Member Enumeration Documentation
| anonymous enum |
The list of builtin event types.
Builtin FCam events use positive integers. They are guaranteed not to have collisions and should all be listed here. Custom events should use negative integers, and may collide with other custom events (so you should check the creator and the type).
- Enumerator:
Error An error occurred.
Warning A warning occurred.
FocusPressed The focus button was pressed (typically the shutter button was half-depressed).
FocusReleased The focus button was released.
ShutterPressed The shutter button was pressed.
ShutterReleased The shutter button was released.
N900LensClosed The lens cover on the N900 was closed.
N900LensOpened The lens cover on the N900 was opened.
N900SlideOpened The keyboard on the N900 was slid open.
N900SlideClosed The keyboard on the N900 was slid closed.
F2LensRemoved The lens on the F2 was removed.
F2LensInstalled A new lens was inserted in the F2.
F2ZoomChanged The lens on the F2 was manually zoomed.
F2FocusChanged The lens on the F2 was manually focused.

The list of builtin error and warning codes.
Builtin FCam warning and error codes use positive integers. Custom events should use negative integers.
- Enumerator:
Unknown Should not be used.
Indicates the error event is uninitialized.
InternalError Indicates a probable bug inside FCam.
Inform the developers.
DriverError Something unexpected happened while communicating with the FCam drivers.
ImageTargetLocked FCam was requested to place image data in an image that was locked.
ResolutionMismatch FCam was requested to place image data in a target of the wrong size.
OutOfMemory A memory allocation failed inside FCam.
FrameLimitHit Too many frames are waiting on the frame queue.
Call getFrame more frequently.
LensHistoryError The state of the lens was requested for a time too far in the past or the future.
FlashHistoryError The state of the flash was requested for a time too far in the past or the future.
DemosaicError Could not demosaic this image.
ImageLockError Incorrect usage of Image::lock or Image::unlock.
BadCast A TagValue was cast to a mismatched type.
FileLoadError A file could not be read in succesfully.
FileLoadWarning A file isn't quite as expected.
FileSaveError A file couldn't be written.
FileSaveWarning A file couldn't be saved quite as expected.
SensorStoppedError getFrame called before calling capture or stream
ParseError Could not read a TagValue from a string.
FrameDataError Expected frame data (tags, image data) was not available.
OutOfRange An argument was outside the valid or accurate range of inputs.
