What is WILL™?
WILL™ (Wacom Ink Layer Language) is a specific standard for digital ink, which is created and stored in a special format because a digital pen creates more data than other input devices such as a mouse or keyboard, including pressure, tilt, and rotation.
Specially developed algorithms take the raw data created by digital pens, styluses or touch display, and vectorize it into a stunning visual representation of digital ink.
The .will file format is specifically designed to exchange digital ink content between devices and applications, and is implemented as an open and extensible binary format.

The WILL data specification has been designed conceptually to be suitable for multiple use cases, and to accommodate the specific characteristics of pen-generated digital ink.
WILL™ Features & capabilities
WILL™ 3.0 is even more beautiful
WILL™ technology has always powered visually authentic and aesthetically pleasing digital ink. WILL™ 3.0 moves the game on with an optimized format and a new rendering engine that replicates hand-drawn pen strokes more accurately than ever.
It's the key to enabling developers to create beautiful inking apps.
The WILL™ 3.0 framework consists of three core inking elements that enable the accurate, attractive and flexible rendering of digital ink:
Ink rendering: Allows the generation of a visually smooth ink by leveraging the sensor data created by digital pen strokes
Ink serialization: Enables the storage of ink data with the universal ink data format that can be combined with other data types
Ink manipulation: The manipulation module provides a set of algorithms that can be used as building blocks to implement functions such as:
WILL™ 3.0 uses a geometry pipeline that processes the pointer data created by the digital pen or other digital ink input device in relation to these three elements.
Each stage of the pipeline process has its own purpose in terms of creating a customizable visual image of digital ink produced by the device. These purposes include smoothing and spline interpolation, among others.
The process also enables a choice of ink rendering techniques - raster/particle or vector rendering.
WILL™ is biometrically accurate
WILL™ 3.0 enables the capture of sensor data that is biometrically accurate and which can be directly connected to a specific time and place. That means, for example, it is possible to identify when and where an electronic document was signed, by whom and using which device.
The WILL™ 3.0 universal ink model captures all the relevant sensor data from the digital ink-enabled device when an electronic signature is provided. This data includes:
Combined with the capture of other contextual data such as the device manufacturer, serial number, OS, author, timestamp and other metadata, a complete, biometrically accurate record of a signature can be created.
This creates an intuitive and natural-feeling signing experience for the user. Moreover, the data can also be used together with Wacom's enhanced signature verification technology to help verify the authenticity of a signature, should it be questioned.
In addition, handwriting comparisons captured using the biometric data captured within WILL™ 3.0 universal ink could help reveal the emotional state of the user via signs of stress in the words being created. These signs could include, for example, harder pressure being applied with the pen on the screen than is usual, or more erratic handwriting. This capability opens up a variety of new use cases in the education, healthcare and financial sectors in terms of fraud detection.
WILL™ powers seamless collaboration
WILL™ 3.0 SDKs give you everything you need to develop high-value digital ink applications for a wide range of pen-enabled devices.
Using your existing infrastructure, you can continuously add features with minimum development time and low Total Cost of Ownership (TCO).
WILL™ 3.0 SDKs feature high-performance writing and sketching tools. Their frameworks enable the biometrically accurate capture and conversion of digital ink data,as well as a range of data exchange and collaboration options.
Fast, realistic and attractive digital ink rendering creates a very natural writing feel, and a direct, authentic response on screen.
Visually aesthetic and customizable natural stroke dynamics further enhance the user experience. Your advantages as a developer include
Broad compatibility for maximum freedom
Next to voice control, handwriting is a very natural way for humans to visualize, document and communicate ideas. That's why the desire to digitize handwriting is driving a boom in pen-enabled devices, and increasing demand for applications that can utilize this technology in new and interesting ways.
The WILL™ 3.0 inking framework is compatible with Windows, Android, iOS and also offers web SDKs, making collaborations with ink between different platforms and technologies easy.
This means that WILL™ 3.0 allows users to exchange digital ink creations between a wide range of devices. This is important given that 88% of users leverage more than one device when working on a project. WILL™ 3.0-powered digital ink also remains editable and can be used in different WILL™ 3.0-compatible apps, software and services.
So, whether your customers use Wacom devices, the Apple Pencil, or Samsung S Pen, you can use the WILL™ 3.0 platform to build applications for them.
WILL™ 3.0 SDKs empower you to build unique, innovative digital ink apps using your existing infrastructure and continuously create new features with minimum development time and low Total Cost of Ownership (TCO). Your advantages include:
This maximizes your business opportunity by enabling you to build apps for the broadest possible range of potential customers.
