },
        // Combobox
        new FormComboBoxFieldCreateOptions(1, new Rectangle(310, 600, 350, 615)) {
            Color = Color.Red,
            Editable = true,
            DefaultAppearance = new DefaultAppearance("Arial Bold", 12, System.Drawing.Color.DarkGreen),
            Options = new[] {"Option1", "Option2", "Option3"},
            Selected = 1
        }
    });
addOptions.AddInput(new FileDataSource(inputPath));
addOptions.AddOutput(new FileDataSource(outputPath));
plugin.Process(addOptions);

var removeOptions = new FormEditorRemoveOptions(
    new[] { "CheckBox_Agree", "TextBoxField1" } // Field names to remove
);
removeOptions.AddInput(new FileDataSource(outputPath));
removeOptions.AddOutput(new FileDataSource(@"C:\Samples\sample_fields_removed.pdf"));
plugin.Process(removeOptions);
