Camera object member functions | |
These functions must be implemented by a camlib and the camlib's camera_init() function will add them to a Camera object. | |

Object representing a camera attached to the system. A Camera object represents a specific instance of a (physical of virtual) camera attached to the system. The abilities of this type of camera are stored in a CameraAbility object. The details of the Camera object are internal. |
|
For example, you would probably set the speed to the highest one right before downloading an image, and reset it to the default speed afterwards so that other programs will not be affected by this speed change. |
|
gp_camera_capture: : a Camera : a #CameraCaptureType : a #CameraFilePath : a #GPContext Captures an image, movie, or sound clip depending on the given . The resulting file will be stored on the camera. The location gets stored in . The file can then be downloaded using #gp_camera_file_get.
|
|
Close connection to camera.
It is recommended that you call this function when you currently don't need the camera. The camera will get reinitialized by gp_camera_init() automatically if you try to access the camera again. |
