LBitmap::BumpMap

Summary

Adds a three-dimensional texture pattern created by applying the bump image to the destination image.

Syntax

#include "ltwrappr.h"

virtual L_INT LBitmap::BumpMap(pBumpBitmap, pBumpData, uFlags = 0)

virtual L_INT LBitmap::BumpMap(hBumpBitmap, pBumpData, uFlags = 0)

Parameters

pBITMAPHANDLE hBumpBitmap

Pointer to the bitmap handle referencing the Bump bitmap.

LBitmap * pBumpBitmap

Pointer to the bitmap object referencing the Bump bitmap.

pBUMPDATA pBumpData

Pointer to a BUMPDATA structure that contains information about the bump parameter.

L_UINT32 uFlags

Reserved for future use. Must be 0.

Returns

Value	Meaning
SUCCESS	The function was successful.
< 1	An error occurred. Refer to Return Codes.
