L_LTKRN_API L_INT L_PutPixelData(pBitmap, pData, nRow, nCol, uBytes)
Pointer to the bitmap handle referencing the bitmap.
Pointer to a buffer that contains the pixel data to set. This buffer should be able to store uBytes bytes.
The row number of the pixel. This is a zero-based value.
The column number of the pixel. This is a zero-based value.
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: (pBitmap->BitsPerPixel + 7) / 8.
| Value | Meaning |
|---|---|
| SUCCESS | The function was successful. |
| < 1 | An error occurred. Refer to Return Codes. |
The bitmap's memory must be locked when you use this function. Normally, call L_AccessBitmap to lock the memory before starting an operation that uses this function and then call L_ReleaseBitmap when the operation is finished.
This function should be called only for 8, 16, 24, 32, 48 and 64-bit bitmaps. For more information, refer to L_GetPixelData.
Win32, x64, Linux.
For an example, refer to L_GetPixelData.
