Add signature initials

It’s possible to implement signature initials within the signature modal using workarounds. This guide walks you through two possibilities.

Workaround 1

• You can use an event to detect when the modal is opened and closed, and based on the logic, you can set and reset the labels.
• The add signature string has an I18n entry with the key addSignature.
• Here’s a snippet to change the addSignature label:

instance.addEventListener("viewState.change", (viewState) => {
      if (viewState.interactionMode === PSPDFKit.InteractionMode.SIGNATURE) {
        PSPDFKit.I18n.messages["en-GB"].addSignature = "Add Initials";
      }
    });

Workaround 2

• There’s a Catalog example(opens in a new tab) that achieves something similar using custom renderers. Refer to the custom renderers guide for more information.
