Library version number
The library version has the following structure: <major>.<minor>.<patchlevel>.<buildnumber>
For example, the library version 1.2.8.0 produces a value of 1020800 after evaluation of the VIB_VERSION expression by the compiler.
| enum eFG_CAMERA_TYPE |
The following camera models are supported by this library.
| enum eFG_ERROR_CODE |
The result code for all library functions.
| Enumerator | |
|---|---|
| FG_ERROR_CODE_NoError | The function was successful. |
| FG_ERROR_CODE_Unknown | Unknown error. |
| FG_ERROR_CODE_InvalidArgument | The function arguments are invalid. |
| FG_ERROR_CODE_InvalidCameraChannel | The selected camera channel is invalid. |
| FG_ERROR_CODE_GrabTimeOut | Only valid for FG_get_image(): acquisition timeout. |
| FG_ERROR_CODE_BrokenImage | Only valid for FG_get_image(): the returned image contents are invalid. |
| FG_ERROR_CODE_ExtraErrorInformation | Other errors, use FG_get_last_error() to obtain the error message. |
| enum eFG_PIXEL_ORDER |
Order of pixel components in memory (see FG_get_pixel_order()).
| enum eFG_PIXEL_TYPE |
Specifies the format to use for captured images (see FG_get_aoi() / FG_set_aoi()).
Support for the different pixel types depend on the used sensor, see also:
| enum eFG_TRIGGER_MODE |
Trigger mode definitions, see FG_set_trigger_mode() for a description.
| Enumerator | |
|---|---|
| FG_TRIGGER_MODE_SOFTWARE | Software triggered mode. |
| FG_TRIGGER_MODE_HARDWARE | Hardware triggered mode. |
| FG_TRIGGER_MODE_FREERUN | Free-run triggered mode. |
