Parameter |
Description |
|
nFactor |
Mathematical or logical operation factor. |
|
uFlags |
Flags that indicate the channel that will be used, the treatment of the input pixel values, the mathematical operation, and the treatment of the output pixel values. Use a bitwise OR ( | ) to specify one flag from each group. Refer to Flags for the LBitmap::ApplyMathLogic Function for the list of flags. |
Returns
|
SUCCESS |
The function was successful. |
|
< 1 |
An error occurred. Refer to Return Codes. |
