Parameters

Parameter	Description
size	The signature field's size in twips.
pageNumber	Specifies the number of a page beginning with 1 where the signature field is located.

Examples

The following example demonstrates SignatureFieldCollection.addAtFixedPositionOnPage in a practical document-editing workflow. It inserts a new image which has a fixed geometrical position in the document. This position is specified through a page number and a location on this page.

function onTxError(error) {
    console.error("TX Text Control error:", error.msg);
    error.handled = true;
}

TXTextControl.signatureFields.addAtFixedPositionOnPage(
    { width: 2880, height: 1440 },
    1,
    { x: 1440, y: 720 },
    TXTextControl.FrameInsertionMode.AsCharacter,
    function(signatureField) {
        if (!signatureField) {
            console.warn("No signature field was returned.");
            return;
        }
        
        console.log("add at fixed position on page result:", signatureField);
    },
    onTxError
);
