maximumNumberOfConcurrentlyTrackableTargets
An integer value denoting how many concurrent targets are to be recognized and tracked simultaneously.
@property (nonatomic, assign) int maximumNumberOfConcurrentlyTrackableTargetsDiscussion
Depending on the current device, more targets can be recognized and tracked simultaneously. In case the maximum number of simultaneously targets is known for a specific use case, it’s good advice to set this property. The Wikitude Native SDK will stop searching for new image targets in case the limit is reached which results in better battery lifetime
Declared In
WTImageTrackerConfiguration.h
extendedTargets
An array of NSString objects that represent which targets of the .wtc file should be treated as extended targets.
@property (nonatomic, strong) NSArray *extendedTargetsDiscussion
The extended targets array is usually set through the client tracker creation factory method.
Declared In
WTImageTrackerConfiguration.h
physicalTargetImageHeights
Use this property to specify the physical height of individual image targets that are included in the .wtc file.
Physical target image heights are necessary as soon as any distance related API is used from the WTImageTarget
@property (nonatomic, strong) NSDictionary<NSString*NSNumber*> *physicalTargetImageHeightsDiscussion
This property is helpful if the physical image target height definition is missing in the .wtc file or if the values should be overriden with the given ones.
Declared In
WTImageTrackerConfiguration.h
trackerEfficiencyMode
Use this property to specify the efficiency mode of the tracker.
Please refer to the TrackerEfficiencyMode documentation for more details.

WTImageTrackerConfiguration.h
imageRecognitionRangeExtension
Defines the image recognition range extension that should be used when target image recognition is active.
@property (nonatomic, assign) WTImageRecognitionRangeExtension imageRecognitionRangeExtensionDiscussion
Warning: Setting this property to WTImageRecognitionRangeExtension_On on 32 bit devices will work but slows down computer vision algorithms performance noticable
@default WTImageRecognitionRangeExtension_Auto
Declared In
WTImageTrackerConfiguration.h
distanceChangedThreshold
Use this property to limit the number of distance changed callbacks comming from the WTImageTargetDelegate.
The value is interpreted as distance in millimeter.
@property (nonatomic, assign) unsigned int distanceChangedThresholdDiscussion
In order to receive accurate distance values, please provide physical target height information in the .wtc file or through the physicalTargetImageHeights property
