#include "ltwrappr.h"

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.

To update a status bar or detect a user interrupt during execution of this function, refer to LBase::EnableStatusCallback.

This function does not support 32-bit grayscale images. It returns the error code ERROR_GRAY32_UNSUPPORTED if a 32-bit grayscale image is passed to this function.
