virtual L_INT LBitmap::ApplyMathLogic(nFactor, uFlags)
L_INT nFactor; |
/*operation factor */ |
L_UINT uFlags; |
/* flag */ |
Performs specific mathematical or logical operations on the colors of a bitmap.
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. |
Comments
This function supports 12 and 16-bit grayscale and 48 and 64-bit color images. Support for 12 and 16-bit grayscale and 48 and 64-bit color images is available only in the Document/Medical toolkits.
