Form Elements

HyperlinkElement

HyperlinkElement renders clickable text with a link annotation in the PDF. It works just like TextElement visually, but tapping or clicking the text opens the URL.

c.add(new HyperlinkElement("https://example.com", "Visit our website")
    .fontSize(11)
    .color(Colors.BLUE_600)
);

The first argument is the URL and the second is the visible link text. Any URI scheme works, including https://, mailto:, and internal PDF destinations.

Common methods:

Method	What it does
`.fontSize(float)`	Sets the font size in points
`.color(KawaColor)`	Sets the link text color
`.font(KawaFont)`	Applies a custom font

InputElement

InputElement creates a fillable text field. PDF viewers that support forms let users type into it.

c.add(new InputElement("firstName")
    .label("First Name")
    .height(22)
);

The constructor argument is the field's internal name, which form-processing tools use to identify and extract the value.

Multiline fields

c.add(new InputElement("message")
    .label("Message")
    .multiline(80)    // height of the textarea in points
);

Styling

// Underline style instead of a box border
new InputElement("signature").label("Signature").underline()

// Custom border color
new InputElement("quantity").borderColor(Colors.BLUE_400)

// Custom background color
new InputElement("notes").backgroundColor(Colors.YELLOW_50).multiline(55)

// Pre-filled value
new InputElement("phone").label("Phone").value("+49 ")

Common methods

Method	What it does
`.label(String)`	Sets the label text above the field
`.labelFontSize(float)`	Sets the label font size
`.height(float)`	Sets the field height
`.multiline(float)`	Turns the field into a multiline textarea with the given height
`.value(String)`	Sets a pre-filled default value
`.underline()`	Renders the field as an underline instead of a box
`.borderColor(KawaColor)`	Sets the border color
`.backgroundColor(KawaColor)`	Sets the background fill color
