SetBitmapBits Method of the TrainingImage Object
Important! This method is not implemented.
This method sets the training image data from the buffer in memory.
The image should be isotropic (that is its horizontal resolution should be equal to the vertical one), black-and-white with 1 bit per pixel encoding.
Image is stored in buffer continuously, line-by-line, from top to bottom. One line of black-and-white image is stored as a sequence of at least N = ceil ( width / 8 ) bytes. Each byte encodes colors of 8 adjacent pixels, most significant bit of the first byte corresponds to leftmost pixel of the line. Bit value of 0 denotes white pixel, value of 1 denotes black pixel. If width is not a multiple of 8, least significant bits of N-th byte are ignored.
Syntax
HRESULT SetBitmapBits( int Height, int Width, __int64 RawDataPointer );
Parameters
- Height
- [in] Specifies the height of the training image in pixels.
- Width
- [in] Specifies the width of the training image in pixels.
- RawDataPointer
- [in] This parameter is treated as a handle to memory buffer containing image data. The handle is passed as __int64.
Return values
This method returns E_NOTIMPL. See details in the standard return values of ABBYY FineReader Engine functions.
Remarks
The image data should exist while the corresponding TrainingImage object exists.
