dwt 16.0.0

v16.0

on Node.js NPM

Added a new mobile edition that enables document capturing via mobile cameras and other document manipulation functionalities. Most of the existing methods and properties are made compliant with this new edition.

Added WASM based document manipulation functionalities which enable the use of all features of Dynamic Web TWAIN except for document scanning without installing the Dynamsoft Service.

Added setting Dynamsoft.WebTwainEnv.UseLocalService to switch the working mode of the library between Local-Service mode and WASM mode. Only valid on desktop operating systems.

Replaced the built-in image viewer including the built-in image editor with the Dynamsoft Viewer.

The creation of a WebTwain instance is now independent from the UI. In version 16.0, you can create a WebTwain instance in 4 ways

• Specify a Container that has a ContainerId and assign it to Dynamsoft.WebTwainEnv.Containers. A ContainerId is essentially the id of an HTMLDivElement element which is required for generating a built-in Dynamsoft Viewer. Then call the method Dynamsoft.WebTwainEnv.GetWebTwain with ContainerId as the argument to get the instance.
• Call the method Dynamsoft.WebTwainEnv.CreateDWTObject to create an instance with built-in Dynamsoft Viewer.
• Specify a Container that has a WebTwainId but no ContainerId and assign it to Dynamsoft.WebTwainEnv.Containers. A WebTwainId is just a string to uniquely specify the instance. Then call the new method Dynamsoft.WebTwainEnv.GetWebTwainEx with WebTwainId as the argument to get the instance.
• Call the method Dynamsoft.WebTwainEnv.CreateDWTObjectEx to create an instance without a built-in Dynamsoft Viewer.

Added method LoadImageFromBinary() to enable importing data from binary (an object of the type Blob or ArrayBuffer).

Added methods getCapabilities() and setCapabilities() which enables fast capability negotiation.

Added method EnableSourceUI() to enable TWAIN configuration without scanning.

Added method SelectImages() to select one or multiple images programmatically. This method replaces the old APIs SetSelectedImageIndex() and SelectedImagesCount.

Added property SelectedImagesIndices to return the indices of selected images. This property replaces the old API GetSelectedImageIndex().

Added Viewer-specific APIs: setViewMode(), updateUISettings(), setButtonClass(), setSelectedImageArea(), zoomIn(), zoomOut(), bindCustomElement(), showCustomElement(), hideCustomElement(), toggleCustomElement(). These methods should be called like this: DWObject.Viewer.zoomIn().
