property RequestTypes: TIEGRequestTypes;


Specify what Google Vision detection operations to call.

Value Google Feature Description
iegrWebDetection WEB_DETECTION Run web detection
iegrSafeSearchDetection SAFE_SEARCH_DETECTION Run Safe Search to detect potentially unsafe or undesirable content
iegrLabelDetection LABEL_DETECTION Run label detection
iegrObjectLocalization OBJECT_LOCALIZATION Run localizer for object detection
iegrFaceDetection FACE_DETECTION Run face detection
iegrLandmarkDetection LANDMARK_DETECTION Run landmark detection
iegrLogoDetection LOGO_DETECTION Run logo detection
iegrTextDetection TEXT_DETECTION Run text detection / optical character recognition (OCR). Text detection is optimized for areas of text within a larger image; if the image is a document, use iegrDocumentTextDetection instead
iegrDocumentTextDetection DOCUMENT_TEXT_DETECTION Run dense text document OCR. Takes precedence over iegrTextDetection
iegrCropHintsDetection CROP_HINTS Run crop hints
iegrProductSearch PRODUCT_SEARCH Run Product Search (Unhandled)
iegrImageProperties IMAGE_PROPERTIES Compute a set of image properties, such as the image's dominant colors

Note: After changing the RequestTypes you must call ProcessImage again to update your results.

Default: [iegrFaceDetection, iegrLandmarkDetection, iegrLogoDetection, iegrLabelDetection,
