Public Methods

Method	Description
CleanupKerning ( Bytemap sourceFrame, bool number ) : List
CopyRectangle ( Bytemap source, Rectangle area ) : Bytemap	Copy a portion of an existing Bytemap into a new Bytemap. The rectangles that describe the position of the source and the selected area are all relative to the original page bitmap that the OCR is processing.
GetLetterImage ( Bitmap baseBmp, Rectangle frame, Size dimension ) : byte[]
GetPrimitiveLetters ( Bitmap bmp, Rectangle line ) : List
GetPrimitiveLines ( Bitmap bmp ) : List
IsNewHeadlineWord ( List letters, int i ) : bool
IsNewWord ( List letters, int i, bool small ) : bool

Private Methods

Method	Description
CopyLetter ( Bytemap source, Rectangle area, Size size ) : Bytemap	Copy a portion of an existing Bytemap into a new Bytemap. The new bytemap will always have a size of 'size' (typically a NN letter) regardless of the size of area. Pruning and zero-padding are used to ensure this. No data outside 'area' is copied. The rectangles that describe the position of the source and the selected area are all relative to the original page bitmap that the OCR is processing.
ExtractBytes ( Bitmap source ) : Bytemap
FloodFill ( int originalValue, byte targetValue, Size frame, byte letterBuf, bool number ) : void
FloodFillColumn ( int originalValue, byte targetValue, int a, Size frame, byte letterBuf, bool number ) : bool
GetRowHistogram ( Bitmap bmp, int y, int height ) : int[]
GetSubRect ( Rectangle r, byte letterBuf, int value ) : Rectangle
ImproveDescriptionLines ( Bitmap bmp, TextSection description ) : TextSection
RefinePartition ( ExplOCR.PageSections pageSections, Bitmap binary ) : ExplOCR.PageSections
