OpenBitmapBits Method of the Engine Object

Important! This method is not implemented.

This method opens the specified bitmap data and supports the following image formats:

  • 1-bit monochrome (each pixel is represented as 1 bit).
  • 8-bit gray (each pixel is represented as 8 bits).
  • 24-bit color (each 24 bits use 8 bits of each R, G, B component).

Syntax

HRESULT OpenBitmapBits(
  BitmapBitsFormatEnum Format,
  int                  Width,
  int                  Height,
  int                  ByteWidth,
  int                  XResolution,
  int                  YResolution,
  __int64              RawDataPtr,
  IPrepareImageMode*   PrepareMode,
  IImageDocument**     Result
);
    

Parameters

Format
[in] This parameter of the BitmapBitsFormatEnum type describes the format of the bitmap data to be opened.
Width
[in] Specifies the width of the bitmap in pixels. This parameter must not be 0.
Height
[in] Specifies the height of the bitmap in pixels. This parameter must not be 0.
ByteWidth
[in] Specifies the width of the line of bitmap in bytes (padding included). This parameter must not be 0.
XResolution
[in] Specifies the horizontal resolution of the bitmap in dots per inch.
YResolution
[in] Specifies the vertical resolution of the bitmap in dots per inch.
RawDataPtr
[in] This parameter is treated as a handle to memory buffer containing bitmap data.  The handle is passed as __int64. See the description of the BitmapBitsFormatEnum constants for details on the data format.
PrepareMode
[in] Refers to the PrepareImageMode object that defines the mode of image preparation. It may be 0, in which case default values for the PrepareImageMode properties will be used, or, if a profile has been loaded, the parameters set by this profile are used.
Result
[out, retval] A pointer to IImageDocument* pointer variable that receives the interface pointer of the resulting ImageDocument object.

Return values

This method returns E_NOTIMPL. See details in the standard return values of ABBYY FineReader Engine functions.

Remarks

This method does not work if the Engine is loaded as an out-of-process server.
