STU

Differences between STU and Signature SDKs

The main differences between the two SDKs are as follows:

Simplifies signature capture with a range of Wacom tablets including STU and DTU
Signature data is saved in an undisclosed proprietary format and can be used with other Wacom signature products such as Signature Scope and Signature Verification
Signature image creation available in the SDK
User Interface and signature data format is defined by the SDK
It is not possible to use more than one tablet with the Signature SDK as it has no mechanism for selecting the device
Signatures are rendered using Wacom Ink Layer Language (WILL) for a high quality digital pen and ink experience

Used for signature capture with the range of STU tablets only
Developer is free to save the signature data in any format but this will not be compatible with the undisclosed Signature SDK data
User Interface and signature data format are open to the developer
Signature image must be created by the developer from the pen data values
