RTRImageCaptureStatus

The current status of the image capture, including current frame. Returned value is intended for the UI feedback.

Properties

Name Type Description
documentBoundary NSArray<NSValue*>*

The detected document boundary. Currently the result is always returned as the four vertex points of the bounding quadrangle. The vertices are indexed clockwise starting from the bottom left.

Get the NSValue.CGPointValue property to obtain point coordinates as a CGPoint.

imageSize CGSize Current image size represented by its width and height in pixels.
motionVector CGVector The vector that indicates the image position shifting in comparison to the previous state.
qualityAssessmentForOCRBlocks NSArray<RTRQualityAssessmentForOCRBlock*>* The quality assessment blocks.
relativeQuality NSInteger

The value from internal image quality scale. Larger value means better image quality. The minimum value is 0.

 Note: This API is available only in the extended version of the library. For correct quality comparison the image should represent the document at the same scene. If the background changes at some images, parameter values will not represent appropriate for comparison data.

sampleBuffer CMSampleBufferRef The processed frame.
