AUIDocumentSize

The size of captured document in millimeters. You can define the size of the document to be captured so that the capturing mechanism will search the exact document on frames of the video stream. In case document size is unknown the mechanism will search for any document.

typedef CGSize AUIDocumentSize NS_TYPED_EXTENSIBLE_ENUM;{
   extern AUIDocumentSize const AUIDocumentSizeAny;
   extern AUIDocumentSize const AUIDocumentSizeA4;
   extern AUIDocumentSize const AUIDocumentSizeBusinessCard;
   extern AUIDocumentSize const AUIDocumentSizeLetter;
   extern AUIDocumentSize const AUIDocumentSizeID1;
   extern AUIDocumentSize const AUIDocumentSizeID2;
   extern AUIDocumentSize const AUIDocumentSizeID3;
};
