Class ScanDirectionType

Inheritance
System.Object
ScanDirectionType
Namespace: DynamicTesseract
Assembly: IronOcr.dll
Syntax
public sealed class ScanDirectionType : Enum

ScanDirectionType controls which way a low-level Leptonica scan traverses pixels while analyzing an image during preprocessing. The axis values, ScanHorizontal and ScanVertical, set the direction a run is read, with ScanBoth covering both axes. The edge values, FromLeft, FromRight, FromTop, and FromBottom, fix where a traversal starts, while ScanPositive and ScanNegative set the sweep sign. Most projects never set this directly, since IronOCR's higher-level reading and filter steps select a sensible direction on their own.
