#include "ltwrappr.h"
virtual L_INT LBitmapBase::PutPixelData(pData, nRow, nCol, nBytes)
L_VOID * pData; |
/* pointer to a buffer */ |
L_INT nRow; |
/* row number of the pixel */ |
L_INT nCol; |
/* column number of the pixel */ |
L_INT nBytes; |
/* size of the buffer */ |
Changes the data of the specified pixel. No transformations are performed on the pixel data.
Parameter |
Description |
pData |
Pointer to a buffer that contains the pixel data to set. This buffer should be able to store nBytes bytes. |
nRow |
The row number of the pixel. |
nCol |
The column number of the pixel. |
nBytes |
Size of the buffer pointed to by pData. The size should be large enough to contain the data for the pixel. The minimum size can be calculated with the following formula: (LBitmapBase::GetBitsPerPixel + 7) / 8. |
Returns
SUCCESS |
The function was successful. |
< 1 |
An error occurred. Refer to Return Codes. |
