L_LTKRN_API L_INT L_PutPixelData(pBitmap, pData, nRow, nCol, uBytes)
Changes the data of the specified pixel. No transformations are performed on the pixel data.
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.

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.
Required DLLs and Libraries
