Porting Existing Code

This chapter contains a detailed description about changes in the interface that have been made, that either might break existing code or lead to the deprecation of certain functions and structures and data types.

For each release version of the interface where changes that are important for development have been introduced this chapter will contain a section that will explain as detailed as necessary what these changes are and how to modify the code to run with the latest version of the interface.

Apart from that possible impacts on existing applications will be described as well.

Normally there won't be changes that require the developer to change his code. However when changes have been made it will only take a few minutes to port code to the latest version of the interface when sticking to this document.

Porting Existing Code Written With Versions Smaller Than 3.0.0

The release of 3.0.0 of the Impact Acquire interface does no longer contain interface members, that have been declared as deprecated in previous versions. The following list can be used to port code to this release. These changes will NOT affect existing binaries, thus application compiled with code from this list, will continue to work, but can't be built with a new interface release.

Changed Compile-time Behavior

List of classes, functions and data types that have been removed and their replacement:

• mvIMPACT.acquire.SettingsFrameGrabber
  This class was just a convenience collection of the classes mvIMPACT.acquire.CameraSettingsFrameGrabber, mvIMPACT.acquire.Connector, mvIMPACT.acquire.ImageDestination and mvIMPACT.acquire.ImageProcessing. Use these objects directly if needed!
