UI Customization
Is the UI of the Dynamic Web TWAIN SDK fully customizable? What cannot be customized?
Most UI is customizable: you can style or replace the viewer, thumbnail viewer, image editor, progress/loading indicators, and the install prompt (via dynamsoft.webtwain.install.js, e.g., Dynamsoft._show_install_dialog). You can also localize built-in error messages and other labels. What you cannot customize is the native scanner UI itself. See the full guide at UI Elements and customization.
