Camera1394 Features class.
Sets IIDC features from Config updates. Tracks values and ranges, modifying configured values to those supported by the device.

camera1394::Camera1394_* state values
Definition at line 70 of file features.h.
| Features::Features | ( | dc1394camera_t * | camera | ) |
Constructor
| camera | address of DC1394 camera structure. |

| Features::~Features | ( | ) | [inline] |

| void Features::configure | ( | dc1394feature_t | feature, |
| int * | control, | ||
| double * | value, | ||
| double * | value2 = NULL |
||
| ) | [private] |
Configure a feature for the currently open device.
| feature | desired feature number |
| control | [in,out] pointer to control parameter (may change) |
| value | [in,out] pointer to requested parameter value (may change depending on device restrictions) |
| value2 | [in,out] optional pointer to second parameter value for white balance (may change depending on device restrictions). No second value if NULL pointer. |
The parameter values are represented as double despite the fact that most features on most cameras only allow unsigned 12-bit values. The exception is the rare feature that supports "absolute" values in 32-bit IEEE float format. Double can represent all possible option values accurately.
Definition at line 262 of file features.cpp.
| Features::state_t Features::getState | ( | dc1394feature_info_t * | finfo | ) | [private] |
Get current state of a feature from the camera.
| finfo | pointer to information for this feature |
Definition at line 402 of file features.cpp.
| void Features::getValues | ( | dc1394feature_info_t * | finfo, |
| double * | value, | ||
| double * | value2 | ||
| ) | [private] |
Get feature values.
| finfo | pointer to information for this feature |
| value | [out] pointer where parameter value stored |
| value2 | [out] optional pointer for second parameter value for white balance. Otherwise NULL. |
Definition at line 463 of file features.cpp.
| bool Features::hasMode | ( | dc1394feature_info_t * | finfo, |
| dc1394feature_mode_t | mode | ||
| ) | [inline, private] |
Does this camera feature support a given mode?
| finfo | pointer to information for this feature |
| mode | DC1394 mode desired |
Definition at line 86 of file features.h.
| bool Features::initialize | ( | Config * | newconfig | ) |
Query and set all features for newly opened (or reopened) device.
| newconfig | [in,out] configuration parameters, updated to conform with device restrictions. |
Definition at line 137 of file features.cpp.
| void Features::reconfigure | ( | Config * | newconfig | ) |
Reconfigure features for already open device.
For each supported feature that has changed, update the device.
| newconfig | [in,out] configuration parameters, may be updated to conform with device restrictions. |
Definition at line 191 of file features.cpp.
| bool Features::setMode | ( | dc1394feature_info_t * | finfo, |
| dc1394feature_mode_t | mode | ||
| ) | [private] |
Set mode for a feature.
| finfo | pointer to information for this feature |
| mode | DC1394 mode desired |
Definition at line 553 of file features.cpp.
| void Features::setPower | ( | dc1394feature_info_t * | finfo, |
| dc1394switch_t | on_off | ||
| ) | [private] |
Set power for a feature On or Off.
| finfo | pointer to information for this feature |
| on_off | either DC1394_ON or DC1394_OFF |
Definition at line 588 of file features.cpp.
| void Features::updateIfChanged | ( | dc1394feature_t | feature, |
| int | old_control, | ||
| int * | control, | ||
| double | old_value, | ||
| double * | value | ||
| ) | [private] |
Update a feature for the currently open device, if changed.
Normal version: for features with one value parameter.
| feature | desired feature number |
| old_control | previous control parameter setting |
| control | [in,out] pointer to control parameter (may change) |
| old_value | previous parameter value |
| value | [in,out] pointer to requested parameter value (may change depending on device restrictions) |
Definition at line 624 of file features.cpp.

| int | old_control, | ||
| int * | control, | ||
| double | old_value, | ||
| double * | value, | ||
| double | old_value2, | ||
| double * | value2 | ||
| ) | [private] |
Update a feature for the currently open device, if changed.
Special version: for White Balance feature with two value parameters.
| feature | desired feature number |
| old_control | previous control parameter setting |
| control | [in,out] pointer to control parameter (may change) |
| old_value | previous parameter value |
| value | [in,out] pointer to requested parameter value (may change depending on device restrictions) |
| old_value2 | previous second parameter value |
| value2 | [in,out] pointer to requested second parameter value (may change depending on device restrictions). |
