Detailed Description

Interface for a processing listener.


Member Function Documentation

void didProcess ( byte[]  imageBuffer,
int  width,
int  height,
ScanditSDKScanSession  session 

Invoked every time a frame has been processed by the recognition engine.

In contrast to ScanditSDKOnScanListener::didScan, the didProcess callback is invoked after every frame, regardless whether a code could be successfully decoded or not. If your are only interested in fully decoded codes, use the ScanditSDKOnScanListener instead.

The didProcess callback is invoked in the thread that runs the recognition engine and blocks further processing.

imageBufferthe raw image data that was processed in NV21 format
widthwidth of the image buffer in pixels
heightheight of the image buffer in pixels
sessioncontains information on the current recognition process. It is only valid to access the scan session from within the callback. If part of the information is required outside the callback it must be copied first.
