L_BumpMapBitmap

#include "l_bitmap.h"

L_LTIMGSFX_API L_INT L_BumpMapBitmap(pBitmapDst, pBumpBitmap, pBumpData, uFlags)

pBITMAPHANDLE pBitmapDst;	pointer to the bitmap handle
pBITMAPHANDLE pBumpBitmap;	pointer to the bitmap handle
pBUMPDATA pBumpData;	pointer to a structure
L_UINT32 uFlags;	flags

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

Parameter	Description
pBitmapDst	Pointer to the bitmap handle referencing the destination bitmap. This bitmap will be updated by the function.
pBumpBitmap	Pointer to the bitmap handle referencing the Bump bitmap.
pBumpData	Pointer to a BUMPDATA structure that contains information about the bump parameter.
uFlags	Reserved for future use. Must be 0.

Returns

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

Comments

This function does not support signed data images. It returns the error code ERROR_SIGNED_DATA_NOT_SUPPORTED if a signed data image is passed to this function.

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

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 in the Document and Medical Imaging toolkits.

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.
