Description

Results array for Landmark (iegrLandmarkDetection request), Logo (iegrLogoDetection request), Label (iegrLabelDetection request) and Text detection (iegrTextDetection request).

  

  

Example

Cursor := crHourglass;
lblSubmitting.Visible := True;
GVision := TIEGoogleVision.Create( MY_API_KEY );
try
  // Use recommended delivery size (for faster processing)

  GVision.RequestTypes := [iegrWebDetection, iegrSafeSearchDetection, iegrLandmarkDetection];
  GVision.ProcessImage( edtFilename.Text );

  lbxResults.Clear();

  if Length( GVision.WebDetection.bestGuessLabels ) > 0 then
