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. |
SUCCESS |
The function was successful. |
< 1 |
An error occurred. Refer to Return Codes. |
This function should be called only for 8, 16, 24, 32, 48 and 64-bit bitmaps. For more information, refer to LBitmapBase::GetPixelData.
