OpenBitmapBits Method of the Engine Object
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
C++
HRESULT OpenBitmapBits( BitmapBitsFormatEnum Format, int Width, int Height, int ByteWidth, int XResolution, int YResolution, __int64 RawDataPtr, IPrepareImageMode* PrepareMode, IImageDocument** Result );
C#
IImageDocument OpenBitmapBits( BitmapBitsFormatEnum Format, int Width, int Height, int ByteWidth, int XResolution, int YResolution, Int64 RawDataPtr, IPrepareImageMode PrepareMode );
Visual Basic .NET
Function OpenBitmapBits( _ Format As BitmapBitsFormatEnum, _ Width As Integer, _ Height As Integer, _ ByteWidth As Integer, _ XResolution As Integer, _ YResolution As Integer, _ RawDataPtr As Int64, _ [PrepareMode As IPrepareImageMode = Nothing] _ ) As IImageDocument
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 has no specific return values. It returns the standard return values of ABBYY FineReader Engine functions.
Remarks
This method does not work if the Engine object is created using the OutprocLoader object.
