Gottingen w ISIOSens 4 Software Development Kit 4 1 Philosophy Our philosophy is to enable you to realize your application with a minimum amount of development time To be also independent of operation system structure the SDK for VFU Series is based on the DotNet Framework for Windows machines and the equivalent Mono Framework for Linux This allows changing your application to a different operation system even when your application development is already done A major new feature is the so called Self Describing Interface This interface takes care of all camera specific parameters in a way that the Software Engineer don t have to take care about parameters such as e g available image sizes or gain settings All the specific info can be requested by an equivalent info method When using this interface the Software Engineer can easily exchange the camera hardware e g change to another image sensor without changing his implementation A complete implementation example is provided with the Demo Application Please feel free to reuse this source code but please notice that it is provided as is and visiosens cannot give any warranty of function for this A detailed description of all methods can be found in the XML Documentation installed together with the Software Development Kit 4 2 SDK Configuration The behavior of VFU dll can be configured using the DotNet Framework Each application can contain its own schematic XML code The
