THPDFBarcodeDecodeInfo Record
Status, DecoderName, and Diagnostic describe the overall outcome
RenderedPixels and PeakWorkingBytes expose raster resource use, whilst DecoderCallCount and RotationAttemptCount expose scan work
ReceivedResultCount, AcceptedResultCount, DroppedResultCount, and DuplicateResultCount explain validation and deduplication, with text and raw-byte totals measuring all decoder output inspected by HotPDF
ResultLimitReached reports successful truncation at MaxResults
