Programming notes

Hinweis

Apart from camera-specific functions, the uEye SDK is almost identical with the SDK for the FALCON and EAGLE frame grabbers from IDS. The Notes on FALCON functions chapter includes a list of functions from the FALCON SDK which are not supported by the uEye camera.

Notes on parameter validity

Functions that refer to an initialized camera have the camera handle HIDS hCam as the first parameter. All parameters that are set using these functions remain valid for as long as the handle is valid, that is, until you close the corresponding camera or exit the program. The next time you open the camera, it is initialized with the defaults again.

Achtung

All input parameters of a function have to be initialized with valid values before the function is called; this also applies to parameters that are not used. Variables can be preset with '0', for example. For unused parameters, the NULL pointer has to be passed.

The uEye.h header file

The uEye.h header file contains all the definitions and constants needed for the uEye API. After the installation of the uEye drivers you will find this file in the directory:

•Windows: C:\Program Files\IDS\uEye\Develop\include

•Linux: /usr/include
