| - | Note, this response can have up to three different feature sections, one for vectors (if vector(s) exist), one for intersections (if intersection(s) exist) and one for barcodes (if barcode(s) exist) in the image. Each feature section begins with a feature-type. The feature-length is next, which indicates how many bytes are in the feature-data. The feature-data is last, which has the data associated with the feature. Sometimes the feature-data section will have more than 1 of the given feature type, for example, if there is more than one barcode. | + | Note, this response can have up to three different feature sections, one for vectors (if vector(s) exist), one for intersections (if intersection(s) exist) and one for barcodes (if barcode(s) exist) in the image.
